Setting Up Your Network Connection
This section allows you to refine your local network interface settings as well as your global settings that allow access to your workgroup and share folders.
Ethernet Interface Settings
Select Network > Interfaces, and then select the Ethernet tab. From this screen you can specify your network interface-specific settings. In the Standard Setting section, you can specify the IP address, network mask, speed/duplex mode, and MTU settings. In most networks where a DHCP server is enabled, you can simply specify the Use values from a DHCP server option to automatically set the IP address and network mask.

IP Assignment. Select either Use values from a DHCP server or Use values below. If you elect to assign the IP address using Use values from a DHCP server, NETGEAR advises that you set the lease time on the DHCP server/router to a value of at least a day. Otherwise, you might notice that the ReadyNAS Duo IP address changes even when ReadyNAS Duo has been powered down for only a few minutes. Most DHCP servers allow you to assign a static IP address for specified MAC addresses. If you have this option, this would be a good way to ensure your ReadyNAS Duo maintains the same IP address even in DHCP mode. If you assign a static IP address by selecting Use values below, be aware that the browser will lose connection to the ReadyNAS Duo device after the IP address has been changed. To reconnect after assigning a static IP address, open RAIDar and click Rescan to locate the device, and then reconnect.
Speed/Duplex Mode. If you have a managed switch that works best if the devices are forced to a particular speed or duplex mode, you can select the setting you want. NETGEAR advises that you keep the setting in an Auto-negotiation mode otherwise.

Figure 1-5

Configuring Your ReadyNAS Duo v1.1, April 2008
MTU. In some network environments, changing the default MTU value can fix throughput problems. NETGEAR advises that you leave the default setting otherwise.

Figure 1-6

In the Performance Setting area, the Enable jumbo frames option allows you to optimize the ReadyNAS Duo for large data transfers such as multiple streams of video playback. Select this option if your NIC and your gigabit switch support jumbo frames. Note: The ReadyNAS Duo supports a 7936 byte frame size, so for optimal performance, a switch capable of this frame size or larger should also be used.

Admin Password

The Admin Password tab allows you to change the administrator user password. The administrator user is the only user that can access FrontView, and this user has administrative privileges when accessing shares. Be sure to set a password different from the default password, and make sure that this password is kept in a safe place. Anyone who obtains this password can effectively change or erase the data on the ReadyNAS Duo.

Figure 1-8

As a safeguard, you are requested to enter a password recovery question, the expected answer, and an e-mail address. If, in the future, you forget the password, you can go to https://<ReadyNAS ip_address>/password_recovery. Successfully answering the questions there resets the Admin Password, and that new password is sent to the e-mail address you enter on this screen.

Setting Up User and Group Accounts
In the User & Group Accounts security mode, the Accounts tab screen allows you to manage user and group accounts on the ReadyNAS Duo. Managing Users To manage user accounts: 1. Select Manage Users from the drop-down menu. 2. Click the Add User tab to add a new user. You can add up to five users at a time. For each user, add the following information: User name, E-mail address User ID Select a group from the Group pull-down menu. Password Disk quota. 3. Click Apply to save your settings.
Figure 1-10 Configuring Your ReadyNAS Duo v1.1, April 2008 1-7
Only the user name field is required; however, you should specify a user e-mail address if you intend to set up disk quotas. Without an e-mail address, the user will not be warned when disk usage approaches the specified disk quota limit. If you do not wish to assign a disk quota, enter 0. If you wish to add a large number of users, select Import user list from the pull-down menu.

Figure 1-11

Here, you can upload a CSV (Comma Separated Value) formatted file containing the user account information. The format of the file is:
name1,password1,group1,email1,uid1,quota1 name2,password2,group2,email2,uid2,quota2 name3,password3,group3,email3,uid3,quota3 :

Please note the following: Spaces around commas are ignored. The name and password fields are required. If a listed group account does not exist, it is automatically created. Group and quota are set to the defaults if not specified. E-mail notification is not sent to the user if the field is omitted or left blank. UID is automatically generated if not specified. Empty fields are replaced with account defaults.
Examples of acceptable formats are as follows (note that you can omit follow-on commas and fields if you wish to accept the system defaults for those fields, or you can leave the fields empty):

fred,hello123

In this example, user fred has a password set to hello123, belongs to the default group, receives no e-mail notification, has a UID assigned automatically, and has a default quota.
barney,23stone,,barney@bedrock.com
In this example, user barney has a password set to 23stone, belongs to the default group, receives e-mail notification sent to barney@bedrock.com, has a UID assigned automatically, and has a default quota.
1-8 v1.1, April 2008 Configuring Your ReadyNAS Duo
NETGEAR ReadyNAS Duo User Guide wilma,imhiswif,ourgroup,wilma@bedrock.com,225,50
In this example, user wilma has a password imhiswif, belongs to the group ourgroup, receives email notification sent to wilma@bedrock.com, has a UID set to 225, and a quota set to 50 MB. Managing Groups To add a new group: 1. Select Manage Groups from the drop-down menu in the upper right corner. 2. Select the Add Group tab if it is not already selected. You can add up to five groups at a time. If you expect to have just one big set of users for one group, you can forego adding a new group and accept the default users group. 3. Click Apply to save your settings. If you want, a user can belong to multiple groups. Once you have created user accounts, you can specify secondary groups that the user can belong to. This allows for finer-grain settings for share access. For instance, you can have user Smithy in the General group also belong to the Finance group so Smithy can access shares restricted to only the Finance Group. When adding a new group, you can specify the amount of disk space you wish to allocate that group by setting a disk quota. A value of 0 denotes no limit. You can also set the Group ID, or GID, of the group that you are adding. You can leave this field blank and let the system automatically assign this value unless you wish to match your GID to your NFS clients.

