Safety Precautions Keep the area around the BizNAS clean and free of clutter. Never place the BizNAS near water. Take care to avoid spilling any liquid on the unit. Place the BizNAS desktop in an area with adequate ventilation. For example, do not place the BizNAS in a bookcase or closed cabinet where air flow can be blocked. When installing the BizNAS R400 series in a rack, ensure that the amount of air flow required for safe operation of the equipment is not compromised. Do not move the BizNAS when it is powered on to avoid damage to the installed disk drives. Place the BizNAS in a stable environment that does not experience sudden changes in temperature or humidity. To reduce the risk of electric shock, do not remove the chassis cover from the BizNAS. Doing so will void the warranty. Electrical Safety Precautions When handling or installing disk drives into the BizNAS, take care with the following precautions: Use a grounded wrist strap designed to prevent static discharge. Discharge static electricity from your body by touching a known grounded surface, such as a computer s metal chassis. Keep all components in their antistatic bags until ready for use

Connect Network and Power Cables Before you begin, obtain the power cord that is appropriate for your geographic region and the ethernet cable from the accessories kit that shipped with your unit. To connect the ethernet and power cables: Connect the ethernet cable to an ethernet port on the BizNAS. Connect the other end of the cable to an ethernet port on a switch or router. Connect the power cable that is appropriate to your geographic region to the BizNAS. Plug the power cord into an electrical outlet. Turn the power on. Next Step: Discover your NAS Discover your NAS The BizNAS D400/R400 series retrieves its IP address and other network addressing automatically via DHCP. After you have accessed the BizNAS Information Center, you can change to the IP address, if desired (see static network addressing). Note: If your network does not use DHCP, or if your router does not have access to the Internet, refer to the Tandberg Data Knowledge Base for alternate discovery methods. To discover your NAS: 1. From a computer on the same network as the BizNAS, go to 2. Type your BizNAS registration code. The registration code is a 4-character code that is located on the top cover of the R400 unit, or on the back panel of the D400 unit. The registration code is also printed on the Quick Start Guide that shipped with your unit. See a picture of registration code locations here. 3. Click Submit

Click the BizNAS IP address link in step 3 of the NAS Discovery page to launch the Tandberg Data BizNAS Information Center. Next step: Set up your NAS. Basic NAS Set Up The prompts on the BizNAS Information Center home page will guide you through the basic NAS setup process. Click on the topics below for information about each step. Basic NAS set up involves these steps: 1. Configuring disks. 2. Creating storage volumes. 3. Creating shared folders. 4. Setting the system time. 5. Configuring network settings. 6. Configuring notification settings. 7. Setting the administrator password. Where to Go for Support Visit the Support section at for the following: Knowledge base articles Troubleshooting information Product documentation Software updates Product warranty and registration and phone technical support About Disk Configuration Options The BizNAS provides two options for disk configuration: typical and advanced. Typical disk configuration offers three predefined storage levels based on your preference for data protection, or fault tolerance Fault tolerance relates to the storage system's ability to recover data if one or more disks fail. For example, a fault tolerance of 1 means that the system can restore all data if one disk fails. A fault tolerance of 2 means that all - 8 -

9 data can be restored if two disks fail.. Advanced disk configuration provides greater flexibility by allowing you to specify a RAID storage level based on your storage needs and the number of disks installed in your system. Note: Choose Advanced only if you are very familiar with RAID levels and storage management tasks. More information about Typical disk options The following table describes the three pre-defined choices available for typical disk configuration. Note: The default option allows for data recovery if one disk fails (provided you have two or more disks installed). Number of Disks in System Data Protection Configuration Best Choice if... two disks can fail without data loss RAID 6 Data availability and protection are your highest priorities. This option has less available storage capacity because up to two disks can fail. 4 one disk can fail without data loss RAID 5 You want a balance between having some data protection and adequate storage capacity. no protection against data loss JBOD Storage capacity is your highest priority. You are not concerned about data loss if one or more disks fail. 3 one disk can fail without data loss no protection against data loss RAID 5 JBOD You want a balance between having some data protection and adequate storage capacity. Storage capacity is your highest priority. You are not concerned about data loss if one or more disks fail. 2 one disk can fail without data loss RAID 1 Data protection is more important than storage capacity. With two disk installed, RAID 1 mirrors an exact copy of your data on the second disk. Data is available if one disk fails, but storage capacity is 50 percent. no protection against data loss JBOD Storage capacity is your highest priority. You are not concerned about data loss if one or more disks fail. 1 no protection against data loss Single Disk JBOD You want the flexibility to upgrade to a RAID configuration when you add new disks to the system. This is the default option if you have only one disk installed. With JBOD, you cannot upgrade to a RAID configuration when you add more disks to your system. You can only expand your - 9 -

