Problems fixed in GPFS 3.3.0.2

November 12, 2009

Note: This service level addresses the below issues. This is not a definitive list as other minor corrections have been made which are not listed here.

• On Windows, mmtracectl no longer requires ActiveState Python in order to collect and format traces.
• During a stripe group mount, ignore the 'exclDisks' mount option for a filesystem in a remote cluster.
• Fix direct I/O path to set the Windows archive bit only for writes, not reads.
• Add more trace information and ifdef for problems with Linux NFS fast lookup.
• Ensure mmexportfs does not remove tiebreaker disks unless device name is "all".
• Fix kernel exception in fifo_open due to an invalid i_pipe pointer.
• Increase prefetchThreads+worker1Threads+nsdMaxWorkerThreads to 1500 on AIX 64bit systems.
• Added two new calls to the inode scan api to allow dmapi attributes to be backed up and restored for disaster recovery. The dmapi attributes are also saved in a snapshot of the original file on which they were set.
• Collect the output of systeminfo.exe command instead of the command itself.
• Fix trace record missing problem. The _STrace function should pass non-blocking flag as 0 instead of 1 to rl_trc_write.
• Improve SMP scalability in the DIO code path.
• Fix small window where message send will hang if destination list includes the local node and all other nodes reply before the local send can start.
• Prevent force unmounts when disks in different failure groups (FGs) fail, but are in different pools. Prevent marking disks down in multiple FGs when disks die simultaneously.
• Allow command line case insensitive hostname.
• Add an new file system option --filesetdf.
• Fixed assert when deleting files from a dmapi enabled filesystem.
• Dmapi locks are ignored from lock file operation during offline fsck as offline fsck doesnt have any dmapi context. This will prevent offline fsck from crashing the deaom while fixing orphans in a dmapi enabled filesystem.
• Fix mmapplypolicy to accept a policy that includes a 3-value THRESHOLD(hi,lo,pre) clause in a migrate to external pool rule.
• Ensure mmfsctl syncFSconfig does not affect free disks unless device name is "all".
• Ensure mmaddnode fails if the IP address already appears in the cluster.
• Fix node crash from destroy event when accessing stalled stripe group.
• Correct mmcrnsd disk sector size (>2T) error on 32bit Linux.
• Fix mmpolicyExec-hsm.sample to handle characters \ " and ' in filenames properly so that they work in HSM file list.
• Fix deadlock during FS manager takeover if previous FS manager and its disks (site failure) fail at the same time.
• Fix DMAPI enabled filesystems when they are mounted on top of another GPFS filesystem.
• Fixed performance problem while migrating files.
• To avoid 32-bit integer overflow in case of huge sparse file, argument dataBlockNum in repairDataBlock is changed to Int64 instead of int.
• Modified GPFS installation on Windows to prevent GPFS from being started after a package update, but before the mmwinserv service is configured. This problem can result in permission errors when running GPFS administrative operations.
• Fixed a problem in GPL layer makefile so that no warning messages will appear when upgrading from 3.3 GA code on Linux platform when GPL layer has never been compiled before.
• Acquire the stripe group descriptor mutex before changing the quota files inode information in the stripe group descriptor.
• On Windows, error messages related to the mmwinserv service were improved to provide clearer indication of the problem and how it might be corrected.
• Fixed the allocation code which caused an infinite loop when running out of full metadata block.
• Fix for a rare race condition that may result in a "Busy inodes after unmount" syslog message on Linux.
• Fsck generates false positives for bad repication status in user metadata files after a failed PIT operation. The fix ensures that fsck does not generate the false positives.
• When fixing orphans, fsck now prints the fileset name from which the orphan is generated.
• Fix mmbackupconfig to present a clearer error message when they attempt to run the command when the filesystem is mounted.
• Fix mmapplypolicy command to indicate it is making progress.
• Hold the stripe group descriptor mutex only while actually accessing/updating the stripe group descriptor when updating the quota file information in the descriptor.
• Avoid crash in rare cases of concurrent multi-node file creates.
• Prevent customer files that have been backed up to the TSM server from expiring in the same session.
• Enabled global cluster wide events from remote cluster in user exit callbacks.
• Fix "mmtrace noformat" to work on linux nodes.
• Correctly propagate authorization key files to new node in admin central cluster.
• Fixed repair code which can caused snapshot file corruption which could happen when filesystem contains fileset, snapshots and deleting disk resulted in not enough failure group for proper replication of metadata.
• Clarify mmwinserv error messages.
• Fix rare deadlock that occurs during recovery of large filesystem.
• Fixed GPFS trace control on Windows which in some scenarios was not restarting trace collection correctly.
• Fix backward compatibility problem that caused file creates to fail on file systems that were originally created with GPFS version 2.2 or earlier.
• This update addresses the following APARs: IZ63058 IZ63080 IZ63171 IZ63307 IZ63308 IZ63320.
