2.9.7 Propagate the Configuration File to the Cluster Nodes

After you have created or edited a cluster configuration file on one of the nodes in the cluster,

you need to propagate that same file to all of the cluster nodes and activate the configuration.

For example, propagate the cluster.conf file to all nodes in the cluster:

ccs -h HA02.SH --sync --activate

2.9.8 Start the CMAN Service

Start the cman service from all nodes in the cluster with the following command:

service cman start

Figure 14. Start the cman Service

Note: The Network Manager needs to be stopped using the service NetworkManager

stop and chkconfig NetworkManager off commands. The cluster cannot be started until

these two commands have been completed.

Run command cman_tool nodes to list all nodes in the cluster.

Figure 15. Check the Cluster Configuration

The cluster is now operational.
