RHBA-2015:1205 - Bug Fix Advisory

Topic

Updated cluster 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.

This update fixes the following bug:

• Under certain circumstances, large quantities of uevent messages sent from the

kernel were capable of flooding the gfs_controld and dlm_controld daemons,
causing them to lose a part of the messages. In some cases, this caused the
recovery process of Global File System (GFS) mount points and Distributed Lock
Manager (DLM) lockspaces to become unresponsive, and the system therefore needed
to be rebooted. With this update, gfs_controld and dlm_controld handle large
amounts of uevent messages more reliably. As a result, the recovery of GFS mount
points and DLM lockspaces no longer hangs. (BZ#1234442, BZ#1233534)

Users of cluster are advised to upgrade to these updated packages, which fix
this bug.

Solution

Before applying this update, make sure all previously released errata relevant
to your system have been applied.
