You *must* change the cluster name!

Other things to look out for:

 * 'uname -n' must match something in cluster.conf.  If it doesn't,
   you need to edit /etc/init.d/cman: right before line 44
   ("load_modules()"), put:

      cman_join_opts+="-n <name_from_cluster.conf>"

   This must be done on each cluster member!

 * chkconfig --del openais (if it's not already disabled)
