[Linux-HA] stonith with crm

[Peter Kruse]

Hello all,

How would I configure the stonith-devices when every node in the cluster
has it's own poweswitch?  When both nodes in a cluster are connected
to the same powerswitch this fragment works fine:

     <resources>
        <clone id="DoFencing">
          <instance_attributes>
            <attributes>
              <nvpair id="DoFencing-1" name="clone_max" value="2"/>
              <nvpair id="DoFencing-2" name="clone_node_max" value="1"/>
            </attributes>
          </instance_attributes>
          <primitive id="child_DoFencing" class="stonith" 
type="apcmastersnmp">
            <operations>
              <op id="DoFencing-monitor-1" name="monitor" interval="20s" 
timeout="40s" prereq="nothing"/>
              <op id="DoFencing-start-2" name="start" timeout="20s" 
prereq="nothing"/>
            </operations>
            <instance_attributes>
              <attributes>
                <nvpair id="child_DoFencing-1" name="ipaddr" value="apc"/>
                <nvpair id="child_DoFencing-2" name="port" value="161"/>
                <nvpair id="child_DoFencing-3" name="community" 
value="community"/>
              </attributes>
            </instance_attributes>
          </primitive>
        </clone>
     </resources>

If I understand correctly a "clone" will use the same configuration on
every node.  So what do I have to use if I need a different
configuration for each node so that
nodeA uses apcA to stonith nodeB
and
nodeB uses apcB to stonith nodeA
?
