Chapter 1 1 Introduction StorNext is data management software that enables customers to complete projects faster and confidently store more data at a lower cost. Used in the world's most demanding environments, StorNext is the standard for high performance shared workflow operations and multitier archives. StorNext consists of two components: StorNext File System (SNFS), a high performance data sharing software, and StorNext Storage Manager (SNSM), the intelligent, policy-based data mover.
Chapter 1 Introduction reconfigure applications to retrieve data from disparate locations. Instead, applications continue to access files normally and SNSM automatically handles data access – regardless of where the file resides. As data movement occurs, SNSM also performs a variety of data protection services to guarantee that data is safeguarded both on site and off site. About Distributed LAN Clients 1 StorNext supports distributed LAN clients.

Performing Stripe Group Movement The time it takes to complete the Stripe Group Movement process depends on the amount of data being moved between source and target stripe groups.
Chapter 6 Managing the File System Performing Stripe Group Movement Although the Movement Wizard focuses primarily on data movement, you can also move metadata stripe groups. You can move a metadata stripe group to a new stripe group of the same or greater capacity as the original metadata stripe group. However, during metadata stripe group movement the file system must be down, and no new read/write operations can occur until all metadata has been transferred and the file system is restarted.
Chapter 6 Managing the File System Performing Stripe Group Movement • Type: Specifies whether the move is for a data stripe group or a metadata/journal stripe group • Lun/Stripe Group: The name of the lun/stripe group involved in the move • Start Time: The date and time the move was launched • Percentage Complete: The current percentage complete status for the move • Status: For current moves the status will be Progress. For previously completed moves the status will be either Success or Fail.

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.

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.