10 Number of Disks in System Data Protection Configuration Best Choice if... JBOD configuration when adding new disks. More Information about Advanced disk options Advanced disk options allow you to specify a RAID storage level based on your storage needs and the number of disks installed in your system. When determining which RAID level to choose, there are three main points to consider: 1. Storage capacity. What is your preference and need for available disk space? Is data protection more important at the expense of less storage capacity, or is storage capacity more important than the potential loss of data? 2. Data Protection. What is your comfort level in regards to data loss and data availability if one or more disks fail? 3. I/O Performance. What are your application workload requirements? Are you running database applications, which require higher I/O and data throughput performance? The following table describes the RAID level options available with advanced disk configuration. RAID Level Single Disk JBOD Number of Disks in System Data Protection 1 no protection against data loss 1 to 4 disks. no protection against data loss Description Single Disk is the default option if you have only one disk installed. Leave this option selected if you want to upgrade to a RAID configuration in the future when adding new disks to the system. JBOD is not a true RAID level, but a set of combined disks that appear as one logical disk. JBOD provides none of the data protection or performance advantages that RAID offers. However, if storage capacity is your only priority, JBOD can be a good choice, especially if you have disks of varying storage capacity sizes. Advantage: Allows the system to use the combined capacity of different-sized disks. Disadvantage: Zero protection against data loss if a disk fails. Slower I/O performance than RAID 0. You cannot upgrade a JBOD configuration to a RAID configuration when adding new disks

11 RAID Level RAID 0 Number of Disks in System Requires a minimum of 2 disks. Data Protection no protection against data loss Description RAID 0 stripes data evenly across all disks. It provides the best I/O (read/write) performance of all the RAID types, but offers no protection against disk failures. RAID 0 is a good choice if fast data throughput is your only priority. Storage capacity is dependent on the disk with the least amount of disk space. For example, if you have a mix of 1 and 2 TB disks, your data capacity is limited to 1 TB across all disks. If one disk fails, the data on the healthy disks is also lost because data is written ("striped") evenly across all disks. Advantage: Fast I/O performance and greatest amount of storage utilization, provided that all disks are of the same capacity. Disadvantage: Zero protection against data loss if a disk fails. Storage capacity is dependent on the disk with the least amount of disk space. RAID 1 Requires a minimum of 2 disks. All but 1 disk can fail without data loss RAID 1 provides a mirrored copy of data onto all disks and is a good choice if data protection and availability are more important than storage capacity. Because RAID 1 has better read performance than write performance, it can be a good choice for database applications as many database servers have a higher ratio of read requests to write requests. Advantage: Excellent data protection and data availability if a disk fails. Excellent Read performance and good write performance. Disadvantage: Data capacity is limited to the size of one disk, since all disks store the same data. RAID 5 Requires a minimum of 3 disks. 1 disk can fail without data loss RAID 5 offers data striping across all disks plus parity. Parity means that each disk contains a redundant block of the striped data. If a disk fails, the data can be recovered from the parity blocks, which exist on the remaining healthy drives. RAID 5 is a standard selection and provides a good balance of data protection and storage capacity needs. Advantage: RAID 5 provides greater storage capacity than mirroring options but still has excellent data availability and protection if a disk fails. Disadvantage: Rebuilding the data to a replacement disk may take a long time. If a second disk fails during the rebuild, you may lose all data. Also, performance is lower than RAID 0. RAID 5 + spare Requires 4 disks. 1 disk can fail without data loss RAID 5 + spare provides striping and parity across three disks. The fourth disk is used as a spare. If a disk fails, the data is rebuilt onto the spare disk as soon as the drive fails

