Hi again,
no way to make fence working on RHEL6 :
I have 3 nodes in cluster and the status before the test is (crm_mon) :
Online: [ node1 node2 node3 ]
restofencenode1 (stonith:fence_ipmilan): Started node2
restofencenode2 (stonith:fence_ipmilan): Started node3
restofencenode3 (stonith:fence_ipmilan): Started node1
But when I do force an error on node2 (if down on heartbeat IF) so that
node3 resource restofencenode3 fences the node2 with fence_ipmilan, it
does not make the job, I can see that node2 is UNCLEAN (due to no more
heartbeat)
Node node2: UNCLEAN (offline)
Online: [ node1 node3 ]
restofencenode1 (stonith:fence_ipmilan) Started [ node2 node3 ]
restofencenode2 (stonith:fence_ipmilan): Started node3
restofencenode3 (stonith:fence_ipmilan): Started node1
but it is very strange that restofencenode1 appears started on node2 and
node3 whereas it should only be started
on node 3, due to the constraints I set :
<rsc_location id="loc1-restofencenode1" node="node2"
rsc="restofencenode1" score="+INFINITY"/>
<rsc_location id="forbiddenloc-restofencenode1" node="node1"
rsc="restofencenode1" score="-INFINITY"/>
<rsc_location id="loc1-restofencenode2" node="node3"
rsc="restofencenode2" score="+INFINITY"/>
<rsc_location id="forbiddenloc-restofencenode2" node="node2"
rsc="restofencenode2" score="-INFINITY"/>
<rsc_location id="loc1-restofencenode3" node="node1"
rsc="restofencenode3" score="+INFINITY"/>
<rsc_location id="forbiddenloc-restofencenode3" node="node3"
rsc="restofencenode3" score="-INFINITY"/>
but it seems that it is because of problems on the use of fence_ipmilan
that crm_mon displays something not really right ...
but I can also see in syslog :
node3 daemon info stonith-ng [807]: info: can_fence_host_with_device:
*restofencenode2 can not fence node2: dynamic-list
*
I have quite the same configuration as before with external/ipmi on
fc12, except all around the fence_ipmilan parameters which differs,
and it worked fine on fc12, did someone here has already tried the
pacemaker fencing with fence_ipmilan agent ?
My restofencenode2 record in cib :
<primitive class="stonith" id="restofencenode2" type="fence_ipmilan">
<instance_attributes id="restofencenode2-instance_attributes">
<nvpair id="restofencenode2-instance_attributes-ipaddr"
name="ipaddr" value="BMC address of node2"/>
<nvpair id="restofencenode2-instance_attributes-login"
name="login" value="mylogin"/>
<nvpair id="restofencenode2-instance_attributes-passwd"
name="passwd" value="mypasswd"/>
<nvpair id="restofencenode2-instance_attributes-action"
name="action" value="reboot"/>
</instance_attributes>
<meta_attributes id="restofencenode2-meta_attributes">
<nvpair id="restofencenode2-meta_attributes-target-role"
name="target-role" value="Started"/>
</meta_attributes>
</primitive>
If someone has an idea ...
Thanks a lot
Regards
Alain
