Version: 6.0.2 (build 6.0.384) Description This release contains updates to HP X9000 File Serving Software, HP X9320 and X9720 Network Storage Systems, and HP X9300 Network Storage Gateway systems. The X9000 Software features a highly scalable file system, CIFS, NFS, FTP, and HTTP file services, high availability, remote replication, data validation, snapshots, data tiering, and CLI and GUI management interfaces, and is installed on HP Network Storage System and Network Storage Gateway servers.

panels. The Active Tasks panel shows active tasks for remote replication, segment rebalancing, data tiering, case insensitivity, snapshot space reclamation, and data validation. The Inactive Tasks panel shows tasks that have completed or have been stopped. The new ibrix_task –c option displays information about inactive tasks. About the 6.0 release X9000 6.
Agile management console The agile management console is now required on all file serving nodes. The management console is active on one node and passive on the other nodes. Spillover Spilling over sequentially written files from one segment to another is disabled in the 6.0 release; no new spillover chunks will be created. If a segment is full, writes to files in that segment will fail with -ENOSPC (-28), even if there is space available in other segments. Existing spillover files generated in the 5.
ibrix_crr –s –o –f srcFs –S a/b/c –C tcluster –F destFs –X 1/2/3 –P a/b/c The replication now goes to /destFs/1/2/3/a/b/c{contents_under_c}. NOTE: CRR does not support replicating from any 5.x cluster to a 6.0 cluster, or from a 6.0 cluster to any 5.x cluster. Block snapshots The following changes have been made in this release: • Block snapshots can now be scheduled only through the GUI. The ibrix_at command is no longer supported. • The names of the CLI commands have been changed.
NOTE: If you need to uninstall only the agile management console packages from a node, retaining the file serving software packages, use the ibrixinit -tmo option. For example, if the passive management console is configured incorrectly on a node or has a corrupt fminstance.xml file, run the following command to uninstall the agile management console RPMs and unregister the passive agile management console on the node: ibrix/ibrixinit -tmo -u Fixes Fixes in the 6.0.
• When a snapshot was taken, files could be deleted from the source directory. • CIFS shares were inaccessible, and the Windows client accessing the filesystem using CIFS would be shown the message: The specified server cannot perform the requested operation. The cause was an SMB 2.0 credit exhaustion issue that was seen on applying a specific load pattern for a prolonged period of time on an HP-SMB server.
• A race condition caused a rebalance operation to fail with the message ASSERT[deleg->dlg_side == idel_ds] failed: Trying to send downgrade delegation to local or remote delegation. • When a segment becomes unavailable, that state persists after remounting the filesystem or migrating the unavailable segment. The segment unavailable state must now be explicitly cleared. The following message appears after a segment unavailable alert: Filesystem includes one or more unavailable (or read-only) segments.
Management console • If the management console service is stopped on the active management console and, within a minute, the passive management console experiences a shutdown or reboot, the passive management console will become active when the node is restarted. When the fusionmanager is started on the formerly active management console (or that node is rebooted), that management console will also be in active mode.
• The ibrix_localusers -i command fails if the user information includes commas. To enter commas in the user information, use the management console GUI instead of the CLI. • When you use the Windows security tab to add local users or groups to a security ACL on a CIFS file (for either file or share-level permissions), you typically specify the user to add as either a DOMAIN\username or a MACHINE\username.
Block snapshots • Snapshot creation may fail while mounting the snapshot. The snapshot will be created successfully, but it will not be mounted. Use the following command to mount the snapshot manually: ibrix_mount -f -m / • Quotas are disabled on block level snapshots (for example, MSA2000 snapshots) and the quota information from the origin file system is not carried to the block level snap file system. Block level snapshots are temporary file systems that are not writable.
xattr value ibrix.virtual.retention_state, Operation not supported, or Error recovering attributes. • The ibrix_vs_snap command cannot delete a block snapshot file system that is enabled for data retention. Instead, use the ibrix_fs command with the -R option. For example: ibrix_fs -d -f block_snap_ifs2_1 -R Segment evacuation • The segment evacuator cannot evacuate segments in a READONLY or BROKEN state.
• Email notifications do not include information about failed attempts to collect the cluster configuration. • In some situations, ibrix_collect successfully collects information after a system crash but fails to report a completed collection. The information is available in the /local/ibrixcollect/ archive directory on one of the file serving nodes.
The default value of this command is 900; the value is in seconds. A higher value reduces the probably of all components toggling from Up to Stale and back to Up because of the conditions listed above, but will increase the time before an actual component failure is reported. HP Insight Remote Support • In certain cases, large number of error messages such as the following appear in /var/log/ hp-snmp-agents/cma.
Upgrades • If clients previously mapped a CIFS share using the hostname/FQDN, they will be prompted continuously to enter their credentials when attempting to access the CIFS share after the upgrade. (The share can be accessed successfully using the IP address.) To workaround this situation, disjoin and then rejoin all file serving nodes to the Active Directory domain. This can be done using the GUI or the ibrix_auth command.
/usr/local/ibrix/bin/verify_client_update The following example is for a RHEL 4.8 client with kernel version 2.6.9-89.ELsmp: # /usr/local/ibrix/bin/verify_client_update 2.6.9-89.35.1.ELsmp nl Kernel update 2.6.9-89.35.1.ELsmp is compatible. If the minor kernel update is compatible, install the update with the vendor RPM and reboot the system. The X9000 client software is then automatically updated with the new kernel, and X9000 client services start automatically.