12 RAID Level Number of Disks in System Data Protection Description Advantage: RAID 5 + spare provides a balance of data protection and capacity with good I/O performance. Disadvantage: Rebuilding the data onto the spare disk can greatly reduce data availability. If a second disk fails during the rebuild, you may lose all data. RAID 6 Requires 4 disks. 2 disks can fail without data loss RAID 6 provides greater data protection because up to two disks can fail with losing data. RAID 6 is similar to RAID 5 in that it uses both striping and parity, except that RAID 6 uses two parity blocks instead of one parity block for fault tolerance. RAID 6 is an excellent choice if data protection is of the utmost importance. Advantage: If you are worried about a second drive failing during a lengthy rebuild process, RAID 6 offers security in knowing that a second drive can fail and your data is still recoverable. Disadvantage: RAID 6 has much slower rebuild times and can have poor write performance, although read performance is good. Storage capacity is less than RAID 5. RAID 10 (or RAID 1+0) Requires 4 disks. 1 disk can fail without data loss RAID 10 (also known as RAID 1 + 0), combines attributes of RAID 1 (mirroring) and RAID 0 (striping), by striping data across two mirrored sets of disks. RAID 10 is a good choice if data protection is more important than storage capacity. Advantage: RAID 10 offers faster rebuild times in the event of a disk failure. RAID 10 provides good I/O performance and data protection. Disadvantage: Storage capacity is reduced to 50-percent capacity because of the dual mirrored sets. Configuring Disks To configure disks in your BizNAS, do the following: Select Storage from the BizNAS Information Center main menu, then select the Disks tab. Choose either Typical or Advanced for disk configuration

13 Select a storage configuration, click OK. The Add Disk Verification dialog opens to confirm your choice. Click OK again. The disk configuration process begins. Configuring disks may take several hours depending on the capacity and configuration. When the configuration process completes, the system reboots; the Disks page automatically refreshes, and the disk status reports "Ready." Note: You can add storage volumes and create shared folders while the system is configuring disks. Upgrading RAID These instructions refer to adding a disk to a healthy disk configuration. If you need to add a disk to a degraded RAID configuration, see Rebuilding RAID. To add one or more disks to a single-disk system, RAID 1, or RAID 5 configuration: Install the disk into the drive tray and insert the tray back into the empty slot. The BizNAS Information Center displays the Disks page with the message. "New Disks Detected." Click Add Disks. Choose the RAID type. The dialog window displays the RAID options that are available depending on how the number of disks you are installing. See Upgrading RAID Options for possible configurations. See About Disk Options for more information about RAID types. Click OK. The Add Disk Verification dialog opens to confirm your choice Click OK again

14 The disk configuration process begins. During this time, your BizNAS system will be available, but you may notice decreased I/O performance. A progress bar will display the approximate amount of time left in the configuration process. Upgrading RAID Options The following table lists possible RAID upgrades when adding one or more new disks to the BizNAS. Note: The choices for a new RAID type depends on the number of disks in your system. See About Disk Options for more information about RAID types. Existing Configuration New RAID Type Choices Single Disk RAID 1, RAID 5, RAID 5 + spare, RAID 6 RAID 1 RAID 1, RAID 5, RAID 5 + spare, RAID 6 RAID 5 RAID 5, RAID 5 + spare, RAID 6 Note: With JBOD and RAID 0 configurations, you cannot upgrade to another RAID type. With JBOD, you can only expand your existing JBOD configuration. With RAID 0, you cannot expand your existing RAID 0 configuration. If you want to change your system from JBOD or RAID 0 to a new RAID configuration, you must do the following: Backup your data to an external disk. Remove the existing configuration in the BizNAS Information Center. Install the new disk into the BizNAS. Re-configure the disks with the new RAID configuration. Rebuild your data from the external disk