1-14 v1.1, April 2008

Home Media Streaming Server provides streaming of videos, music, and pictures to popular networked DVD players. The streaming players often utilize the streaming client developed by Syabas. Similar to UPnP AV, this service is used to stream videos, music, and pictures from the reserved media share to these adapters. If you wish to change the location where the media files are stored, you can specify a different share and folder path. Note that this path is shared between the UPnP AV and this service.

Discovery Services

Bonjour service provides a simple way of discovering various services on the ReadyNAS Duo. Bonjour currently provides an easy way to connect to FrontView, IPP printing, and AFP services. OS X has built-in Bonjour support, and you can download Bonjour for Windows from Apples website. UPnP provides a means for UPnP-enabled clients to discover the ReadyNAS Duo on your LAN.

Figure 1-17

Installed AddOns
Two add-ons allow you to download files unattended using the Bit Torrent technology and share your photos on the ReadyNAS photo-share site. Bit Torrent. The ReadyNAS Duo enables peer-to-peer file sharing and allows the ReadyNAS Duo to queue and index torrent download files. ReadyNAS Photos. The ReadyNAS Duo allows you to share photos with select users on the Internet. You must install ReadyNAS Photos software which is available on the ReadyNAS site. Simply click Install ReadyNAS Photos and follow the on-screen prompts. Once you have
enabled this feature and downloaded the software, you will be able to share photos located in your Pictures folder. To download ReadyNAS Photos software: 1. Click Install ReadyNAS Photos. The ReadyNAS Photos Installers screen displays.

Figure 1-18

2. Select the install version that is appropriate for your operating system. When the installation has completed, the ReadyNAS Photos icon will be installed on your desktop. 3. Create a ReadyNAS Photos profile. You will need the User ID and Password that you selected to log in to ReadyNAS Photos.

Figure 1-19

1-16 v1.1, April 2008
4. When the ReadyNAS Photos login screen displays, enter your User ID and Password and click the arrow.

5. A screen similar to the one below will display. Connect ReadyNAS Photos to your ReadyNAS Duo by clicking Connect.

Figure 1-27

Partitions on the storage devices must be one of the following file system formats: FAT32 NTFS Ext2 Ext3

1-22 v1.1, April 2008

To the right of the access icons are command options for the device. The following commands are available:
Disconnect This option prepares the USB partition for disconnection by correctly unmounting the file system. In most cases, you can safely disconnect the device without first unmounting; however, the Disconnect command ensures that any data still in the write cache is written out to the disks and that the file system is properly closed. The Disconnect option unmounts all partitions on the device. Once disconnected, physically remove and reconnect to the ReadyNAS Duo to regain access the USB device,. In cases where you attach multiple storage devices and wish to determine which device corresponds to the device listing, the Locate command causes the device LED to blink, if present. This option formats the device as a FAT32 file system. FAT32 format is easily recognizable by most newer Windows, Linux, and Unix operating systems. This option formats the device as an EXT3 file system. Select this option if you will be accessing the USB device mainly from Linux systems or ReadyNAS Duo devices. The advantage of EXT3 over FAT32 is that file ownership and mode information can be retained using this format, whereas this capability is not there with FAT32. Although not natively present in the base operating system, Ext3 support for Windows and OS X can be added. The installation images can be downloaded from the Web.

Locate

Format FAT32 Format EXT3
When the USB device is unmounted, you have the option of renaming it. The next time the same device is connected, it will use the new name rather than the default USB_FLASH_n or USB_HDD_n naming scheme. The USB storage shares are listed in the Share screen, and access restrictions can be specified there. The share names reflect the USB device names. USB Flash Device Option Toward the lower portion of the USB Storage screen is the USB Flash Device Option section (see Figure 1-27 on page 1-22). There, you can elect to copy the content of a USB flash device automatically on connection to a specified share. Files are copied into a unique timestamp folder to prevent overwriting previous contents. This is useful for uploading pictures from digital cameras and music from MP3 players without needing to power on a PC. In User security mode, an additional option to set the ownership of the copied files is available.

Managing Your Shares

The Shares menu provides all the options pertaining to share services for the ReadyNAS Duo device. This entails share management (including data and print shares), volume management, and share service management.

1-28 v1.1, April 2008

Figure 1-33
Recycle Bin. The ReadyNAS Duo can have a Recycle Bin for each share for Windows users. The Enable Recycle Bin option is shown at the bottom of the CIFS screen. When this check box is selected, whenever you delete a file, the file gets inserted into the Recycle Bin folder in the share rather than being permanently deleted. This allows for a grace period during which users can restore deleted files.

Figure 1-34

You can specify how long to keep the files in the Recycle Bin and how large the Recycle Bin can get before files get permanently erased. Advanced CIFS Permission. The Advanced CIFS Permission section offers options for setting the default permission of new files and folders created through CIFS. The default permission of newly created files is read/write for the owner and owners group and read-only for
others (that is, everyone). Permission for newly created folders is read/write for everyone. If the default does not satisfy your security requirement, you can change it here. Opportunistic locking (often referred to as oplocks) enhances CIFS performance by allowing files residing on the NAS to be cached locally on the Windows client, thus eliminating network latency when the files are constantly accessed.

Figure 1-35

Advanced Options The Advanced Options tab offers advanced low-level file manipulation options that can affect remote file access through all file protocol interfaces. Care should be taken before you use these options as anything that changes ownership and permissions might not be easily reversible.

1-30 v1.1, April 2008

Figure 1-36
Advanced Share Permission. The Advanced Share Permission section offers the options to override the default ownership and permission of the share folder on the embedded file system and to permeate these settings to all files and folders residing on the selected share. The Set ownership and permission for existing files and folders option performs a one-time change. Depending on the size of the share, this can take a while to finish. You can also grant rename and delete privilege to non-owners of the files option. In a collaborative environment, you might want to enable this option. In a more security-conscious environment, you might want to disable this option.

