Sample PCS configuration session
Run the following commands on all three nodes in the cluster (nodes are named f1, f2 and f3). This will create the corosync.conf files for the cluster.

[root@f2 pcs]# ./pcs cluster configure my_cluster_name f1 f2 f3
[root@f3 pcs]# ./pcs cluster configure my_cluster_name f1 f2 f3
Then run the following command on all three nodes in the cluster, to start corosync and pacemaker.
[root@f1 pcs]# ./pcs cluster start
