RHBA-2011:1487 - Bug Fix Advisory

Topic

An updated openais package that fixes two bugs is now available for Red Hat
Enterprise Linux 5.

Description

The Application Interface Specification (AIS) is an API and a set of policies
for developing applications that maintain services during faults. The OpenAIS
Standards Based Cluster Framework is an OSI-certified implementation of the
Service Availability Forum AIS. The openais package contains the openais
executable, OpenAIS service handlers, default configuration files and an init
script.

This update fixes the following bugs:

• When stopping the cman service on a cluster node shutdown, the groupd daemon

often exited with the "groupd: cpg_leave error retrying" error message, causing
OpenAIS to become unresponsive. As a consequence, the cluster node was not shut
down correctly. With this update, the underlying code has been modified to stop
cman correctly. Cluster nodes can now be shut down as expected. (BZ#752443)

• Under certain circumstances, if the system clock was changed on a cluster

node, cman could terminate unexpectedly on all cluster nodes, resulting in nodes
not being fenced. As a consequence, the cluster was not shut down gracefully and
had to be rebooted manually. With this update, the underlying code has been
modified to handle significant time changes. The cman service no longer
terminates and the cluster no longer fails. (BZ#754717)

All users of openais are advised to upgrade to this updated package, which fixes
these bugs.
