RHBA-2018:3844 - Bug Fix Advisory

Topic

Updated pacemaker packages that fix several bugs are now available for Red Hat Enterprise Linux 7.5 Extended Update Support.

Description

The Pacemaker cluster resource manager is a collection of technologies working together to maintain data integrity and application availability in the event of failures.

This update fixes the following bugs:

• Previously, you had to unmanage a guest node or bundle instance before cleaning, otherwise it was restarted. With this update, you can clean managed instances without problems. (BZ#1646349)
• Previously, if the cluster connection to a Pacemaker Remote node was moving from one cluster node to the other, any clone notifications required on the Pacemaker Remote node were not executed. With this update, the clone notifications are executed as expected. (BZ#1646346)
• Previously, clusters that used sbd for fencing could not configure guest nodes or bundles. Otherwise, the guest node or bundle instance was restarted if any resource running on it needed to contact the cluster services. Now, clusters with sbd can configure guest nodes and bundles without the described problem. (BZ#1646871)

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