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@srvmgmt01 ~]# crm_mon -1
