RHBA-2018:3513 - Bug Fix Advisory

Topic

Updated resource-agents packages that fix two bugs are now available for Red Hat Enterprise Linux 7.5 Extended Update Support.

Description

The resource-agents packages provide the Pacemaker and RGManager service managers with a set of scripts. These scripts interface with several services to allow operating in a high-availability (HA) environment.

This update fixes the following bugs:

• Previously, the rabbitmqctl cluster_status command read cached cluster status from disk and returned 0 when mnesia service was not running. For example, this happened if rabbitmqctl stop_app was called, or the service paused during partition due to the pause_minority strategy. As a consequence, RabbitMQ might have returned cached status from disk. With this update, RabbitMQ now gets cluster status from mnesia during monitor-action. As a result, the described problem no longer occurs. (BZ#1641945)
• Previously, monitor action succeeded on all nodes when the RabbitMQ message broker got into a partitioned state without triggering a fencing action. As a consequence, the cluster remained partitioned indefinitely. With this update, monitor action now fails when node is in minority partition. As a result, nodes in minority partition get fenced as expected. (BZ#1641948)

Users of resource-agents are advised to upgrade to these updated packages, which fix this bug.