USB Shares

USB storage devices are shared using the name of the device appended with the partition number. You can change the base device name in Volumes > USB Storage, if you want. The ReadyNAS Duo attempts to remember the name as long as there is a unique ID associated with the USB device so that the next time the device is connected, the same share name(s) will be available. Share access restrictions are not saved across disconnects, however.

Figure 1-46

Select the radio button next to the print job and click Delete Print Job to remove a job (or all jobs) from the print queue.
Managing Your ReadyNAS Duo System
To set up and manage your ReadyNAS Duo effectively, make sure that you review the settings in the following sections, and implement any necessary modifications or updates.
An accurate time setting on the Clock screen is required to ensure proper file timestamps. You can access the Clock screen by selecting System > Clock from the main menu. System Time The Select Timezone section and the Select Current Time section of the Clock screen allow you to set the Timezone, and the Date and Time.

Figure 1-47

1-42 v1.1, April 2008
NTP Option You can elect to synchronize the system time on the device with a remote NTP (Network Time Protocol) server. You can elect to keep the default servers or enter up to two NTP servers closer to your locale. You can find an available public NTP servers by searching the Web.

Alerts

In the event of a device or an enclosure failure, a quota violation, low-disk space warning, and other system events requiring your attention, e-mail alerts are sent. The Alerts screen is accessed by selecting System > Alerts from the main menu. Alerts Contacts The Contacts tab allows you to specify up to three e-mail addresses where system alerts will be sent. The ReadyNAS Duo device has a robust system monitoring feature and sends e-mail alerts if something appears to be wrong or when a device has failed. Make sure to enter a primary e-mail address and a backup one if possible.

Figure 1-48

Some e-mail addresses can be tied to a mobile phone. This is a great way to monitor the device when you are away from your desk.
Alerts Settings This ReadyNAS Duo device has been preconfigured with mandatory and optional alerts for various system device warnings and failures. The Settings tab allows you to control the settings for the optional alerts.

Figure 1-49

NETGEAR strongly recommends that you keep all alerts enabled; however, you might choose to disable an alert if you are aware of a problem and wish to temporarily disable it. At the bottom of the screen in the Other Alert Settings section, there are a couple of additional options of note. Selecting the Power-off NAS when a disk fails or no longer responds option gracefully powers off the ReadyNAS Duo if a disk failure or a disk remove event is detected. Selecting the Power-off NAS when disk temperature exceeds safe level gracefully powers off the ReadyNAS Duo when the disk temperature exceeds the nominal range. SMTP The ReadyNAS Duo device has a built-in e-mail message transfer agent (MTA) that is set up to send alert e-mail messages from the device. Some corporate environments, however, might have a firewall that blocks untrusted MTAs from sending out messages.

Since Windows runs in case-insensitive mode, one side-effect of enabling this option is that two file names with different cases (for example, ABC and abc) appear as two files but, when you open one file, the other file might actually open. Another effect of this option is that, in Explorer, you now need to enter the exact case for search strings for the Find option (that is, searching for abc no longer returns file ABC). Some Windows applications that assume case-insensitive operations (for example, BackupExec) may have problems. Do not enable this option if you have clients accessing the NAS running Windows NT/95 or earlier.
The Enable fast USB disk writes option speeds up USB write access by allowing access to the USB device in asynchronous mode. If you enable this option, do not remove the USB device without properly unmounting it. Failure to do so can compromise data integrity on the device.
Adding a UPS for Performance Adding a UPS to the NAS is an easy way to protect against power failures, but as mentioned in Performance on page 1-45, a UPS can also safely allow for a more aggressive performance setting. Simply connect the NAS power cable to the UPS, and connect the UPS USB monitoring cable between the UPS and the NAS. The UPS is detected automatically and shows up in the Status bar. You can move the mouse pointer over the UPS LED icon to display the current UPS information and battery life. Note: Note that alert notification and automatic system optimization is available only with UPS that utilizes a USB monitoring interface. You are notified by e-mail whenever the status of the UPS changes; for example, when a power failure forces the UPS to be in battery mode or when the battery is low. When the battery is low, the NAS device automatically shuts down safely. Make sure to adjust the optimization settings in the Performance screen if you wish to take advantage of the available options.

Language

The Language Setting screen offers the option of setting the ReadyNAS Duo device to the appropriate character set for file names.

Figure 1-52

For example, selecting Japanese allows you to share files with Japanese names in Windows Explorer.

Figure 1-53

It is best to select the appropriate language based on the region where the device will be operated.

1-48 v1.1, April 2008

Note: This option does not set the web browser language displaybrowser settings must be done using the browser language option. If you wish, you can select the Allow Unicode for user, group and share names check box to allow for greater flexibility in non-English speaking regions. This option, once selected, cannot be reversed. Note: HTTP and WebDAV access do not work with Unicode user names. Other restrictions might exist. If your FTP client uses different character encoding from the NAS character encoding specified in Unicode, the NAS FTP server will convert it if you select the Enable character encoding conversion for FTP clients check box.

Figure 3-4

On the front of the ReadyNAS Duo device, a failed disk is identified by an amber LED. The left most LED is disk channel 1; the next one is disk channel 2. Take note of the failed channel.
Ordering a Replacement Disk
On the main menu, select Status > Health. Take note of the disk vendor and model utilized on your ReadyNAS Duo system. It is best to replace a failed disk with the same disk model. Contact the disk vendor, and arrange to have the disk replaced if the disk is still under warranty. A disk RMA from the vendor requires that you provide the serial number of the disk. To locate the serial number, open the case and take out the failed disk (see the following sections for replacement instructions for your disk model). If the disk is no longer under warranty, you can obtain a disk of the same capacity or larger from your ReadyNAS Duo retailer.
Replacing a Failed Disk on the ReadyNAS Duo
When a Disk Status LED blinks slowly, it is an indication of a failed disk. The ReadyNAS Duo supports hotswap bays, so there is no need to power down the device.
Maintenance and Administration v1.1, April 2008
To replace the disk: 1. Open the disk tray door. 2. Press the button under the failed disk. The latch pops out.

