4.10. Starting the Cluster Software
After you have propagated the cluster configuration to the cluster nodes you can either reboot each node or start the cluster software on each cluster node by running the following commands at each node in this order:
service ccsd start
service cman start (or service lock_gulmd start for GULM clusters)
service fenced start (DLM clusters only)
service clvmd start
service gfs start, if you are using Red Hat GFS
service rgmanager start
Start the Red Hat Cluster Suite management GUI. At the Cluster Configuration Tool tab, verify that the configuration is correct. At the Cluster Status Tool tab verify that the nodes and services are running as expected.
