6.1.4 HP IBRIX X9000 Storage Release Notes

restrictions have been implemented on rename operations. The following restrictions apply to hybrid
file systems:
• Only directories created in version 6.0 or later can become snap tree roots.
• If the old directory is not in a snap tree and the new directory is in a snap tree, rename is allowed
only if the object being renamed is snapable (that is, it has the new inode format).
The following restrictions apply to both hybrid file systems and pure 6.x file systems:
• A snap tree root cannot be renamed. Also, the path to a snap tree root cannot be changed.
• Rename is allowed when neither the old directory or the new directory are in snap trees.
• Rename is allowed when the old directory and the new directory are in the same snap tree.
Rename is not allowed when the directories are in different snap trees.
These restrictions are intended to prevent hybrid snap trees containing files with the old format. However,
hybrid snap trees can still occur when a directory having the new format is populated, using rename,
with old format objects and that directory is then made into a snap tree root or is renamed into a snap
tree. The X9000 software does not prevent this situation because it could take a prohibitively long
amount of time to perform a complete scan for old objects in the sub tree being moved if the new sub
tree was sufficiently large.
Fixes
This section provides information about the fixes in a release.
Fixes in the 6.1.4 release
• Directory change notification was not working for SMB1 clients.
• Administrators were unable to add a user as “nasxxx” in CIFS Authentication.
• Share administrators were unable to add users and groups with parenthesis and ampersands in
the name to a CIFS share.
• The Windows IBRIX Client (WIC) would crash when WIC was built in debug mode.
• A memory leak was occurring in Fusion Manager.
• There were SAS topology issues, resulting from firmware flashes and simultaneous blade boots.
• The var/log/message file was not getting rotated nightly.
• Thousands of /tmp/tmp*.lvmtool directories were being created.
• IBRIX nodes were not discoverable when the Fusion Manager IP was used in HP Systems Insight
Manager (SIM).
• A crash would sometimes occur while renaming a folder.
• Quotas were being incorrectly reported after an upgrade.
• The IoLockFile FSD interface was crashing frequently (4 to 9 minutes intervals) because of an
assertion failure in file locking.
• The ibrix_fsck command was showing "illegal inode number while reading inode."
• The message LW_ERROR_INVALID_PARAMETER was appearing frequently in the logging.
Fixes in the 6.1.3 release
• The quota current size would be reduced after running the rebalance task, even though files were
not modified or deleted. During movement of files across segments, there are intermediate replica
files that are created. Once data from an original file is synced with its replica, the original file
is deleted and replica is promoted as the original file. These replicas have to be marked with the
directory quota ID same as that of the original master file, but that was not occurring. As the
