6.0.2 HP IBRIX X9000 Storage Release Notes (AW549-96044, January 2013)

• 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.
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
• 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 17) for more information.
• When a CIFS share included a $ character in the path, CIFS clients could not map the share.
• When a cluster with more than two nodes was upgraded, the Statistics tool upgrade failed.
• The Statistics tool could fill the root partition with data for historical reports. Historical data and
reports are now written to /local/statstool/histstats by default. See “Updates to the
Statistics tool documentation” (page 17) for changes to Statistics tool procedures.
• The CIFS service dumped core during Data Protector backups/restores or drag and drop
operations.
• The default UID for the CIFS Guest account could not be changed if it conflicted with another user.
You can now delete the account and recreate it with a new UID. Use the following command to
delete the Guest account, and enter yes when you are prompted to confirm the operation:
/opt/likewise/bin/lw-del-user Guest
Recreate the Guest account, specifying a new UID:
/opt/likewise/bin/lw-add-user –-force --uid <UID_number> Guest
To have the system generate the UID, omit the --uid <UID_number> option.
• Attempts to join a domain failed if the /etc/hosts file had a duplicate or uppercase alias.
• When ibrix_snap was used to enable a snaptree, the command reported that the directory
was already a snaptree; however, other commands could not locate the snaptree.