15 Rebuilding a Degraded RAID Configuration These instructions refer to adding a disk to a degraded RAID configuration. If you are adding a new disk to a healthy system, see Upgrading RAID. Note: If you have a RAID configuration that uses a hot spare, such as RAID 5 + spare, or RAID 1 + spare, the system will automatically begin to rebuild data from your degraded RAID onto the spare disk. Therefore, you do not need to add a new disk to begin the RAID rebuild process. Once the system has finished rebuilding the RAID, remove the failed disk and add a healthy disk to replace the spare. To add a disk to a degraded RAID configuration: 1. Remove the failed disk from the BizNAS. 2. Install the new disk into the drive tray and insert the disk tray back into the empty slot. The BizNASwill automatically rebuild the RAID with the new disk inserted. During this time, your BizNAS will be available, but you may notice decreased I/O performance. A progress bar will display the approximate amount of time needed to complete the rebuild process. Scheduling a RAID Consistency Check You can schedule a RAID consistency check as part of your general maintenance tasks or run a check immediately if you suspect a problem.the disk status must be in a Ready state to run a RAID check. Note: RAID checks are not available for JBOD or RAID 0 disk configurations. To run a RAID check: 1. Select Storage from the BizNAS Information Center main menu, then select the Disks tab. 2. Click the Check RAID button

16 The Check RAID dialog opens. 3. Schedule a RAID check by selecting the frequency, day, and time, or select the "Run Check Now" checkbox. See RAID Consistency Scheduling Options for more information. 4. Click OK to confirm. You can use the BizNASwhile the check is in progress, but you may notice decreased I/O performance. A progress bar will display the approximate amount of time left in the configuration process.the system generates an information alert if the check passes successfully. If the check fails, the system generates an error alert. RAID Consistency Scheduling Options The following table describes the scheduling options available when you create a RAID consistency check. Check RAID Schedule Option Description You can set your check operation to one of the following job frequencies: Frequency Not Scheduled the RAID check does not run on a schedule. Daily the RAID check runs every day at the selected time. Weekly the RAID check runs once per week at the selected day of the week and time. End of Month the RAID check runs on the last day of the month at the selected time. Day/Time Run Backup Now Use the Day field to specify the day of the week or day of the month to run the RAID check, depending on the selected frequency. Use the Time field to specify the time of day to run the RAID check, depending on the selected frequency. Select this checkbox to run a one-time, non-recurring RAID check immediately

17 Removing your RAID Configuration You can remove your current BizNASdisk configuration if necessary. Be aware that when you remove the RAID configuration all your volumes, shares, and data are permanently erased. To remove the RAID configuration: 1. Select Storage from the BizNAS Information Center main menu, then select the Disks tab. 2. Click Remove. The Remove Configuration dialog opens. 3. Select the Yes, please permanently delete all data on disks check box. 4. Click OK. Identifying Disks If you need to identify which physical disk corresponds to the slot listed on the Disks page, you can blink the LED for that disk. To blink the LED for a disk: 1. Select Storage from the BizNAS Information Center main menu, then select the Disks tab. 2. Click the Action button for the disk you want to identify. 3. Select Identify from the pop-up menu.

Disk Status Ready Configuring Not Configured Empty Warning Description A healthy disk that has been configured for RAID or JBOD. The disk is in the process of being added to a RAID configuration. A healthy disk that is physically in a disk slot but has not yet been configured for RAID or JBOD. No disk is physically in the slot. The S.M.A.R.T. S.M.A.R.T. stands for Self-Monitoring Analysis and Reporting Technology. It is a diagnostic method used to provide advanced warning of potential drive failure. temperature data indicates a problem with the disk. An alert is also generated with this warning. Error The disk has failed and must be replaced. An alert is also generated with a disk error status. Disk Health To access Disk Health: From the BizNAS Information Center main menu, select Storage, then select the Disks tab. The following table lists values that may appear in the Disk Health column. Disk Health Value OK Disk May Fail Description The S.M.A.R.T. S.M.A.R.T. stands for Self-Monitoring Analysis and Reporting Technology. It is a diagnostic method used to provide advanced warning of potential drive failure. overall-health self-assessment test passed. This disk is healthy. The S.M.A.R.T. overall-health self-assessment test did not pass. This disk should be replaced as soon as possible

