RHBA-2012:0750 - Bug Fix Advisory

Topic

Updated clustermon packages that fix several bugs are now available for Red Hat
Enterprise Linux 6.

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#742431)

• When the clustermon utility was used to get the cluster schema from the

server, the schema was returned in an invalid format, preventing further
processing. This bug has been fixed and clustermon now provides an exact copy of
the schema in the described scenario. (BZ#794907)

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