RHBA-2016:1401 - Bug Fix Advisory

Topic

Updated rgmanager packages that fix several bugs are now available for Red Hat Enterprise Linux 6.

Description

The rgmanager packages contain the Red Hat Resource Group Manager, which is used for creating and managing high-availability server applications in the event of system downtime.

This update fixes the following bugs:

• With central processing mode enabled, when quorum was dissolved and regained, the rgmanager daemon stopped working on a surviving cluster node. With this update, the configuration tree is repopulated after quorum is regained. As a result, clustered services start up on the surviving cluster node as expected in the described scenario. (BZ#1335412)
• On cluster nodes where rgmanager was running, when the cman service was

stopped before rgmanager, rgmanager could exit unexpectedly. With this update, the cpg_lock()function has been fixed and rgmanager exits more gracefully in the described scenario. (BZ#1344640)

• When the clustat utility was run shortly after rgmanager started but before it completely finished initializing, the rgmanager daemon was susceptible to unexpected termination. This bug has been fixed and rgmanager now starts without crashing in this scenario. (BZ#1343345)

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