19 Disk Errors The following types of disk errors are reported with the BizNAS. Disk configuration degraded. The RAID is still functional but you should remove the failed disk and rebuild the RAID as soon as possible. RAID failure. Depending on your RAID configuration, this error state indicates that one or more disks have failed in your system to the point where data is no longer protected or available. For example, if your system is set to RAID 0, the RAID Failure error occurs if one disk failed. If your system is set to RAID 1, RAID 5, or RAID 10, the RAID failure error occurs if two disks have failed. About Volumes If you are adding a volume for the first time, The BizNAS provides two options for volume setup: typical and advanced. See the table below to help you choose the best setup for your environment. Volume Setup Description Best Choice If... Typical Typical volume setup allows you to create a single file system volume to use for your file sharing needs. If you add disks at a later time, you can choose to create another volume or expand the capacity of your existing volume. You seek basic file sharing storage for Windows, Mac, or Linux systems. You know you will never have a need to use iscsi block storage. Advanced Advanced volume setup allows you to create both file system volumes and iscsi block storage volumes. You can partition storage into several file system and/or iscsi block volumes. You want the flexibility to choose file system and iscsi block volumes for your network.you require higher performance storage for a database server, virtual machine, or MS Exchange server

20 File system vs. iscsi block storage volumes Below is an overview of the differences between file system volumes and iscsi block volumes. File System Provides file sharing of data on Windows, Mac, and Linux systems. Simpler to manage. Allows file sharing access via FTP. Because File System storage is easier to manage, it is a good choice for normal use. iscsi Block-Level Appears as a direct-attached hard drive to host systems targeting the iscsi LUN. More complex to manage. Provides higher performance than file system volumes. Because iscsi block storage offers higher performance, it's a good choice for database servers, virtual machines, and MS Exchange servers.

You can enable file sharing for Windows, Linux, and Macintosh host operating systems on your network. The file sharing protocols that the BizNAS supports are: Common Internet File System (CIFS) protocol for Windows-based systems. Network File System (NFS) protocol for Unix/Linux-based systems. Apple Filing Protocol (AFP) for Macintosh-based systems. The BizNASalso supports Apple Time Machine when setting up shared folders

25 Note: You can also access shared folders via File Transfer Protocol (FTP). For more information about setting FTP access, see Enabling FTP. By default, Windows shared folders are set to public, which allows access to all users on your network. Expand the links below for more information about a specific file sharing protocol. More information about Windows (CIFS) There are three options for setting Windows file sharing access: Public Joining a Windows Workgroup Joining a Windows Domain File Sharing Option Description Best Choice If... Public All Windows users on your network have unrestricted read/write access to the shared folder. You have no need to restrict user access to shared folders. Windows Workgroup A Windows workgroup is typically a small group (less than 20) of computers that reside on the same local network. Joining the BizNAS to a Windows workgroup is a simpler, less expensive method of restricting network folder access. A workgroup does not require a domain controller A dedicated server that is used solely for security authentication requests within a Windows Server domain. It is a server on a Microsoft Windows or Windows NT network that is responsible for allowing host access to Windows domain resources. to restrict user access. Users and Groups are set up in the BizNAS Information Center. For more information about joining the BizNASto a Windows workgroup, see Joining a Windows Workgroup or Domain. Your network does not have a domain controller, but you still need to restrict shared folder access to different groups and users. For best practices, see About Configuring Windows Access. Note: If you want to password-protect your shared folders, you must set a password for the BizNAS admin user. Once you have set an admin password,

26 File Sharing Option Description Best Choice If... de-select the checkbox titled "Public Share accessible without password" to enable password-protection. Windows Domain A Windows domain controller uses Windows Active Directory to authorize user access to network folders. Typically, companies with networks larger than 10 to 20 computers use a domain controller to manage users access to shared directories.for more information about joining the BizNASto a Windows domain, see Joining a Windows WorkGroup or Domain. Your network includes a domain controller. You manage user and group access via Windows Active Directory. More information about NFS For best practices, see About Configuring Windows Access. The Network File System protocol is used to enable file sharing in Unix/Linux environments. When you enable NFS file sharing in the BizNAS Information Center, the default option is configured for root squashing, which allows all host systems access to network shared folders. Note: If you want to restrict user/host access to shared folders, you can set NFS privileges after you have created the shared folder. For NFSv3 clients, the shared folder will be exported with the prefix /nfs. For example, a shared folder named "TestShare" will use the share path /nfs/testshare. Use the following mount command as an example when mounting this shared folder from a Linux client using NFSv3: mount t nfs BizNASNameOrIP:/nfs/TestShare /path/to/mount Replace BizNASNameOrIP with the name or IP address of the BizNAS with the exported NFS share. Replace TestShare with the name of the shared folder exported via NFS. Replace /path/to/mount with the path to the mountpoint for this NFS directory. NFSv3 clients will also see an exported shared folder /nfs from BizNAS as displayed by the showmount command. NFSv3 clients should not map this shared folder; this shared folder is present to support NFSv4 clients only

