====== Updating Cluster Configuration ======

Any time you need to update the cluster configuration, you must tell the other nodes that the file has changed.

First, backup the ''/etc/cluster/cluster.conf'' file. Edit ''/etc/cluster/cluster.conf'' and make the changes.

Tell The cluster system that the configuration file has changed:
<code lang=bash>
ccs_tool update /etc/cluster/cluster.conf
</code>
Check to see what version of the configuration the cluster is running:
<code lang=bash>
cman_tool status | grep "Config version"
</code>
Send the new cluster configuration to all the other cluster members:
<code lang=bash>
cman_tool version -r {new version number}
</code>
Log on to one of the other cluster members and check the version to ensure propagation has occurred.
