Single Node GFS

Pretty much just for testing, here's a single node cluster.conf:

<cluster name="clust" config_version="1">
  <clusternodes>
    <clusternode name="gfs1.terran.lan" votes="1" nodeid="1">
      <fence>
        <method name="single">
          <device name="fence_dev" nodeid="gfs1.terran.lan"/>
        </method>
      </fence>
    </clusternode>
  </clusternodes>
  <fence_devices>
    <fence_device agent="fence_xvm" name="fence_dev"/>
  </fence_devices>
</cluster>