Figure 3-5

3. Pull out the disk tray and remove the screws. 4. Replace the failed disk, reassemble, and slide the disk tray back in. Make sure that the hard disk connectors are facing away from you when you reassemble the disk.

Maintenance and Administration

Figure 3-6

The ReadyNAS Duo system performs RAID synchronization in the background, and notifies you by e-mail when synchronization is complete.
Resynchronizing the Volume
If you had to power off to replace the failed disk, turn on the power on the ReadyNAS Duo. The RAID volume automatically resynchronizes with the new disk in the background. The process takes several hours depending on disk size. During the resync process, the ReadyNAS Duo can be used as normal, although access will be slower until the volume is finished resynchronizing. You will be notified by e-mail when the resync process is complete.
Resetting Your System (System Switch)
Refer to the Installation Guide included in the shipping box (a PDF of the Installation Guide is also on your Installation CD) for the location of the System Reset switch on the back of the ReadyNAS Duo. The System Reset switch allows you to perform two functions:
Maintenance and Administration v1.1, April 2008 3-5
1. Reinstall the ReadyNAS Duo firmware. 2. Reset the ReadyNAS Duo back to the factory default settings. Typically, you should not need to resort to options (1) and (2) unless you exhausted all other means of recovering your system. You might want to reinstall the ReadyNAS Duo firmware as a first step, if the ReadyNAS Duo had been working normally but a configuration change makes it inaccessible. If this does not work or you wish to set the ReadyNAS Duo back to a factory default state, you can do so following these instructions below: To re-install the ReadyNAS Duo firmware: Use a paper clip to depress the switch while the system is off. Continue to depress the reset switch while powering on the system for approximately 5 seconds until the disk LEDs flash once to signify that the command has been accepted. The firmware installation takes several minutes to complete. The Status LED in the front will be solid green when the process is complete. The installation does not affect the data on the ReadyNAS Duo. Warning: Make sure that you do not continue to press the reset switch after the LEDS flash once, otherwise a Factory Default will occur that erases your data. (see below) To set the ReadyNAS Duo device to Factory Default: Use the same process, except you must hold the System Reset switch for 30 seconds after powering on the system. You will see the disk LEDs flash for a second time to signify that the command has been accepted. Warning: This process reinstalls the firmware and resets all disk configurations, wiping out any data you might have on the NAS.

Configuring Your ReadyNAS

Global Network Settings

Figure 1-9
Hostname The Hostname you specify is used to advertise the ReadyNAS on your network. You can use the hostname to address the ReadyNAS in place of the IP address when accessing the ReadyNAS from Windows, or over OS X using SMB. This is also the name that appears in the RAIDar scan list. The default hostname is nas- followed by the last three bytes of your primary MAC address. Default Gateway The Default Gateway specifies the IP address of the system where your network traffic is routed if the destination is outside your subnet. In most homes and smaller offices, this is the IP address of the router connected to the cable modem or your DSL service. If you selected the DHCP option in the Ethernet or Wireless tab, the Default Gateway field is automatically populated with the setting from your DHCP server. If you selected the Static option, you can manually specify the IP addresses of the default gateway server here.
DNS Settings The DNS area allows you to specify up to three Domain Name Service servers for hostname resolution. The DNS service translates host names into IP addresses. If you selected the DHCP option in the Ethernet or Wireless tab, the Domain Name Server fields are automatically populated with the DNS settings from your DHCP server. If you selected the Static option, you can manually specify the IP addresses of the DNS servers and the domain name here.
The WINS option allows you to specify the IP address of the WINS (Windows Internet Naming Service) server. A WINS server is typically a Windows server on the network that allows the ReadyNAS or other devices on the network to be browsed from other subnets.

Figure 1-10

If you do not have an existing WINS server, you can designate the ReadyNAS to be one. Simply select the Become a WINS server check box, and configure your Windows PC to specify the ReadyNAS IP address as the WINS server. This can be useful if you wish to browse by hostname across multiple subnets (for example, over VPN).

Mac. Enabling rsync service on the ReadyNAS allows clients to use rsync to initiate backups to and from the ReadyNAS.

Figure 1-22

Streaming Services
The built-in streaming services on the ReadyNAS allow you to stream multi-media content directly from the ReadyNAS, without the need to have your PC or Mac powered on.

Figure 1-23

SlimServer provides music streaming to the popular Squeezebox music players from Slim Devices. You can click the http setup link for more detailed configuration options. iTunes Streaming Server enables iTunes clients to stream media files straight from the ReadyNAS. You can click the http setup link for more detailed configuration options. UPnP AV provides media streaming service to stand-alone networked home media adapters and networked DVD players that support the UPnP AV protocol or are Digital Living Network Alliance (DLNA) standard compliant. The ReadyNAS comes with a reserved media share that is advertised and recognized by the players. Simply copy your media files to the Videos, Music, and Pictures folders in that share to display them on your player. If you wish, you can specify a different media path where your files reside.

1-20 v1.0, October 2007

Home Media Streaming Server provides streaming of videos, music, and pictures to popular networked DVD players. The streaming players often utilize the streaming client developed by Syabas. Similar to UPnP AV, this service is used to stream videos, music, and pictures from the reserved media share to these adapters. If you wish to change the location where the media files are stored, you can specify a different share and folder path. Note that this path is shared between the UPnP AV and this service.

Discovery Services

Bonjour service provides a simple way of discovering various services on the ReadyNAS. Bonjour currently provides an easy way to connect to FrontView, IPP printing, and AFP services. OS X has built-in Bonjour support, and you can download Bonjour for Windows from Apples website. UPnP provides a means for UPnP-enabled clients to discover the ReadyNAS on your LAN.

