Stripe Group Movement accomplishes two purposes: moving data files between stripe groups, and freeing stripe groups so they can be removed from an existing StorNext file system.
Chapter 6 Managing the File System Checking the File System 4 Mark source stripe groups as down. (See Modifying a Stripe Group on page 116.) Checking the File System Before you perform either File System Expansion or Stripe Group Movement, you must first perform a check on the file system you plan to use for these features. This operation could take a significant amount of time depending on the size of the file system, so plan accordingly. Use the following procedure to perform a file system check.
Chapter 6 Managing the File System Checking the File System 3 If desired, select the Check Read Only option if you want to perform the file system check in read-only mode. Note: If the file system you select is currently started and mounted, the check will be automatically performed in read-only mode. In read-only mode on a live file system (started and mounted,) you could receive false errors. 4 When you are ready to proceed with the check on the selected file system, click Apply.
Chapter 6 Managing the File System Performing File System Expansion Figure 96 Check File System Status Screen Performing File System Expansion In practical terms, expanding an existing file system means allocating additional storage to that file system.

Here is an overview of the steps required to enable File System Expansion: 1.
Chapter 6 Managing the File System Performing File System Expansion Note: During File System Expansion the file system is shut down. After expansion you must perform a new metadata dump runs after the file system is updated. For managed file systems, the File System Expansion wizard includes an option for you to run the metadump automatically, or you can do it separately from the wizard. As a final part of the File System Expansion process, StorNext restarts the file system.

Chapter 10 Managing Storage Disks Cleaning a Storage Disk Cleaning a Storage Disk The cleaning process scans the storage disk and removes inactive files that have not been accessed since the endtime, and orphaned file copies (i.e., archive copies on the file system disk,). Using this process helps prevent the inactive information from growing to an unmanageable size. This process does not affect current file versions on the media.
Chapter 10 Managing Storage Disks Cleaning a Storage Disk Note: StorNext User’s Guide When you clean a deduplication-enabled storage disk, blocklets are not immediately freed from the associated blockpool. The unused blocklets will be freed when the weekly clninfo schedule is run. If you want to immediately free blocklets, you can run the fsclean -b command from the command line.
Chapter 11 11 Data Migration Management This chapter describes how to use StorNext to manage data. This chapter covers these topics: • Policy Classes and Relationships • Adding a Storage Policy • Modifying a Policy Class • Deleting a Policy Class • Applying a Policy Class This chapter includes procedures executed from the command line. Before initially executing any StorNext command line programs, you must first source either the .profile or the .
Chapter 11 Data Migration Management Policy Classes and Relationships Policy Classes and Relationships A policy class defines how files will be managed in a directory and subdirectories.
Chapter 11 Data Migration Management Adding a Storage Policy remains on disk after data blocks are freed during policy management or space management. Disk-to-Disk Relocation11 Disk-to-Disk relocation allows you to move data from one set of disks (disk stripe group) to another without affecting the file name space. You can perform this procedure only if you have the full StorNext suite. (Customers with StorNext File System only cannot perform this procedure.
Chapter 11 Data Migration Management Adding a Storage Policy Note: You cannot create a policy class when a client is NFS mounted to an active Stornext file system. When you create a policy class, the StorNext GUI executes the command fsaddrelation. The fsaddrelation command fails if the specified directory is not empty and the associated file system is busy. When a client is NFS mounted, the NFS daemon holds a reference in the directory. Consequently, the unmount fails, aborting the fsaddrelation process.

Chapter 14 14 Customer Assistance More information about this product is available on the Quantum Service and Support website at www.quantum.com/ServiceandSupport. The Quantum Service and Support website contains a collection of information, including answers to frequently asked questions (FAQs). You can also access software, firmware, and drivers through this site.
Appendix A HA Failover A StorNext is designed to be a resilient data management solution. StorNext supports operation in degraded mode and provides functionality to guarantee data protection in the event of a storage device failure or total site outage. For certain environments though, additional protection is required to deliver a higher level of availability. To meet these demands, StorNext includes MetaData Controller (MDC) failover.
shuts down a degraded MDC and then reboots it so that, on recovery, it becomes the standby MDC in the event future MDC failover is required. While other methods of failover are available, such as quorums, STONITH is the only widely acknowledged method of reliable failover control - especially for software that runs on multiple operating systems.
