RHBA-2013:0017 - Bug Fix Advisory

Topic

Updated cmirror packages that fix two bugs are now available for Red Hat
Enterprise Linux 5.

Description

The cmirror packages provide a user-level utility for managing cluster
mirroring. Cmirror is needed for LVM (Logical Volume Manger) based mirroring
(RAID1) in a cluster environment.

This update fixes the following bugs:

• Prior to this update, requests for information about the health of the log

device were processed locally. As a consequence, the cluster mirror daemon could
not detect log device failures on remote machines. With this update, the
information is requested from the cluster so that log device failures are
detected and processed as expected. (BZ#711594)

• Prior to this update, the cmirror utility could fail to initialize the mirrors

correctly when successively activating and deactivating cluster mirrors. As a
consequence, any I/O operation to the device and further LVM commands became
unresponsive.This update modifies the underlying code so that the problem only
occurs after a large number of iterations. (BZ#806919)

All users of cmirror are advised to upgrade to these updated packages, which fix
these bugs.

Solution

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