[Pacemaker] How to put delay in fence_intelmodular for one node only

[Gianluca Cecchi]

Hello,
I have a CentOS 6.5 based cluster with
pacemaker-1.1.10-14.el6_5.3.x86_64
cman-3.0.12.1-59.el6_5.2.x86_64

and configured pacemaker with cman integration.
The nodes are two blades inside an Intel enclosure.

At the moment my configuration has this in cluster.conf

  <fencedevices>
    <fencedevice name="pcmk" agent="fence_pcmk"/>
  </fencedevices>

and this if I run "pcs cluster edit"

      <primitive id="Fencing" class="stonith" type="fence_intelmodular">
        <instance_attributes id="Fencing-params">
          <nvpair id="Fencing-passwd-script" name="passwd_script"
value="/usr/local/bin/fence_pwd.sh"/>
          <nvpair id="Fencing-login" name="login" value="snmpv3user"/>
          <nvpair id="Fencing-ipaddr" name="ipaddr"
value="192.168.150.150"/>
          <nvpair id="Fencing-debug" name="power_wait" value="15"/>
          <nvpair id="Fencing-snmp_version" name="snmp_version" value="3"/>
          <nvpair id="Fencing-snmp_auth_prot" name="snmp_auth_prot"
value="SHA"/>
          <nvpair id="Fencing-snmp_sec_level" name="snmp_sec_level"
value="authNoPriv"/>
          <nvpair id="Fencing-pcmk_host_list" name="pcmk_host_list"
value="srvmgmt01.localdomain.local,srvmgmt02.localdomain.local"/>
          <nvpair id="Fencing-pcmk_host_map" name="pcmk_host_map"
value="srvmgmt01.localdomain.local:5;srvmgmt02.localdomain.local:6"/>
        </instance_attributes>
        <operations>
          <op id="Fencing-monitor-10m" interval="10m" name="monitor"
timeout="300s"/>
        </operations>
      </primitive>


If I want to set a delay on one of the two nodes to make it privileged in
case of split brain, what is the right place and how to put it?
Or do I have to decouple the fencing definition?

BTW: the fencing in general seems ok, but running crm_mon -1 on the two
nodes I have in my opinion confusing output (see below); is this expected?

[root at srvmgmt01 ~]# crm_mon -1
