Readme and Release notes for release 4.2.3.3 IBM Spectrum Scale 4.2.3.3 Spectrum_Scale_Advanced-4.2.3.3-ppc64LE-Linux Readme

Unless specifically noted otherwise, this history of problems fixed for IBM Spectrum Scale 4.2.x applies for all supported platforms.

Problems fixed in IBM Spectrum Scale 4.2.3.3 [July 27, 2017]

• Fix an issue in AFM environment where lookup and metatdata operations on same file from different nodes causes the daemon assert.
• Allow a user to specify the afmrpo interval in weeks[W],days[D] or hours[H].
• Fix a fcntl revoke handler exception that can occur after an EIO error.
• Fix a pdisk firmware version attribute issue. After the pdisk firmware level is changed, mmlspdisk still shows the old version which may mislead the administrator.
• Change EIO to ESTALET for open operation of a file that was deleted.
• Fix a race condition that causes command to fail with "invalid version on put".
• Don't allow kernel modules to cleanup when removing gpfs.gpl if gpfs.gplbin is currently installed.
• Fix an Assert: exp(dm != inv) L-813 in ../fs/fsop.C which can occur when trying to resend a read event.
• Fix a mmfsd crashes, due to a Signal 6 (abort). This can happen removing socket connections in a CCR environment.
• Fix a very rare fault that can occur during heavy directory update workloads.
• Fix a problem in which mmchfirmware --type storage-enclosure fails if running in adminMode=central where only one node has ssh privileges. This fix applies to GSS/ESS customers.
• The mmlsmount command has been changed on all platforms. The change only affects the output format of the -Y argument only when IPv6 address is used.
• This change does not allow mmchcluster -p LATEST on a CCR enabled cluster.
• This fix a problem in which unnecessary allocation manager cursors are being consumed.
• Fix an assert "ioStatsP == __null" that can occur when creating a file system with "-v yes" option, after the "fastest" readReplicaPolicy is enabled.
• Fix a err 112 rename failure that can occur during recovery for IW fileset.
• Fix an AIX kernel crash due to assert "freeing vnode not on gnode list".
• Fix an issue in the AFM environment where an unresponsive target causes a queue to be dropped during the attribute setting.
• Fix a problem where a verbsRdmaSend enable node sent excessive nsdMsgRdmaPrepare to an AIX node.
• Fix a replicas mismatch problem caused by mmrestripefs -b wrongly resetting the missupdate flag.
• Fix CCR and/or mmsdrcli-RPC request errors that can occur during authentication of the incoming socket connections.
• Address a problem where renames across directories do not reset the dirty bit which in future leads to a big list of dirty directories and hence recovery on AFM filesets might take longer to scan.
• Fix an issue in the AFM environment where UIDs in ACLS are not remapped during replication over NSD protocol when UID remapping is enabled.
• When an AFM fileset is to be converted to a regular independent fileset, first check for incomplete dirs, uncached files and orphans. If found inform the user to run prefetch, prior to the conversion.
• Fix a condition where mmautoload may hung.
• Fix a mmlogsort failure that can occur when mmlogsort attempts to query the time zone information on a node that is down.
• Fix a gpfs.snap command failure in a sudo wrapper environment if the legacy log timestamp format is used.
• Fix a divide by zero problem, when running mmrestripefs, which is specific to a file system using directly attached disks only with no NSD servers defined.
• Fix a dynassert 'mmapFlushSXLock.isLockedShared' which may fail as a secondary failure while daemon is shutting down.
• Fix a problem in which a CES ip could not be removed from a node. This can occur when problems are occurring during a CES ip move or failover (e.g. network issues, CCR issues, quorum loss). Subsequent runs of mmcesnetworkmonitor did not fix this and the ip remain active on a node where it should not.
• This fix adds more group memberships (up to 2048) on AIX.
• Fix a "freeSpace != __null" assert. This issue could only happen when doing file system rebalance after suspending some disks.
• Fix a problem in which you get a Unable to create file in fileset error even if the inode limit is not reached which is most likely to occur if the user fills up the fileset from a single node.
• Fix mmcommon test scpwrap.
• This update addresses the following APARs: IV97601 IV97676 IV97677 IV97678 IV97680 IV97681 IV97682 IV97683 IV97685 IV97693 IV97808 IV97836 IV98052 IV98053 IV98054 IV98058.