Figure 1-24

Understanding Volume Management

The ReadyNAS family consists of two RAID volume technologies: Flex-RAID, utilizing the industry-standard RAID levels 0, 1, and 5; and X-RAID, NETGEAR-patented expandable RAID technology. Your system defaults to one or the other; however, you can switch between the two modes through a factory default reset process described in Resetting Your System (System Switch) on page 3-6.
There are advantages to both technologies. Flex-RAID: The default volume can be deleted and re-created, with or without the snapshot reserved space. Hot spare disk is supported. Full volume management is availableyou can create a volume utilizing RAID level 0, 1, or 5, specify the size of the volume, delete a disk from a volume, assign a hot spare, and so on. Multiple volumes are supported, each with a different RAID level, snapshot schedule and disk quota definition. Each disk can be replaced, one by one, then rebuilt; after the last disk is replaced, another data volume utilizing the newly added capacity can be configured.
X-RAID: One-volume technology, but supports volume expansion, either by with the addition of more disks or the replacement of an existing disk with larger capacity disks. You can start out with one disk, and add up to three more disks when you need them or can afford them. Volume management is automatic. Add a second disk, and it becomes a mirror to the first. Add a third disk and your capacity doubles; add a fourth, and your capacity triplesthe expansion occurring while redundancy is maintained. In the future, you will be able to replace disks, one at a time, have each one finish rebuilding and, after the last disk is replaced, your volume will automatically expand to utilize the new capacity.
Volume Management for Flex-RAID
If you want to reconfigure the default volume C, split it into multiple volumes, specify a different RAID level, or specify a larger reserved space for snapshots, you need to reconfigure your volume. The first step is to delete the existing volume you want to replace.

1-22 v1.0, October 2007

Deleting a Volume To delete a volume, select the Volume tab of the volume you wish to delete (if there are multiple volumes) and click Delete Volume (in this case only Volume C is configured). Warning: Make sure that you back up the files you wish to keep before deleting a volume. All shares, files, and snapshots residing on that volume will be deleted are non-recoverable!

Figure 1-25

You are asked to confirm your intention by typing DELETE VOLUME.

Figure 1-26

Adding a Volume After deleting the volume, Add Volume tab displays listing the available configurable space on the hard disks. All the disks are selected by default. You can elect to specify a hot spare disk if you wish. A hot spare remains in standby mode and automatically regenerates the data from a failed disk from the volume. A hot spare disk is available for RAID level 1 and RAID level 5 only if there are enough disks to fulfill the required minimum plus one.

Figure 1-27

To add a volume: 1. Select the hard disks. In this example, we select the first three disks and elect not to specify any of them as a hot spare. 2. Select the RAID level. RAID level determines how the redundancy, capacity utilization, and performance are implemented for the volume. See Appendix A, RAID Levels Simplified, for more information. Typically in a configuration of three or more disks, RAID level 5 is recommended. In our example, we selected RAID level 5 for the three selected disks. 3. Specify the reserve space for a snapshot. Next, select the percentage of the volume you wish to allocate for snapshots. You can specify 0 if you wish to disable snapshot capability, or you can specify a percentage in 5 percent increments from 5 to 50 percent. The percentage represents the amount of data you think changes while the snapshot is active. This typically depends on how often you schedule your snapshot to occur (see Taking and Scheduling Snapshots on page 1-28), and the maximum amount of data (plus padding) you think changes during that time. Make sure to allocate enough space for a worst case as the snapshot becomes unusable when its reserved space runs out. In our example, we selected 10 percent of the volume to be reserved for snapshots. Note: If you do not reserve any space for snapshots, the snapshot tab is not displayed in the Volume tab. 4. Specify the desired volume size. After you specify the volume parameters, enter the appropriate volume sizeif you wish to configure a smaller volume size than the maximum displayed. The resulting volume will be approximately the size that is specified.
1-24 v1.0, October 2007 Configuring Your ReadyNAS
In our example, we kept the maximum size that was calculated. 5. Click Apply, and wait for the instruction to reboot the system. It typically takes about 1 minute before you are notified to reboot. After rebooting, you are notified by e-mail when the volume has been added. Use RAIDar to reconnect to the NAS device. RAID Settings After you have added a volume, you can return to the Volume tab and click the RAID Settings tab to display the current RAID information and configuration options for the volume. Notice that the disk on Channel 4 that we did not configure is listed in the Available Disks section. We can add this disk as a hot spare by clicking Make hot spare.

Figure 1-28

We can also remove a disk from the volume by clicking Remove. The volume will still be available but in a non-redundant state. An additional disk failure would render this volume unusable. Note: The Remove operation is a maintenance feature. NETGEAR recommends that you do not use it in a live environment. Its function is equivalent to hot-removing the disk or simulating a disk failure. The Locate option is a way to verify that a disk is correctly situated in the expected disk slot. Clicking Locate causes disk LED to blink for 15 seconds.

Volume Management for X-RAID
The X-RAID technology offers a simplified approach to volume management. X-RAID works on the premise that what most people want to do with their data volume over time is either adding redundancy or expanding it without the headaches usually associated with doing that. By using simple rules, X-RAID is able to hide all the complexities yet provide volume management features previously available only in enterprise-level storage solutions. X-RAID Redundancy Overhead. To maintain redundancy from disk failure, X-RAID requires a one-disk overhead. In a two-disk X-RAID volume, the usable capacity is one disk. In a three-disk X-RAID volume, the usable capacity is two disks. In a four-disk X-RAID volume, the usable capacity is three disks. X-RAID has One Data Volume. X-RAID devices have only one data volume. This volume encompasses one to four disks, utilizing the capacity of the smallest disk from each disk. For instance, if you had one 80 GB disk and two 250 GB disks, only 80 GB from each disk is used in the volume. (The leftover space on the 250 GB disks is reclaimed only when the 80 GB disk is replaced with a 250 GB or greater capacity disk. See Replacing All Your Disks for More Capacity on page 1-27.)

