What do you mean by "remove" ? If you want to fence server1, you can : - use the command "fence_node server1" on server2 - stop server1 - use the command "fence_ack_manual -n server1" on server2 - restart server1 to make it join the cluster again If you want to really remove a server from the cluster, you can remove the entry from the cluster.conf file (for instance with the command "ccs_tool delnode server1") If you want to stop one node : you can simply stop the services, in the right order ?
