Hello,

i'm new in this list. I have to show no understanding for the fence
daemon. Why should i use this ? My issue:

I have a cluster with two nodes. And i want to use the dbrd 8.0 or
higher for a primary/primary state. There was a problem with fencing. 
When the first node is down, the second node can not be rebootet by
root, because the shell says: 
fence_tool: waiting for cluster quorum

Here my cluster.conf
<?xml version="1.0"?>
<cluster name="mail-intern" config_version="1">
<cman two_nodes="1" expected_votes="1"/>
        <clusternodes>
	 <clusternode name="mail-i01" nodeid="1">
	   <fence>
	     <method name="human">
	       <device name="maili01"	ipaddr="10.1.0.1"/>
             </method>
           </fence>
          </clusternode>
         <clusternode	name="mail-i02"	nodeid="2">
	    <fence>
	      <method name="human">
	        <device	name="maili02"	ipaddr="10.1.0.2" />
	      </method>
	    </fence>
	  </clusternode>
	 </clusternodes>
	 <fencedevices>												        <fencedevice name="human"	agent="fence_ack_manual"/>					        </fencedevices>												</cluster>

Is the behavior right or could i configure this. If that is so, i cannot
reboot the second node when the first isn't in the cluster, is so ?

Thank for all your time

Enrico
