RHBA-2016:1662 - Bug Fix Advisory

Topic

Updated pacemaker packages that fix one bug are now available for Red Hat Enterprise Linux 6.

Description

The Pacemaker Resource 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:

• When stopping the cluster on all nodes by running "pcs cluster stop --all", resources that require the Distributed Lock Manager (DLM), such as Global File System 2 (GFS2) or clustered logical volumes, in some cases lost quorum before they were able to shut down. As a consequence, the stop operation became unresponsive. With this update, "pcs cluster stop --all" stops the cman service on all nodes only after Pacemaker has stopped those nodes. As a result, quorum is maintained while all resources are stopping, and the stop operation no longer hangs in the described situation. (BZ#1355738)

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