RHBA-2011:0750 - Bug Fix Advisory

Topic

An updated rgmanager package that provides bug fixes and adds enhancements is
now available.

Description

The rgmanager package contains 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 addresses the following bugs:

• clustat now correctly displays flags when a service is frozen or partially

failed. (BZ#634298)

• clufindhostname -i no longer returns a random value. (BZ#661881)
• Restricted failover domain boundaries are now honored when performing virtual

machine migrations. (BZ#621694)

• clustat no longer returns 255 if rgmanager is not running. (BZ#621652)
• The last owner field in "clustat -l" is now updated when a service fails over

due to node death. (BZ#639103)

• Previously, if a service was in the "starting" state, failover domain rules

would cause the service to relocate to a higher-priority node even if
"nofailback" was set. This no longer occurs. (BZ#672841)

As well, this update adds the following enhancements:

• rgmanager now sends signals to dbus when services change state. (BZ#657756)
• Independent subtrees may now be flagged as "non-critical," meaning they may

fail and have their components manually restarted without the entire service
being affected. (BZ#634277)

All users of rgmanager are advised to upgrade to this updated package, which
addresses these issues and adds these enhancements.