Appendix B Using The Command Line Interface B Quantum recommends using the GUI to complete most StorNext tasks, but there may be situations where you need to use the command line interface instead.
Labeling Disk Devices Labeling Disk Devices Each drive used by SNFS must be labeled. A new drive only needs to be labeled one time. A drive can be labeled from any StorNext server or client that has a Fibre Channel (FC) connection to the drive. Use this procedure to label a disk device using CLI. Caution: The process of disk labeling re-partitions the drives. If you select an incorrect drive, you may lose data. Also, it’s a good practice to save a copy of your labels file.
Modifying Global Settings The created file displays an entry for disks located by the /usr/cvfs/ bin/cvlabel command. CvfsDisk_UNKNOWN /dev/sdb # host 4 lun 1 sectors 639570752 ... CvfsDisk_UNKNOWN /dev/sdc # host 4 lun 2 sectors 639570752 ... CvfsDisk_UNKNOWN /dev/sdd # host 4 lun 3 sectors 639570752 ... Caution: Identify any drives that already contain a recognized Volume Type. Do not write a label to these drives or you may lose data.
Modifying Global Settings For most of these parameters, the only thing necessary for the modified parameter to take effect is to restart the File System Manager (FSM). However, the following parameters require that the file system be fully re-initialized (which will result in data loss,) before they take effect: • FSBlockSize • WindowsSecurity If a parameter change requires file system re-initialization, the system notifies the administrator in the system log.
Making a File System 4 Make the appropriate edits to the configuration file. 5 Restart the file system.
Starting and Stopping SNFS 2 Make sure you are the root user by typing the following: cd / 3 Unmount the system by typing the following: umount where the is where you have mounted the SNFS. For example: umount /stornext/snfs1 4 Stop the system by typing the following: /usr/cvfs/bin/cvadmin snadmin> stop where the is the name of the file system to be stopped.
Unmounting or Mounting a File System /usr/cvfs/bin/cvadmin snadmin> select snadmin> stop Unmounting or Mounting a File System To unmount a file system using the CLI, follow these steps: 1 Change the login user to root. Type: cd / 2 Unmount the system. Type: umount where the is where you are mounting the SNFS. For example: umount /stornext/snfs1 To mount a file system using the CLI, follow these steps: 1 Change the login user to root.
Creating a File System Server Creating a File System Server The follow procedure describes how to create a file system server using the CLI. Before initially executing any SNFS command line programs, you are required to source either the .profile or the .cshrc file. This updates the user environment with the SNFS environment variables. • If you are running sh, ksh, or bash, type: . /usr/adic/.profile • For all other shells, type: source /usr/adic/.
Creating a File System Server 4 Label the FC drives by typing the following: /usr/cvfs/bin/cvlabel /user/cvfs/config/cvlabels 5 Copy the example file system configuration file to the config directory by typing the following: cp /usr/cvfs/examples/example.cfg /usr/cvfs/config/ .cfg 6 Edit the StorNext configuration file you just created to include the desired settings, disks, and stripe groups.
Adding a File System Client 16 Restart the file system. Type: /usr/cvfs/bin/cvadmin snadmin> start snadmin> activate snadmin> select snadmin> show snadmin> who snadmin> quit 17 Mount the system by typing the following: mount -t cvfs For example: mount -t cvfs snfs1 /stornext/snfs1 Adding a File System Client Use this procedure to add a file system client using the CLI.
Configuring a Stripe Group Configuring a Stripe Group Following is an example of a stripe group configuration in a file system configuration file. You can use a text editor to modify any of these variables. The values shown might not be representative of typical definitions.
Adding an Affinity Adding an Affinity This procedure lets you set stripe group affinities for assigning file locations to a specific file system stripe group. All subsequent allocations to a file that have been assigned a valid stripe group affinity will occur on the specified stripe group. Affinities may also be assigned to files and directories using the cvaffinity command. For more information about the cvaffinity command, refer to the CLI Reference Guide.
