Updated clustermon packages that fix a bug and add an enhancement are now available for Red Hat Enterprise Linux 6.
The clustermon packages are used for remote cluster management.
Previously, the clustermon tool failed to shut down nodes if the user had mounted a GFS2 file system that was not listed in the /etc/fstab file. This was caused by clustermon relying on the rgmanager tool and the GFS2 init scripts to unmount all file systems, but the cluster stack would not stop properly if the user mounted the file system manually. This has been fixed: clustermon now ensures that there are no cluster file systems mounted and then attempts to stop the cluster stack.
The "get_cluster_schema" function call has been added to allow users to easily get the XML cluster schema content.
All users of clustermon are advised to upgrade to this updated packages, which resolves this bug.
