Updated clustermon packages that fix several bugs are now available for Red Hat Enterprise Linux 6.
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.
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.
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.
All users of clustermon are advised to upgrade to these updated packages, which fix these bugs.
