RHBA-2012:0292 - clustermon bug-fix update

Synopsis

clustermon bug-fix update

Type/Severity

Bug Fix Advisory

Topic

Updated clustermon packages that fix several bugs are now available for Red Hat Enterprise Linux 5.

Description

The clustermon packages are used for remote cluster management. The modclusterd service provides an abstraction of cluster status used by conga and by the Simple Network Management (SNMP) and Common Information Model (CIM) modules of clustermon.

This update fixes the following bugs:

  • Prior to this update, under certain circumstances, outgoing queues in inter-node communication of the modclusterd service could grow over time. To prevent this behavior, the inter-node communication is now better balanced and queues are restricted in size. Forced queue interventions are logged in the /var/log/clumond.log file. (BZ#618321)

  • Prior to this update, execution of external programs (such as /usr/sbin/clustat) from within the modclusterd daemon or ricci's helper program, modcluster, could make these unresponsive. In such a case, processes depending on the programs could also become unresponsive or indicate an error. For example, in tools like luci, the affected node could be listed as having communications problems, or the cluster creation could become unresponsive. Patches have been applied to address this issue, and deadlocks no longer occur when executing external programs. (BZ#736814)

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

Solution

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