RHBA-2013:1189 - Bug Fix Advisory

Topic

Updated cluster and gfs2-utils packages that fix one bug are now available for
Red Hat Enterprise Linux 6.

Description

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.

This update fixes the following bug:

• 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. (BZ#1001504)

Users of the Red Hat Cluster Manager and GFS2 are advised to upgrade
to these updated packages, which fix this bug.
