HP Tru64 UNIX and TruCluster Server Version 5.1B-5 Patch Summary and Release Notes (March 2009)

• Fixes a hang that occurs in file systems between racing memory-mapping threads.
• Turns a potential AdvFS panic into a domain panic.
• Corrects a problem with the AdvFS bitfile state where, under certain circumstances,
the state of the bitfile is changed without holding the lock that protects the state.
• Fixes an issue with vfast in which a vfast thread might cause a "kernel memory
fault" panic because of a race condition.
• Fixes a potential panic on an active domain doing heavy I/O while trying to create
a new fileset.
• Fixes problems that occurs when volume expansion (mount -u -o extend) races
with other code.
• Fixes a rare simple lock timeout during domain deactivation.
• Fixes a potential hang in AdvFS.
• Converts non-severe system panic calls to AdvFS domain panic calls while
renaming files under AdvFS.
• Corrects a problem in which an ENOSPC error is returned on a fragmented AdvFS
file system even though space is available. On a cluster, this can lead to a CFS
WRITE ERROR.
• Fixes a premature out-of-space condition that can occur as a result of repetitively
extending the size of the volume.
• Fixes resource leaks seen after a device file gets revoked.
• Fixes a delete failure due to a “Disc quota exceeded (EDQUOT)” condition.
• Fixes a data inconsistency that could result from the failure of an I/O request at
the CFS Server due to exceeding the fileset quota.
• Improves AdvFS informational messages as follows:
— Advscan now reports if a domain has all of its volumes, but they are stored in
a different directories. This scenario will cause mount to fail.
— The AdvFS I/O error message now includes the location of a file that will help
users to translate the error number into an error message.
• Prevents race conditions that could cause a kernel memory fault while doing a
migrate and a rmvol on a striped file.
• Modifies the CFS flushing behavior during an rmvol.
• Helps reduce the size of extent maps of clone files cases where the original is
modified extensively under direct I/O.
• Enhances /sbin/AdvFS/tag2name command to print the name of the associated
directory when given the tag of an index file.
• Corrects a potential problem with modifying files via direct I/O when there is a
clone fileset.
• Fixes a race during AdvFS volume removal that can cause a panic in the
bs_osf_complete() routine.
• Fixes a problem when monitoring I/O via AdvFSstat.
