[Pacemaker] Configuration for fence_kdump

[Junko IKEDA]

Hi,

I'm trying to run fence_kdump with Pacemaker 1.1.7.
There are only two actions, off/metadata, for fence_kdump,
so I set pcmk_monitor_action="metadata" to substitute metadata for monitor.

# fence_kdump -o metadata
<?xml version="1.0" ?>
<resource-agent name="fence_kdump" shortdesc="Fence agent for use with kdump">
<longdesc>The fence_kdump agent is intended to be used with with kdump
service.</longdesc>
<parameters>
        <parameter name="nodename" unique="1" required="0">
                <getopt mixed="-n, --nodename" />
                <content type="string" />
                <shortdesc lang="en">Name or IP address of node to be
fenced</shortdesc>
        </parameter>

<snip>

        <parameter name="usage" unique="1" required="0">
                <getopt mixed="-h, --help" />
                <content type="boolean" />
                <shortdesc lang="en">Print usage</shortdesc>
        </parameter>
</parameters>
<actions>
        <action name="off" />
        <action name="metadata" />
</actions>
</resource-agent>


Here is my configuration;

# cat fence_kdump.crm
property no-quorum-policy="ignore" \
        stonith-enabled="true" \
        startup-fencing="false" \
        stonith-timeout="120s" \
        crmd-transition-delay="2s"

rsc_defaults \
        resource-stickiness="INFINITY" \
        migration-threshold="1"

primitive stonith-1 stonith:fence_kdump \
        params \
        pcmk_host_check="dinamic-list" \
        pcmk_monitor_action="metadata" \
        nodename=bl460g6c \
        timeout=10

primitive stonith-2 stonith:fence_kdump \
        params \
        pcmk_host_check="dinamic-list" \
        pcmk_monitor_action="metadata" \
        nodename=bl460g6d \
        timeout=10

location location-1 stonith-1 \
        rule -INFINITY: #uname eq bl460g6c
location location-2 stonith-2 \
        rule -INFINITY: #uname eq bl460g6d



Unfortunately, fence_kdump has failed at its start procedure.

# crm_mon -1

It seems that default "off" action is called at the start (monitor_0) operation.
Is there any misunderstanding in my configuration, especially around
"pcmk_monitor_action"?
I was wondering if you could give me some advice.


By the way, I created cluster.conf manually.

# cat /etc/cluster/cluster.conf
<?xml version="1.0" ?>
<cluster name="ossvert" config_version="1" >
 <clusternodes>
  <clusternode name="bl460g6c" nodeid="1">
   <fence>
   </fence>
  </clusternode>
  <clusternode name="bl460g6d" nodeid="2">
   <fence>
   </fence>
  </clusternode>
 </clusternodes>
 <fencedevices>
  <fencedevice name="kdump" agent="fence_kdump" />
 </fencedevices>
 <rm>
 </rm>
</cluster>

# rpm -qa | grep fence-agents
fence-agents-3.1.5-10.el6.x86_64

# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.2 (Santiago)