Figure 1-29

Adding a Second Disk for Redundancy A one-disk X-RAID device has no redundancy and provides no protection from a disk failure. However, if and when you feel the need for redundancy, simply power down the device, add a new disk with at least the capacity of the first disk, and power on. Depending on the size of the disk,
1-26 v1.0, October 2007 Configuring Your ReadyNAS
within a few hours, your data volume will be fully redundant. The process occurs in the background, so access to the ReadyNAS is not interrupted. Adding a Third and Fourth Disk for More Capacity At a certain point, you will want more capacity. With typical RAID volumes, you have to back up your data to another system (with enough space), add a new disk, reformat your RAID volume, and restore your data back to the new RAID volume. Not so with X-RAID. Simply add the third disk using the ReadyNAS hot-swap trays. If you are adding multiple disks at the same time, or if your ReadyNAS is not hot-swap capable, power down the ReadyNAS, add the disk(s), and power back on. The X-RAID device initializes and scans the newly added disk(s) for bad sectors in the background. You can continue working normally without any lag in performance. When the process finishes, you will be alerted by e-mail to reboot the device. During the boot process, your data volume will be expanded. This process typically takes about 15 to 30 minutes per disk to several hours or longer, depending on the size of your disks, or the quantity of data on your volume. A 250 GB disk takes approximately 30 minutes. Access to the ReadyNAS is not permitted during this time. You will be notified by e-mail when the process is complete. After you receive your e-mail, the ReadyNAS will have been expanded with the capacity from your new disk(s). Replacing All Your Disks for More Capacity A year or so down the line when you find the need more disk space, and 600 GB disks are available at an attractive price, you can expand your volume capacity by replacing the existing disks. Keep in mind that you must power down several times to replace out your old disks. First, power down the ReadyNAS, replace the first disk with the large-capacity disk, and then reboot. If your ReadyNAS supports hot-swapping, you can hot-swap the disk without powering down. The ReadyNAS will detect that a new disk was put in place and resynchronizes the disk with data from the removed disk. This process takes several hours, depending on disk capacity. The disk is initialized and scanned for bad sectors first before the rsync process is started. The total time from the start of initialization to the end of resynchronization can be around 5 hours or more, depending on disk capacity. You will be notified by e-mail upon completion. Upon completion, power down, replace the second disk with another large-capacity disk, and reboot. This process is the same as for the first disk; repeat this process for the third and fourth disks, as well.

USB Storage

The USB tab displays the USB disk and flash devices connected to the ReadyNAS, and offers various options for these devices. A flash device appears as USB_FLASH_1 and a disk device appears as USB_HDD_1. If you have multiple devices, they appear appended by an increasing
Configuring Your ReadyNAS v1.0, October 2007 1-31
device number; for example, USB_HDD_2. If the device contains multiple partitions, the partitions are listed beneath the main device entry.

Figure 1-35

Partitions on the storage devices must be one of the following file system formats: FAT32 NTFS Ext2 Ext3
To the right of the access icons are command options for the device. The following commands are available:
Disconnect This option prepares the USB partition for disconnection by correctly unmounting the file system. In most cases, you can safely disconnect the device without first unmounting; however, the Disconnect command ensures that any data still in the write cache is written out to the disks and that the file system is properly closed. The Disconnect option unmounts all partitions on the device. Once disconnected, physically remove and reconnect to the ReadyNAS to regain access the USB device,. In cases where you attach multiple storage devices and wish to determine which device corresponds to the device listing, the Locate command causes the device LED to blink, if present.

Locate

1-32 v1.0, October 2007

Format FAT32 Format EXT3

This option formats the device as a FAT32 file system. FAT32 format is easily recognizable by most newer Windows, Linux, and Unix operating systems. This option formats the device as an EXT3 file system. Select this option if you will be accessing the USB device mainly from Linux systems or ReadyNAS devices. The advantage of EXT3 over FAT32 is that file ownership and mode information can be retained using this format, whereas this capability is not there with FAT32. Although not natively present in the base operating system, Ext3 support for Windows and OS X can be added. The installation images can be downloaded from the Web.
When the USB device is unmounted, you have the option of renaming it. The next time the same device is connected, it will use the new name rather than the default USB_FLASH_n or USB_HDD_n naming scheme. The USB storage shares are listed in the Share screen, and access restrictions can be specified there. The share names reflect the USB device names. USB Flash Device Option Toward the lower portion of the USB Storage screen is the USB Flash Device Option section (see Figure 1-35 on page 1-32). There, you can elect to copy the content of a USB flash device automatically on connection to a specified share. Files are copied into a unique timestamp folder to prevent overwriting previous contents. This is useful for uploading pictures from digital cameras and music from MP3 players without needing to power on a PC. In User security mode, an additional option to set the ownership of the copied files is available.

Managing Your Shares

The Shares menu provides all the options pertaining to share services for the ReadyNAS device. This entails share management (including data and print shares), volume management, and share service management.

Figure 1-36

Adding Shares
To add a share: 1. From the main menu, select Volumes > Volume Settings. If more than one volume is configured, click on the volume you wish to add the share. 2. Select Add Shares. Add Shares has two views, depending on the security mode. In the Add Shares screen, enter the share name, description and, optionally, the password and disk quota. (The share password and share disk quota are available only in the security mode).

Figure 1-37

1-34 v1.0, October 2007
In the User or Domain security modes, the Add Share tab consists only of fields for the share name and description. Password and disk quotas are account-specific. In either case, you can add up to five shares at a time. Once you finish adding the shares, refer to Chapter 2, Accessing Shares from Your Operating System for instructions on how to access them from different client interfaces.

