Bug Fix Advisory cmirror bug fix update

Advisory: RHBA-2012:0554-1
Type: Bug Fix Advisory
Severity: N/A
Issued on: 2012-05-10
Last updated on: 2012-05-10
Affected Products: RHEL Cluster-Storage (v. 5 server)

Details

Updated cmirror packages that fix one bug are now available for Red Hat
Enterprise Linux 5.

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

This update fixes the following bug:

* The cluster mirror daemon sends information between cluster nodes to keep the
mirror log state consistent. Information about the state and health of the
mirror and its devices is gathered as needed from the daemon. Some of the
information does not change after the device has reached a certain state, for
example when the mirror becomes "in-sync", while other information can change,
for example the health of the log device in response to a failure. To limit the
amount of such requests and reduce the load on the network, processing of
information which cannot change is done locally. Previously, also requests for
information regarding the health of the log device - which ultimately controls
the fault handling behavior of the mirror - were processed locally, which caused
the daemon to miss the failure of the log device on a remote machine. With this
update, the information is requested from the cluster so that log device
failures are detected and processed as expected. (BZ#816973)

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