• Fix a ccrio initialization failure (err 811) when changing the daemon-interface.
• Fix a rare segmentation fault in the mmgetstatus command.
• Fix a SIGBUS error that can occur during a mmap read on a snapshot file.
• Fix a problem in which we see a flood of "failed to scrub vdisk" log message when GNR node experiences quorum loss. This is for ESS/GSS.
• Fix a rare race between unlink, lookup and token revoke which causes kernel crash in d_revalidate.
• This fix will make sure Ganesha request reference a valid GPFS filesystem.
• Fix a system hang that can occur when a file system is suspended while doing a mmap.
• This fix rejects unreasonable large requests to preallocate inodes immediately with ENOSPC.
• Fix a directory rename issue with IW filesets that can occur if the rename target is an existing directory.
• Fix a fault that can occur when restripe runs while the SG is not mounted on all NSD nodes.
• This fix restricts the afmMaxParallelRecoveries config value from 0 to 128.
• This fix removes the unnecessary error message "cannot open /proc/net/tcp6" when shutting down GPFS.
• Fix a problem with not properly handling quotas in an AFM environment. This can occur when you have very large hard and soft limit values.
• Fix a "exp(!sgP->isSGMgr())" assert that can occur when you delete a file system and then create a new file system with the same name at the same time.
• Fix an err 112 that can show up in the mmfs logs when mmchnode --gateway is executed.
• Fix a kernel crash that can occur while attempting to mount a loop device to a correspond file in a GPFS file system or while using a GPFS file system file as a LIO backend.
• Address a problem where applyUpdates continues to run even if the fileset at the old primary is unlinked or the mmfs daemon has been shutdown.
• Fix an outband resync failure that can occur if a recovery is triggered by deleting some files in a directory and the directory itself. This is an AFM/DR environment.
• Fix rename conflicts that can occur in SW/DR filesets.
• Update log code to prevent log recovery error when log file became illReplicated. This could happen on file system with -K set to NO and there is not enough disk space for full replication.
• This fix will use new interface that will reduce multiple retries every time a lock is freed and there are multiple waiters for the lock.
• Fix an assert that can occur with a DR fileset and the file system is suspended.
• Fix bug that requires a large free space in /var/mmfs to run change commands.
• Fix recovery failure err 17 when psnap0 deletion fails.
• Fix a daemon assert that can occur in an AFM environment where the mmfsd daemon fails to start repeatedly with a DMAPI enabled filesystem at a gateway node.
• Address a problem where trying to queue a writeSplit message to the helper gateway's queue can fail with an error 28 (E_NOSPAC).
• Fix an issue which returns EACCESS(errno = 13) while running mmapplypolicy when there is a mounted NFS file system which has the same name with a GPFS file system.
• A fastpath optimization defect can result in an internal error to be returned to the user when it is safe to continue without entering the fast path.
• Install if you suffer from mmapplypolicy/tspolicy hanging after otherwise finishing all work.
• cNFS: fix a problem with /usr/sbin/rpcinfo not found in SLES12 or later.
• Fix a failure in Object Authentication configuration with Active Directory or LDAP. This fix is only required if Object is being configured with Active Directory or LDAP and DN of Swift service user(specified in --ks-swift-user) is more than 79 characters.
• Fix a problem with ESS disk replacement in which the mmchcarrier command may wipe out the pdisk location code. The problem will prevent the subsequent mmchcarrier command to proceed without a valid location code.
• Fix a problem in which a GPFS command may wrongly terminate another process.
• Fix a rare deadlock problem caused by stream write(enableRepWriteStream=yes).
• Update log recovery code to avoid GPFS daemon assert after detecting invalid directory block during log recovery. Code has been changed to log a FSSTRUCT error and fail the log recovery so offline mmfsck can be run on the file system.
• Fix a mmfsd crashes (incompleteOk assertion), when the number of files in the committed directory doesn't match the number of files in CCR's file list in case of a new CCR file update request.
• This update addresses the following APARs: IV94991 IV94992 IV94994 IV94995 IV94996 IV94997 IV94998 IV95015 IV95021 IV95230 IV95557 IV95643 IV95925 IV96037 IV96163.
