Bug Fix Advisory

Topic

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

Description

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

This update fixes the following bugs:

• Due to an unlocked access to internal DBus data structures from different
  rgmanager threads, rgmanager could terminate unexpectedly inside dbus library
  functions when running rgmanager without the "-q" flag (set as default). The
  underlying source code has been modified and rgmanager no longer fails in this
  situation. (BZ#825375)
  
• Previously, rgmanager preferred two nodes in a three-nodes cluster, which
  caused the third node being unused. The configuration has been changed and
  rgmanager now uses all nodes in the cluster as expected. (BZ#831658)
  
• Previously, the cpglockd init script was not included in the chkconfig
  configuration file. This updated adds cpglockd in this file. (BZ#833347)
  
• Resource Group Manager fails to stop a resource if it is located on an
  unmounted file system. As a result of this failure, rgmanager treated the
  resource as missing and marked the appropriate service as failed, which
  prevented the cluster from recovering the service. This update allows rgmanager
  to ignore this error if a resource has not been previously started with a
  service. The service can now be properly started on a different host.
  (BZ#853251)
  
• 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 the recovery of a service that had failed its
  start operation. This bug has been fixed and rgmanager works as expected.
  (BZ#861157)
  
• When a service is configured with a recoverable resource, such as nfsclient, a
  failure of that client correctly triggers the recovery function. However, even
  if recovery operation was successful, rgmanager still stopped and recovered the
  service. The underlying source code has been modified and rgmanager no longer
  stops successfully recovered clients. (BZ#879031)
  

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