RHBA-2012:1439 - Bug Fix Advisory

Topic

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

Description

The fence-agents packages provide the Red Hat fence agents to handle remote
power management for cluster devices. The fence-agents allow failed or
unreachable nodes to be forcibly restarted and removed from the cluster.

This update fixes the following bugs:

• The speed of fencing is critical because otherwise, broken nodes have more

time to corrupt data. Prior to this update, the operation of the
fence_vmware_soap fencing agent was slow and could corrupt data when used on the
VMWare vSphere platform with hundreds of virtual machines. This update fixes a
problem with virtual machines that do not have a valid UUID, which can be
created during failed P2V (Physical-to-Virtual) processes. Now, the fencing
process is also much faster and it does not terminate if a virtual machines
without an UUID is encountered. (BZ#872620)

All users of fence-agents are advised to upgrade to these updated packages,
which fix this bug.

Solution

Before applying this update, make sure all previously-released errata relevant
to your system have been applied.
