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