RE: [Linux-cluster] RHSCv4 2-node cluster hangs whilestartingfenced



Hi All,

Thanks a lot for your support.. 

My cluster is running smooth now but I need to change what Dave and Lon
suggests. I will re-configure as Dave says and if not second option he
suggested. Lon's guide read the same configuration but I didn't get  
<method name="1"/>
	<device name="HPiLO_node1"/>
	<!-- ^^^^^^^^^^^^^^^^^^^^-->  ======> this part
</method>

What does it means?

Please advice as I needed to understand to setup RHCS

Thanks in advice

- Hirantha

The point is that Node1 should have the device(s) controlling *Node1* in
its fence block.  Node1's fence block is *not* this:

    "What devices can Node1 use to fence off Node2...?"

... it is:

    "What devices can other nodes use to fence off Node1...?"

I'm going to go out on a limb and state that I think HPiLO_node2 is the
iLO card residing in Node2, and HPiLO_node1 is the iLO card which is in
Node1.  If that is the case, I suspect you need to have your config look
like this:

<clusternodes>
	<clusternode name="node1" votes="1">
		<fence>
			<method name="1"/>
				<device name="HPiLO_node1"/>
				<!-- ^^^^^^^^^^^^^^^^^^^^-->
			</method>
		</fence>
	</clusternode>
	<clusternode name="node2" votes="1">
		<fence>
			<method name="1">
				<device name="HPiLO_node2"/>
				<!-- ^^^^^^^^^^^^^^^^^^^^-->
			</method>
		</fence>
	</clusternode>
</clusternodes>
<cman expected_votes="1" two_node="1"/>
<fencedevices>
	<fencedevice agent="fence_ilo" hostname="10.10.10.1"
                login="Administrator" name="HPiLO_node1"
		passwd="RWE232WE"/>
	<fencedevice agent="fence_ilo" hostname="10.10.10.2"
                login="Administrator" name="HPiLO_node2"
		passwd="QWD31D4D"/>

Fence levels are sets of procedures to try for fencing.  Most users (you
included) should only ever need 1 fence level. :)