Glossary A Affinity : An association between a relation point in the file system and a stripe group. It allows the user to direct data to specific primary disks by writing to the affinities associated relation point. C The operation of logically removing old file versions from a piece of media. This is a database operation that removes knowledge of managed files that have been updated or removed. A piece of media that contains nothing but removed files will not be considered blank until it is cleaned.
Graphical User Interface. G GUI M Managed Directory A directory that has a policy class relationship. Managed File System A file system that enables automatic data movement managed by StorNext Storage Manager between the primary disk and secondary storage (either disk or tape). MediaClass A grouping of media used for storing or retrieving data. Media Storage Manager (MSM) The Media Storage Manager is responsible for controlling media and archives.
Retrieve The process of retrieving data for a file from secondary storage (either disk or tape). S RHAS Red Hat Advanced Server RHEL Red Hat Enterprise Linux SCSI Small Computer System Interface. The interface that is used to talk to most hardware devices such as tape and libraries. StorNext A scalable, high performance, data management solution that ensures the long-term safety and recoverability of data in SAN environments, while optimizing the use of storage resources.
U Undelete The process of returning a file from the Trash can to its original location on disk. This can be done only if the Trash can is enabled. Unmanaged File System A file system that does not have archive capability controlled by SNSM.
Appendix A Operating Guidelines A This appendix contains information pertinent to operating StorNext, as well as some operating guidelines and limitations you should consider. The Reserved Space Parameter As of StorNext 3.0, the method of accounting for reserved space has changed. The MaxMBPerClientReserve parameter from the StorNext file system configuration file (/usr/cvfs/config/*.cfg) has been deprecated. All values except 0 are ignored for this parameter.
The Reserved Space Parameter • Yes - (Default) The MDC reserves enough disk space so that delayed allocations can be converted to real allocations (even when the MDC is restarted and the client is not). The MDC reserves a minimum of about 4GB for each stripe group and up to 280MBs per actively writing client for each stripe group. Note: The amount of reserved space is usually less than 280MB per client. Reserved space is calculated as 110% of the buffer cache size of each particular client.
Distributed LAN Server/Client Network and Memory Tuning Distributed LAN Server/Client Network and Memory Tuning Using the Distributed LAN Server and Client feature places significant additional demands on network capacity and system memory.
Distributed LAN Server/Client Network and Memory Tuning This may reduce the amount of packet loss. However, some Ethernet switches are unable to accommodate true GigE bandwidth, especially when multiple ports are transmitting data at the same time. • Linux Network Drivers. For best performance and compatibility, update Intel e1000 drivers to the latest version. In some cases, enabling TCP offload can cause issues. (Identify these issues by examining netstat -s output for bad segments.
Distributed LAN Server/Client Network and Memory Tuning * transfer buffer count * transfer buffer size) For example, suppose a Windows Distributed LAN Server is serving four file systems to 64 clients each using two NICs for data traffic. Also assume the server uses the defaults of sixteen transfer buffers and 256K per buffer. (On Windows, you can view and adjust the transfer buffer settings using the Client Configuration tool’s Distributed LAN tab.
Configuring LDAP * transfer buffer size) For example, consider a Linux Distributed LAN Server that has two NICs used for Distributed LAN traffic, serves four file systems, and uses the default eight server buffers and 256K per buffer. (See the dpserver and sndpscfg man pages for information about viewing and modifying Distributed LAN buffer settings on Linux.) For this case: Required memory = 1GB + (4 * 2 * 8 * 256K) = 1040MB Note: This example results in a memory requirement of less than 2GB.
Configuring LDAP UNIX File and Directory Modes 1 Note: Compatible Active Directory servers include Windows 2003 Server SP1 (with the Windows Services for Unix 3.5 extended LDAP schema applied,) and Windows 2003 Server R2. Note: Compatible Active Directory servers include Windows 2003 Server SP1 (with the Windows Services for Unix 3.5 extended LDAP schema applied,) and Windows 2003 Server R2.
Setting Up Restrictive ACLs Navigating to the Authentication tab of the Client Configuration Windows utility gives the administrator the ability to disable the NIS/PCNFSD mapping on a client-by-client basis by selecting Use Active Directory. The domain server must be at least Windows 2003 or above to support RFC 2307 mapping.
Event Handles for fsm.exe on a Windows Metadata Server Event Handles for fsm.exe on a Windows Metadata Server The metadata server (FSM) has many data structures that are used internally. Each of the data structures has some locks (pthread_mutex_lock). Each lock is initialized as “uninitialized.” The first time the lock is used, a small amount of memory and an event (i.e., handle) are allocated. The memory and event/handle are retained by the system until the data structure is destroyed.
FSBlockSize, Metadata Disk Size, and JournalSize Settings Values less than 16K are not recommended in most scenarios because startup and failover time may be adversely impacted. Setting FsBlockSize (FSB) to higher values is important for multi terabyte file systems for optimal startup and failover time. Note: This is particularly true for slow CPU clock speed metadata servers such as Sparc.
Allowance for Special Characters The best rule of thumb is to use a 16K FsBlockSize unless other requirements such as directory ratio dictate otherwise. This setting is not adjustable after initial file system creation, so it is very important to give it careful consideration during initial configuration. Example: FsBlockSize 16K 1 JournalSize Setting The optimal settings for JournalSize are in the range between 16M and 64M, depending on the FsBlockSize.
Disk Naming Requirements Beginning with StorNext 3.1.2, the GUI has been modified to handle all known issues with file names containing these non-standard characters. Still, Quantum strongly recommends against deliberately using these characters in filenames. If the GUI encounters a filename containing a “less-than-32” ASCII character, the character is rendered in the display as in the following examples: • A horizontal tab is shown as “__0x09__”. • A line feed is shown as “__0x0A__”.
General Operating Guidelines and Limitations Table 1 Operating Guidelines and Limitations Operating System / Affected Component Description HA configurations In HA (high availability) configurations, do not run adic_control start on the standby server. Doing so may start StorNext Storage Manager components on the standby server which are already running on the primary server, and may result in database corruption. IRIX As of release 3.
General Operating Guidelines and Limitations Operating System / Affected Component Linux Description StorNext does not support the use of loopback IP addresses other than 127.0.0.1. SUSE Enterprise Linux 10 systems sometimes have an entry for 127.0.0.2 in the /etc/hosts file. This causes various FSM operations to fail with the error “Not Local.
General Operating Guidelines and Limitations Operating System / Affected Component Description All UNIX and Linux In a file system configuration file, if the Metadata parameter for a stripe group was set to Yes when the file system was created, do not later change the parameter to No. Doing so will cause the metadata to become inaccessible and result in errors.
General Operating Guidelines and Limitations Operating System / Affected Component Windows Description On Windows systems, StorNext may log error messages after reboot if it tries to start before some other services. For example, if the network is not yet available, a StorNext client cannot contact a StorNext server and posts an error in the logs. (The client will continue to retry the connection until it is successful.
General Operating Guidelines and Limitations Operating System / Affected Component Windows Description When you are upgrading to StorNext 3.5 from a release prior to version 3.0, you must uninstall StorNext before installing. After uninstalling you must reboot, install StorNext 3.5, and then reboot again. In future releases, upgrading from StorNext 3.5 should not require a reboot after installing.
General Operating Guidelines and Limitations Operating System / Affected Component Description Windows For Windows Server 2008 and Windows Vista: 1 On the Windows client machine, right-click the Recycle Bin icon on the desktop and then click Properties. 2 Click the General tab. 3 Select the mapped drive that corresponds to the StorNext mapped file system. For directory-mounted file systems, select the file system from the list. 4 Choose the option Do not move files to the Recycle Bin.
General Operating Guidelines and Limitations Operating System / Affected Component All Description Be aware of the following limitations regarding file systems and stripe groups: • The maximum number of disks per file system is 512 • The maximum number of disks per data stripe group is 128 • The maximum number of stripe groups per file system is 256 • The maximum number of tape drives is 256 To prevent data loss and aid disaster recovery, Quantum recommends adjusting policy settings to retain two copies o
General Operating Guidelines and Limitations Operating System / Affected Component All Description The Move Stripe Group Data feature (part of Dynamic Resource Allocation) does not support moving sparse files. Sparse files are files that lack on-disk allocations for some of the data within the data range indicated by the size of the file. A stripe group is defragmented as part of the data moving process.
General Operating Guidelines and Limitations Operating System / Affected Component All Description In StorNext 3.0, the default buffer cache settings have been modified. Previously, all reads/writes that were 64K or smaller went through the buffer cache while larger I/O requests went direct. In StorNext 3.0, read/writes that are 1MB or smaller go through the buffer cache, while larger I/O requests go direct. The new buffer cache settings may change the I/O behavior of some applications.
General Operating Guidelines and Limitations Operating System / Affected Component All Description As of SNFS 2.7, a change was made to the way that the Reserved Extents performance feature affects free space reporting. In the previous release, SNFS would reserve a certain amount of disk space which would cause applications to receive an out of space error before the disk capacity reached 100%. In the current release, this reserved space is treated as allocated space.
General Operating Guidelines and Limitations Operating System / Affected Component All Description As a result of log rolling changes in StorNext 3.0, logs are now rolled every 6 hours. For each log, 28 instances (7 days of logs) are retained. Log instances are retained in the same directory as the original log. All log files which are rolled are affected by this change, including TSM logs (tac_00, bp_*.log, hist_01, etc.), MSM logs (tac_00, hist_01, etc.), and any other components configured for rolling.
Appendix B HA Failover B 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 C Using The Command Line Interface C 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 3 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 3 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 3 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 3 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 3 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 3 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.
Specifying an Alternate Retrieval Location 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.
