Hi, <br><br>I&#39;ve setup a two node cluster for testing using the &quot;Clusters from Scratch - Apache, DRBD and GFS2&quot; guide. I&#39;ve set it up and fail over works like a charm, but I want one of the nodes to be a master; and fail back resources to the master when it comes back up. At the moment, the resource stays at the failed back node. configs:<br>
