RHBA-2011:0900 - Bug Fix Advisory

Topic

An updated cman package that fixes one bug is now available for Red Hat
Enterprise Linux 5.

Description

The Cluster Manager (cman) utility provides user-level services for managing a
Linux cluster.

This update fixes the following bug:

• Previously, quorum disk heuristic timers in a cluster functioned improperly.

As a consequence, if the heartbeat network malfunctioned, the cluster nodes
could end up fencing each other in a non-deterministic way. With this update,
the problem with the timers has been addressed and the bug no longer occurs.
(BZ#707053)

All users of cman are advised to upgrade to this updated package, which fixes
this bug.
