You read the notes here about startup/shutdown? http://sources.redhat.com/cluster/doc/usage.txt To shutdown, you umount all fs's on all nodes, fence_tool leave on all nodes, then leave the cluster on all. To leave the cluster without quorum getting in the way use 'cman_tool leave remove'. To start up, have all nodes join the cluster with cman_tool join, then have all nodes join the fence domain with fence_tool join, then start other things.
