7.302. cluster

Updated cluster and gfs2-utils packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The Red Hat Cluster Manager is a collection of technologies working together to provide data integrity and the ability to maintain application availability in the event of a failure. Using redundant hardware, shared disk storage, power management, and robust cluster communication and application failover mechanisms, a cluster can meet the needs of the enterprise market.

Bug Fix

BZ#1001504
Prior to this update, if one of the gfs2_tool, gfs2_quota, gfs2_grow, or gfs2_jadd commands was killed unexpectedly, a temporary GFS2 metadata mount point used by those tools could be left mounted. The mount point was also not registered in the /etc/mtab file, and so the "umount -a -t gfs2" command would not unmount it. This mount point could prevent systems from rebooting properly, and cause the kernel to panic in cases where it was manually unmounted after the normal GFS2 mount point. This update corrects the problem by creating an mtab entry for the temporary mount point, which unmounts it before exiting when signals are received.
Users of the Red Hat Cluster Manager and GFS2 are advised to upgrade to these updated packages, which fix this bug.

Bug Fix

BZ#982700
Previously, the cman init script did not handle its lock file correctly. During a node reboot, this could have caused the node itself to be evicted from the cluster by other members. With this update, the cman init script now handles the lock file correctly, and no fencing action is taken by other nodes of the cluster.
