RHBA-2014:0358 - Bug Fix Advisory

Topic

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

Description

The Corosync packages provide the Corosync Cluster Engine and C Application
Programming Interfaces (APIs) for Red Hat Enterprise Linux cluster software.

This update fixes the following bug:

• On a paused node after resume, the corosync utility could not discern whether

other nodes' Closed Processed Group (CPG) clients were terminated, and
incorrectly defined them as alive. CPG membership was thus inconsistent. With
this update, corosync properly updates its internal information about other
nodes' CPG clients. As a result, killed CPG clients are properly removed from
the internal structures, and CPG membership is now equal between nodes.
(BZ#1080102)

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