Adding an Affinity 4 Locate the stripe group section and select the stripe group to which you want to add the affinity.
Creating a Disk-to-Disk Policy Class Affinity data1aff StripeBreadth 512 Node CvfsDisk2 0 Node CvfsDisk3 1 6 Save and close the configuration file.
Creating a Disk-to-Disk Policy Class source /usr/adic/.cshrc Use the fsaddclass command to create a new policy class by typing the following: /usr/adic/TSM/exec/fsaddclass -a -i For example: /usr/adic/TSM/exec/fsaddclass dtdclass1 -a Aff1 Aff2 -i 1 The list of affinities includes the same affinities that were defined through the GUI.
Enabling Stub File Support You can also use metacharacters when defining the file name parameter. For example: /usr/adic/TSM/exec/fsrelocate -a Aff2 /stornext/snfs1/relocate/* Enabling Stub File Support The following file system commands have been enhanced to support StorNext’s Stub File feature: • fsaddclass • fsmodclass • fschfiat • fschdiat Specifically, a -S stubsize option has been added to each command. This option allows you to specify the desired file stub size in kilobytes.
Managing Storage Disks with Deduplication Enabled Managing Storage Disks with Deduplication Enabled Quantum recommends using the StorNext GUI to manage the storage disk deduplication feature, but you can use the CLI to add, modify, or delete storage disks with deduplication enabled (Dedup Sdisk). Adding a Dedup Sdisk 2 The fsdiskcfg command now includes a -b option to indicate that the storage disk uses blockletized storage to store data.
Managing Storage Disks with Deduplication Enabled Obtaining Dedup Sdisk Information 2 You can obtain information for a dedup sdisk by running the fsmedinfo command on the dedup sdisk.
Obtaining Distributed LAN Client Information Obtaining Distributed LAN Client Information If your StorNext configuration includes distributed LAN clients, you can obtain information through three commands supported by the cvadmin command: • proxy • proxy long • proxy who The proxy Command 2 Use the proxy command to display information about the distributed LAN servers for the file system. In particular, the IP address and port number on which the distributed LAN server is listening is shown.
Using the Dynamic Resource Allocation Feature The proxy who Command 2 Use the proxy who command to display the active disk distributed LAN connections for the specified host, which can be either a disk distributed LAN server or client. Output also includes average I/O statistics for each connection. The syntax for this command is proxy who hostname.
Using the Dynamic Resource Allocation Feature Caution: Checking the File System 2 Before you use a Dynamic Resource Allocation feature, Quantum strongly recommends running the cvfsck command on the file system you will be using. This step could take a considerable amount of time to complete, but your file system should be in good condition before you attempt to expand it or move stripe groups.
Using the Dynamic Resource Allocation Feature 6 Run the cvupdatefs command. 7 Restart the FSM. Adding and Moving a Data Stripe Group 2 New functionality has been added to the snfsdefrag utility to support operations on multiple stripe groups. Note: During Stripe Group Movement, affinities are preserved when files are moved from one stripe group to another.
Using the Dynamic Resource Allocation Feature 8 Run snfsdefrag -G -m 0 -r /filesystemroot where is the zero-based number of the source stripe group from which the move starts, and filesystemroot is the file name of the file system tree’s root. You can specify multiple -G options to use multiple source stripe groups. 9 Verify that no data remains on the original stripe groups. 10 Edit the file system configuration to mark the old stripe groups as “Down.” 11 Stop the FSM. 12 Restart the FSM.
Using the Dynamic Resource Allocation Feature Caution: The metadata/journal stripe group you want to move cannot contain data. Sndiskmove treats metadata and journal stripe groups the same way, so it doesn’t matter whether the stripe group you want to move is a metadata stripe group, a journal stripe group, or a combined metadata and journal stripe group. The only caveat is that stripe groups used for movement cannot contain data.
Using the Dynamic Resource Allocation Feature For example: source-LUN-label-name (the original stripe group name) becomes source-LUN-label-name.old destination-LUN-label-name (the new stripe group name) becomes source-LUN-label-name (the same name as the original stripe group) Note: When you run sndiskmove, it could take a considerable amount of time to copy the data between disks, depending on disk size and performance.