Managing Shares

Once you have added shares, you can manually fine-tune share access by selecting Share List. This screen has two views, one for Share Security mode and one for User and Domain mode. They are similar except for the password and disk quota prompts which appear only in Share mode.

Figure 1-38

If you want to delete a share, select the check box on the far right of the share listing and click Delete. The columns to the left of the Delete check box represent the services that are currently available. The access icons in those columns summarize the status of the service and the access rights to the share for each of the services. Move the mouse pointer over the access icons to view the access settings.
Figure 1-39 Configuring Your ReadyNAS v1.0, October 2007 1-35
The settings are as follows: Disabled. Access to this share is disabled. Read-only Access. Access to this share is read-only. Read/Write Access. Access to this share is read/write. Read Access with exceptions. Either (1) access to this share is read-only and allowed only for specified hosts, (2) access is read-only except for one or more users or groups that are granted read/write permission, or (3) access is disabled except for one or more users or groups that are granted read-only privilege. Write Access with exceptions Either (1) access to this share is read/write and allowed only for specified hosts, (2) access is read/write except for one or more users or groups that are restricted to read-only access, or (3) access is disabled except for one or more users or groups that are granted read/write privilege.

USB Shares

USB storage devices are shared using the name of the device appended with the partition number. You can change the base device name in Volumes > USB Storage, if you want. The ReadyNAS attempts to remember the name as long as there is a unique ID associated with the USB device so that the next time the device is connected, the same share name(s) will be available. Share access restrictions are not saved across disconnects, however.

Figure 1-46

Note: Although access authorization is based on user login in non-Share mode, files saved on the USB device, regardless of the user account, are with UID 0. This is to allow easy sharing of the USB device with other ReadyNAS and PC systems.

Configuring Backup Jobs

The Backup Manager integrated with the ReadyNAS allows the ReadyNAS to act as a powerful backup appliance. Backup tasks can be controlled directly from the ReadyNAS without the need for a client-based backup application. With the flexibility to support incremental backups over CIFS/SMB, NFS, and rsync protocols, and full backups over FTP and HTTP protocols, the ReadyNAS can act as a simple central repository for both home and office environments. And with multiple ReadyNAS systems, you can set up one ReadyNAS to back up another directly.

1-42 v1.0, October 2007

Adding a New Backup Job
To create a new backup job, select Add a New Backup Job. A 4-step procedure screen for creating a job displays.

Figure 1-47

Step 1 Select Backup Source The backup source can be located remotely, or it can be a public or a private home share, or all home shares on the ReadyNAS. A USB device appears as a share, so if you want to back up a USB device, select a share name. If you want to back up data from a remote source, select from one of the following: Windows/NAS (Timestamp). Select this if you wish to back up a share from a Windows PC. Incremental backups use timestamps to determine whether files should be backed up. Windows/NAS (Archive Bit). Select this if you wish to back up a share from a Windows PC. Incremental backups use the archive bit of files, similar to Windows, to determine whether they should be backed up. Website. Select this if you wish to back up a website or a website directory. The backed up files include files in the default index file and all associated files, as well as all index file links to web page image files. FTP site. Select this if you wish to back up an FTP site or a path from that site. NFS server. Select this option if you wish to back up from a Linux or UNIX server across NFS. Mac OS X users can also use this option by setting up a NFS share from the console terminal.

1-43 v1.0, October 2007

Rsync server. Select this if you wish to perform backups from a rsync server. Rsync was originally available for Linux and other flavors of UNIX, but has lately become popular under Windows and Mac for its efficient use of incremental file transfers. This is the preferred backup method between two ReadyNAS devices.
Once you have selected a backup source, you can enter the path from that source. If you selected a ReadyNAS share, you can either leave the path blank to backup the entire share, or enter a folder path. Note that you should use forward slashes (/), in place of backslashes (\). If you selected a remote source, each remote protocol uses a slightly different notation for the path. If the path field is empty, selecting the remote source in the pull-down menu shows an example format of the path. Following are some examples: Examples of an FTP path: ftp://myserver/mypath/mydir ftp://myserver/mypath/mydir/myfile Examples of a website path: http://www.mywebsite.com http://192.168.0.101/mypath/mydir Examples of a Windows or remote NAS path: //myserver/myshare //myserver/myshare/myfolder //192.168.0.101/myshare/myfolder Examples of an NFS path: myserver:/mypath 192.168.0.101:/mypath/myfolder Examples of a Rsync path: myserver::mymodule/mypath 192.168.0.101::mymodule/mypath Examples of a local path: myfolder media/Videos My Folder
1-44 v1.0, October 2007 Configuring Your ReadyNAS
My Documents/My Pictures With a remote source, you might need to enter a login and password to access the share. If you are accessing a password-protected share on a remote ReadyNAS server configured for Share security mode, enter the name of the share name for login. To make sure that you have proper access to the backup source, click Test Connection before continuing. Step 2 Select Backup Destination The Step 2 process is almost identical to Step 1 except that you are now specifying the backup destination. If you selected a remote backup source, you need to select a public or a private home share on the ReadyNAS (either the source or destination must be local to the ReadyNAS). If you selected a ReadyNAS share for the source, you can either enter another local ReadyNAS share for the destination, or you can specify a remote backup destination.

Figure 1-57

Some e-mail addresses can be tied to a mobile phone. This is a great way to monitor the device when you are away from your desk.
Alerts Settings This ReadyNAS device has been preconfigured with mandatory and optional alerts for various system device warnings and failures. The Settings tab allows you to control the settings for the optional alerts.

Figure 1-58

NETGEAR strongly recommends that you keep all alerts enabled; however, you might choose to disable an alert if you are aware of a problem and wish to temporarily disable it. At the bottom of the screen in the Other Alert Settings section, there are a couple of additional options of note. Selecting the Power-off NAS when a disk fails or no longer responds option gracefully powers off the ReadyNAS if a disk failure or a disk remove event is detected. Selecting the Power-off NAS when disk temperature exceeds safe level gracefully powers off the ReadyNAS when the disk temperature exceeds the nominal range. SNMP If you utilize an SNMP management system such as HP OpenView or CA UniCenter to monitor devices on your network, you can set up the ReadyNAS device to work within this infrastructure.

