RHBA-2012:0554 - cmirror bug fix update

Synopsis

cmirror bug fix update

Type/Severity

Bug Fix Advisory

Topic

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

Description

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.
