HP Tru64 UNIX and TruCluster Server Version 5.1B-6 Patch Summary and Release Notes

6. The write from step 5 returns to the application.
7. The system crashes.
• Corrects the NFS server's handling of files open for direct I/O.
• Fixes an internal problem in the kernel's AdvFS, UFS, and NFS file systems where extended
attributes with extremely long names (greater than 247 characters) could not be set on files.
The new limit is 254 + a null string terminator.
• Corrects a problem that can produce the following symptoms:
— When producing a clone of a file (that is, a fileset has been cloned and one of its files is
being written to) or when migrating a file (defragment, migrate, balance, rmvol),
directories lose attributes and are seen as files, and files lose their ACLs and other
attributes under the following circumstances:
◦ On multi-volume domains with a volume that is out of space
◦ By the use of a property list on a multi-volume domain
— The rmvol command enters into an infinite loop while trying to move a file from one
volume to another.
• Fixes a problem where threads can hang when performing a malloc() function.
• Prevents a kernel memory fault panic in _OtsMove when going through the fs_read() routine.
• Prevents a potential hang during a umount if a domain_panic has been encountered.
• Provides a workaround for a domain panic when a data inconsistency in the deferred-delete
list of an AdvFS file system is detected.
• Corrects idle-wait time accounting within the AdvFS file system, as reported by vmstat -w.
• Corrects a condition in which command response deteriorates to about 30 seconds when
doing an rmvol on a domain with a volume containing large files (8 GB).
• Removes the obsolete function bs_bfdmn_flush_all.
• Prevents a potential unaligned memory crash when ACLs are on.
• Eliminates the lock_terminate: lock owned panic.
• Fixes a problem where data from an AdvFS file with a frag could be written to an incorrect
location if an NFS client grew the file.
• Fixes an AdvFS asynchronous direct I/O problem that can cause a thread to hang.
• Fixes a problem encountered where a truncated AdvFS file erroneously zeros data for the
remaining leading segment of the file.
• Corrects a condition that causes a panic resulting from a kernel memory fault in
access_invalidate.
• Corrects a problem in mount or domain activation after a panic, where a fileset (domain)
cannot be mounted without running fixfdmn.
• Improves performance for CFS filesets mounted with the server_only option. A log sync for
create transactions is not needed for such filesets.
• Fixes a cluster panic with the following error message:
panic (cpu 3): ics_unable_to_make_progress: heartbeat checking blocked
• Fixes an rmvol E_PAGE_NOT_MAPPED error.
• Eliminates an ENO_MORE_BLKS error seen performing a copy-on-write procedure to a
clone file while an rmvol operation is in progress.
• Increases from 4 to 6 the number of pages that can be pinned at deletion time.
• Improves the informational messages returned by a few domain panic strings.
• Fixes an error in some sections of code that get E_PAGE_NOT_MAPPED errors when the
code expected the page to exist.
• Closes a small race accessing internal data structure in AdvFS.
• Prevent a potential panic when AdvFS looks up a file name.
• Corrects the following problems in AdvFS write logic:
