rgmanager bug fix update

Bug Fix Advisory

Topic

Updated rgmanager packages that fix two bugs are now available for Red Hat
Enterprise Linux 6.

Description

The rgmanager package contains the Red Hat Resource Group Manager, which is used
to create and manage high-availability server applications in the event of
system downtime.

This update fixes the following bugs:

• Previously, if the main rgmanager process died, either by an unexpected
  termination with a segmentation fault or by killing it manually, any service
  running on it, was immediately recovered on another node rather than waiting for
  fencing, like the rgmanager process did in previous versions. This was
  problematic for services containing Highly Available Logical Volume Manager
  (HA-LVM) resources using tagging, because the start operation failed if the tag
  that was found belonged to a node that was still a member of the cluster. With
  this update, service recovery is delayed until after the node is removed from
  the configuration and fenced, which allows the LVM resource to recover properly.
  (BZ#862075)
  
• Previously, attempts to start an MRG Messaging (MRG-M) broker caused rgmanager
  to terminate unexpectedly with a segmentation fault. This was caused by subtle
  memory corruption introduced by calling the pthread_mutex_unlock() function on a
  mutual exclusion that was not locked. This update addresses scenarios where
  memory could be corrupted when calling pthread_mutex_unlock(), and rgmanager no
  longer terminates unexpectedly in the described situation. (BZ#983296)
  

Users of rgmanager are advised to upgrade to these updated packages, which fix
these bugs.

Solution

Before applying this update, make sure all previously released errata relevant
to your system have been applied.