27 For NFSv4 clients, all shared folders exported by the BizNAS can be reached through the /nfs pseudofilesystem as a root directory. Use the following mount command as an example when mounting all NFS shared folders from the BizNAS using NFSv4: mount t nfs4 BizNASNameOrIP:/ /path/to/mount Replace BizNASNameOrIP with the name or IP address of the BizNAS with the exported NFS share. Replace /path/to/mount with the path to the mountpoint for the NFS server. All NFS shared folders hosted by this BizNAS are displayed under the /path/to/mount directory when the NFSv4 mount command completes with success. More information about Macintosh (AFP) When you enable Mac File Sharing for a shared folder in the BizNAS Information Center, the system limits read/write access to all BizNAS users and groups. To configure user access, add users and groups in the BizNAS Information Center. Note: If you have not added any users, you can access shared folders from a Mac computer using the default user name "admin" and password "admin." To allow Time Machine to back up a Mac computer to your shared folder, select the Enable Time Machine checkbox when you create the shared folder. Creating Shared Folders You must have at least one storage volume created before you can create a shared folder. Note: It is recommended that you set up separate shared folders for Windows (CIFS) user access and NFS user access. Enabling CIFS and NFS access on the same shared folder may cause file locking and permission problems. To create a shared folder: 1. Select Storage from the BizNAS Information Center main menu, then select the Shared Folders tab. 2. Click +Add

28 The Add Shared Folder dialog window opens. 3. Type a name for the shared folder. Special characters are allowed. 4. Type a description, if desired. 5. Select the volume that the shared folder will use. 6. Enable the file sharing protocols that will access the shared folder. Enabling the file protocols from this dialog allows all users on the network access to the shared folder. See About Shared Folders for information on restricting user access. 7. Click OK. Modifying Shared Folders You can edit, delete, set NFS privileges, and change group and user permissions using the Action Editing Shared Folders To edit a shared folder: button that is available for each shared folder. 1. Select Storage from the BizNAS Information Center main menu, then select the Shared Folders tab. 2. Click the Action button located on the shared folder row that you want to edit. 3. Select Edit from the drop-down menu. The Edit Shared Folder dialog window opens. 4. Make your desired changes to the name, description, or file sharing access. Note that you cannot move a shared folder to another volume. 5. Click OK. Deleting Shared Folders To delete a shared folder: 1. Select Storage from the BizNAS Information Center main menu, then select the Shared Folders tab. 2. Click the Action button located on the shared folder row that you want to delete. 3. Select Delete from the drop-down menu. 4. Click OK to confirm that you want to delete the shared folder

29 Setting NFS Privileges Setting Group Permissions from Shared Folders Setting User Permissions from Shared Folders About Remote Shared Folders You can connect to folders on your network that have been made available for sharing through CIFS (Common Internet File System). Once a remote shared folder has been connected, you can access it through the BizNASFile Manager and use it as the source or destination of a backup job. Adding a Remote Shared Folder To add a remote shared folder: 1. Select Storage from the BizNAS Information Center main menu, then select the Remote Shares tab. 2. Click +Add. The CIFS Shared Folder dialog opens 3. Type the host name or the IP address where the shared folder resides. 4. Type the user name and password, if required to access the shared folder. 5. Click Connect. The BizNAS connects to the specified host with the credentials provided. If the connection is successful, the shared folders available on the host are shown in the CIFS Network Folder menu. 6. Either select a folder from the CIFS Network Folder menu or type the name of a hidden folder that resides on the host. 7. Click OK. Deleting a Remote Shared Folder To delete a remote shared folder: 1. Select Storage from the BizNAS Information Center main menu, then select the Remote Shares tab. 2. Click the Action button located on the shared folder row that you want to delete. 3. Select Delete from the drop-down menu. 4. Click OK to confirm

30 Disconnecting a Remote Shared Folder You can disconnect a remote shared folder temporarily, but you cannot delete the connection. You can reconnect the shared folder later without re-entering user credentials. To disconnect a remote shared folder: 1.

