Bug Fix Advisory

Topic

Updated rgmanager packages that fix several bugs are now available for Red Hat
Enterprise Linux 5.

Description

The rgmanager packages contain the Red Hat Resource Group Manager, which
provides the ability to create and manage high-availability server applications
in the event of system downtime.

This update fixes the following bugs:

• A mirror device failure during the relocation of the High Availability LVM
  service (HA-LVM) could cause, under certain circumstances, the service to fail.
  This bug has been fixed and now the mirror device failure no longer affects the
  HA-LVM service in such a case. (BZ#693855)
  
• The orainstance.sh resource agent did not detect all startup failures
  properly. The underlying source code has been modified and all failures are now
  detected correctly. (BZ#723819)
  
• LVM resource agent could not update logical volume tags if there were missing
  physical volumes. This bug has been fixed and the logical volume tags are
  forcibly removed if the physical volumes are missing. (BZ#756180)
  
• If the cman service was stopped while the rgmanager service was running,
  rgmanager sometimes exited uncleanly without releasing its Distributed Lock
  Manager (DLM) lock space. Consequently, it was impossible to shut down rgmanager
  and cman. Now if the user mistakenly attempts to stop cman service while
  rgmanager is still running, rgmanager no longer stops in this situation.
  (BZ#769730)
  
• If the /etc/lvm/lvm.conf file was changed after the last initrd (initial
  ramdisk) rebuild, the LVM resource agent failed. This agent has been modified to
  generate a warning message and no longer fails in such a case. (BZ#773372)
  
• If a service with a relocate failover policy failed and the relocation
  operation failed as well, the service could be restarted locally. Due to an
  error in the source code, the service afterwards stopped, even if the local
  restart succeeded. This error has been fixed, and these services no longer stop
  after a successful local restart. (BZ#789366)
  
• When the root file system was full, rgmanager randomly killed applications
  when trying to force-unmount. The underlying source code has been modified and
  applications are stopped instead of killed in this case. (BZ#819595)
  
• Under rare conditions, rgmanager attempted to free memory that had been
  previously freed. As a consequence, rgmanager terminated unexpectedly with a
  segmentation fault. This bug has been fixed and rgmanager no longer attempts to
  free previously-freed memory. (BZ#820632)
  
• When rgmanager received a remote start message for a particular service while
  already in the process of starting that service locally, a deadlock could occur.
  This sometimes happened during recovery of a service that had failed its start
  operation. This bug has been fixed and rgmanager works as expected. (BZ#834459)
  
• If the contents of the /proc/mounts file changed during a status check
  operation of the file system resource agent, the status check could incorrectly
  detect that a mount was missing and mark a service as failed. This bug has been
  fixed and rgmanager's file system resource agent no longer reports false
  failures in the described scenario. (BZ#847125)
  

This update also adds the following enhancements:

• A new "prefer_interface" parameter has been added to the rgmanager ip.sh
  resource agent. This parameter is used for adding an IP address to a particular
  network interface if a cluster node has multiple active interfaces that have IP
  addresses on the same subnetwork. (BZ#819494)
  
• In some cases, "fs unmount" command and clustersfs resource agents were unable
  to unmount the file systems which were exported by the nfsd utility. The new
  nfsrestart option to enable a last resort workaround prior to failing to unmount
  the file system has been added. The new option requires force_unmount="" to be
  enabled and it is not compatible with nfsserver resource agent. (BZ#822066)
  

All users of rgmanager should upgrade to these updated packages, which fix these
bugs and add these enhancements.