1-54 v1.0, October 2007

Figure 1-59
To set up SNMP service: 1. Select the SNMP tab to display the SNMP settings. 2. Select the Enable SNMP service check box. You can leave the Community field set to public, or specify a private name if you have opted for a more segregated monitoring scheme. 3. Enter a host name or an IP address in the Trap destination field. This is where all trap messages will be sent. The following system events generate a trap: Abnormal power voltage Abnormal board enclosure temperature Fan failure UPS connected UPS detected power failure RAID disk sync started and finished RAID disk added, removed, and failure Snapshot invalidated 4. If you wish to limit SNMP access to only a secure list of hosts, specify the hosts in the Hosts allowed access field. 5. Click Apply to save your settings. When you have saved the SNMP settings on the ReadyNAS, you can import the NETGEAR SNMP MIB to your SNMP client application. The NETGEAR MIB can be obtained from the included Installation CD or downloaded from the NETGEAR Support site at http://www.netgear.com/support.
SMTP The ReadyNAS device has a built-in e-mail message transfer agent (MTA) that is set up to send alert e-mail messages from the device. Some corporate environments, however, might have a firewall that blocks untrusted MTAs from sending out messages. If you were unable to receive the test message from the Alerts Settings tab, it might have been blocked by the firewall. In that case, specify an appropriate SMTP server in this tab.

Figure 1-60

Internet Service Providers (ISPs) for home might also block untrusted MTAs. Furthermore, they might allow you to specify their SMTP server but requires that you enter a user login and password to send out e-mailthis is common with most DSL services. If this is the case, simply enter the user name and password in the fields provided.

Performance

If you wish to tweak the system performance, select Performance from the main menu. Note that some of the settings suggest that you utilize an Uninterruptible Power Supply (UPS) before enabling that option: NETGEAR recommends that you select the Disable full data journaling only if the NAS has UPS protection. Without battery backup, there is a small chance that parity written to a disk in a RAID set might become out of sync with the data disks if a power failure suddenly occurs, possibly causing incorrect data to be recovered if one disk fails. Without full data journaling, disk write performance increases substantially.

1-56 v1.0, October 2007

Figure 1-61
Select Disable journaling if you understand the consequences of this action, and you do not mind a long file system check (only after unexpected power failures). File system journaling allows disk checks of only a few seconds verses possibly an hour or longer without journaling. Disabling journaling improves disk write performance slightly. Note: You can buy a UPS with USB monitoring at a very reasonable cost. By safely allowing the performance options to be checked, you can effectively double your write performance and provide uninterrupted service of your ReadyNAS for a very low price.
The Optimize for OS X option provides the best performance in Mac OS X environments when connected to the ReadyNAS through the SMB/CIFS protocol. This option, however, introduces compatibility issues with Windows NT 4.0; do not enable this option if this device will be accessed by Windows NT 4.0 clients. The Enable fast CIFS writes option allows for fast write performance by enabling aggressive write-back caching over CIFS. Do not enable this option in multi-user application environments such as Quick Books where synchronized writes are necessary to keep files in sync. The Force CIFS filename case-sensitivity option provides substantial performance improvement when you access CIFS shares when many files are being copied; however, before enabling this option, understand the ramifications.
Since Windows runs in case-insensitive mode, one side-effect of enabling this option is that two file names with different cases (for example, ABC and abc) appear as two files but, when you open one file, the other file might actually open. Another effect of this option is that, in Explorer, you now need to enter the exact case for search strings for the Find option (that is, searching for abc no longer returns file ABC). Some Windows applications that assume case-insensitive operations (for example, BackupExec) may have problems. Do not enable this option if you have clients accessing the NAS running Windows NT/95 or earlier.

The Enable fast USB disk writes option speeds up USB write access by allowing access to the USB device in asynchronous mode. If you enable this option, do not remove the USB device without properly unmounting it. Failure to do so can compromise data integrity on the device.
Adding a UPS for Performance Adding a UPS to the NAS is an easy way to protect against power failures, but as mentioned in Performance on page 1-56, a UPS can also safely allow for a more aggressive performance setting. Simply connect the NAS power cable to the UPS, and connect the UPS USB monitoring cable between the UPS and the NAS. The UPS is detected automatically and shows up in the Status bar. You can move the mouse pointer over the UPS LED icon to display the current UPS information and battery life.

Figure 1-62

Note: Note that alert notification and automatic system optimization is available only with UPS that utilizes a USB monitoring interface. You are notified by e-mail whenever the status of the UPS changes; for example, when a power failure forces the UPS to be in battery mode or when the battery is low. When the battery is low, the NAS device automatically shuts down safely. Make sure to adjust the optimization settings in the Performance screen if you wish to take advantage of the available options.

1-58 v1.0, October 2007

Language
The Language Setting screen offers the option of setting the ReadyNAS device to the appropriate character set for file names.

Figure 1-63

For example, selecting Japanese allows you to share files with Japanese names in Windows Explorer.

Figure 1-64

It is best to select the appropriate language based on the region where the device will be operated.
Note: This option does not set the web browser language displaybrowser settings must be done using the browser language option. If you wish, you can select the Allow Unicode for user, group and share names check box to allow for greater flexibility in non-English speaking regions. This option, once selected, cannot be reversed. Note: HTTP and WebDAV access do not work with Unicode user names. Other restrictions might exist. If your FTP client uses different character encoding from the NAS character encoding specified in Unicode, the NAS FTP server will convert it if you select the Enable character encoding conversion for FTP clients check box.