31 Setting NFS Privileges When you enable NFS file sharing in the BizNAS Information Center, the default option is configured for root squashing, which allows all host systems access to network shared folders as an admin user. If you want to restrict user/host access to shared folders, you can modify the exportfs configuration file from the BizNAS Information Center. Note: Configuring the exportfs file requires that you have knowledge of proper syntax rules and commands. For detailed information on syntax and commands, see the exports(5) Linux man page. To set NFS privileges: 1. Select Storage from the BizNAS Information Center main menu, then select the Shared Folders tab. 2. Click the Action button located on the shared folder row that you want set privileges for. 3. Select NFS Privileges from the pop-up menu. The NFS Settings dialog window opens. A list of the current uid/gid values that are set up in the BizNAS Information Center is displayed. The anonuid and anongid values can be used to map accesses from all users to specific user ID's. 4. Make your desired changes to the exportfs configuration field. See the section below for some basic syntax rules to follow. Refer to the exportfs man pages for more detailed information. 5. Click OK. The exportfs line will be placed directly into the /etc/exportfs file immediately after the path to the share. Configuring the Exportfs File Follow these syntax rules when you configure the exportfs configuration field: Use the format host(settings), where host refers to the host to which the export is being shared and settings refers to the access settings to be used for host (such as, read only, root squash, and the uid/gid values for the host). The access settings for each of the hosts must be placed in parentheses directly after the host identifier, without any spaces separating the host and the first parenthesis

32 Separate multiple hosts, along with the specific settings for each host, with a space. For example: host1(settings1) host2(settings2) host3(settings3) The exportfs configuration field displays the current NFS user configuration mapping scheme. For example, when you enable NFS file sharing on a shared folder, the default exportfs configuration will look similar to this: *(rw,all_squash,anonuid=1100,anongid=999) The "*" refers to all hosts on the network. The "rw" refers to read/write access. The "all_squash" refers to root squashing is enabled for all hosts. The "anonuid" value of 1100 refers to the user id for the built-in BizNAS admin user. The "anongid" value of 999 refers to the group id for the built-in BizNAS administrators group. Note: You may need to update your exportfs permissions if user/group accounts are added or deleted. Example exportfs configurations: Always access as user admin from any IP, read only: *(ro,all_squash,anonuid=1100,anongid=999) Always access as user admin from specific IP, read and write:

33 (rw,all_squash,anonuid=1100,anongid=999) exports(5) - Linux man page Exports NFS Server Export Table Description The file /etc/exports contains a table of local physical file systems on an NFS server that are accessible to NFS clients. The contents of the file are maintained by the server's system administrator. Each file system in this table has a list of options and an access control list. The table is used by exportfs(8) to give information to mountd(8). The file format is similar to the SunOS exports file. Each line contains an export point and a whitespace-separated list of clients allowed to mount the file system at that point. Each listed client may be immediately followed by a parenthesized, comma-separated list of export options for that client. No whitespace is permitted between a client and its option list. Also, each line may have one or more specifications for default options after the path name, in the form of a dash ("-") followed by an option list. The option list is used for all subsequent exports on that line only. Blank lines are ignored. A pound sign ("#") introduces a comment to the end of the line. Entries may be continued across newlines using a backslash. If an export name contains spaces it should be quoted using double quotes. You can also specify spaces or other unusual character in the export name using a backslash followed by the character code as three octal digits. To apply changes to this file, run exportfs-ra or restart the NFS server. Machine Name Formats NFS clients may be specified in a number of ways: Single host This is the most common format. You may specify a host either by an abbreviated name recognized be the resolver, the fully qualified domain name, or an IP address. Netgroups
