chkconfig --level 2345 fenced on

(for starters). You *must* have fencing.

To make two services share it:

  <resources>
    <clusterfs ... name="mygfs" />
  </resources>
  <service name="foo">
    <clusterfs ref="mygfs"/>
  </service>
  <service name="bar">
    <clusterfs ref="mygfs"/>
  </service>
