5.6.3 HP IBRIX X9000 Release Notes (AW549-96043, December 2012)

• During a mkdir operation, the xdr_encode_netobj dereferencing NULL
xdr_netobj->data pointer message was displayed. The underlying issue has been resolved
so the message no longer appears.
• The root file system was constantly running out of space. This release provides the option, -l, for
placing log files in an alternative location for the ibrix_fsck -p 1 and ibrix_fsck -p 2
commands. Use the -l option to prevent the root file system from running out of space. For
example:
ibrix_fsck -p 1 -l /home/user/
ibrix_fsck -p 2 -l /home/user/
In these examples, /home/user/ is the alternative location.
Corrected in 5.6.2
The following fixes were made in this release:
• The chapter “Upgrading the X9000 Software” in the administrator guides was incomplete. See
“Upgrades to 5.6” (page 19) for more information.
• When a local user or group was deleted, the user or group was not deleted from the CIFS
database.
• An lwiod failure caused the CIFS service to stop.
• An attempt to create a file over RPC succeeded, but the file did not exist.
• When a user quota setting was changed, the ibrix_edquota -l command reported the error
RealQuotaMonitor - directory tree quota has unparsable output.
• The Linux X9000 client did not start after a minor kernel update. A new utility is now available
to determine whether a minor kernel update is compatible with the X9000 client software. See
“Installing a minor kernel update on Linux clients” (page 20) for more information.
• Attempts to join a domain failed if the /etc/hosts file had a duplicate or uppercase alias.
• 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.
Recommendation: verify storage health and contact customer support to run FSCK.
To proceed with mounting segment as unavailable (or read-only), use force option.
When a segment is successfully evacuated, the file system segment unavailable alert is displayed
in the GUI and attempts to mount the file system will fail. There are several options at this point:
◦ Mark the evacuated segment as bad (retired), using the following command. The file system
state changes to okay and the file system can now be mounted. However, the operation
marking the segment as bad cannot be reversed.
ibrix_fs -B -f FSNAME {-n RETIRED_SEGNUMLIST | -s RETIRED_LVLIST}
◦ Keep the evacuated segment in the file system. Take one of the following steps to enable
mounting the file system:
– Use the force option (-X) when mounting the file system:
ibrix_mount –f myFilesystem –m /myMountpoint –X
– Clear the “unavailable segment” flag on the file system with the ibrix_fsck command
and then mount the file system normally:
ibrix_fsck -f FSNAME -C -s LVNAME_OF_EVACUATED_SEG
