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:

ccs_tool update /etc/cluster/cluster.conf

Check to see what version of the configuration the cluster is running:

cman_tool status | grep "Config version"

Send the new cluster configuration to all the other cluster members:

cman_tool version -r {new version number}

Log on to one of the other cluster members and check the version to ensure propagation has occurred.
