I have a cluster with two nodes, (db-sql1, db-sql3) and am trying to
configure STONITH over IPMI between them. I got my IPMI working fine,
and successfully tested to see if I can reboot the hosts using the same
command that is used in the driver's implementation (/usr/bin/ipmitool
-I lan -H ${ipaddr} -U ${userid} -P ${passwd} power reset).
I wrote the following XML configuration, from following the DTD
shipped with my version of the heartbeat software (CentOS, 2.1.3-21.1,
with kernel 2.6.18-53.1.14.el5):
<primitive id="db-sql1-shooter" class="stonith" type="external/ipmi"
provider="heartbeat">
<operations>
<op id="op-sql1-shooter-stop" name="stop" timeout="60s"/>
<op id="op-sql1-shooter-start" name="start" timeout="30s"/>
<op id="op-sql1-shooter-monitor" name="monitor" timeout="5s"
interval="10s"/>
</operations>
<instance_attributes id="df585416-074e-4955-a431-862f529e5b0b">
<attributes>
<nvpair name="hostname" value="db-sql1"
id="ee671a7b-9322-487e-8a19-689c85b0df65"/>
<nvpair name="ipaddr" value="db-sql1-ipmi"
id="2931750a-4304-48df-ac80-eb65619f1d33"/>
<nvpair name="userid" value="guess-who"
id="bbd8a701-b5aa-4a93-8c2e-7a838d5d3558"/>
<nvpair name="passwd" value="keep-trying"
id="3c6ce903-6e7f-45e7-86cb-b6c63b92ddb0"/>
</attributes>
</instance_attributes>
</primitive>
<primitive id="db-sql3-shooter" class="stonith" type="external/ipmi"
provider="heartbeat">
<operations>
<op id="op-sql3-shooter-stop" name="stop" timeout="60s"/>
<op id="op-sql3-shooter-start" name="start" timeout="30s"/>
<op id="op-sql3-shooter-monitor" name="monitor" timeout="5s"
interval="10s"/>
</operations>
<instance_attributes id="2a0dba3a-f121-4695-9ed2-5c3407d2d38f">
<attributes>
<nvpair name="hostname" value="db-sql3"
id="8a57bbb6-06f0-4916-a2fe-1ef54cba637f"/>
<nvpair name="ipaddr" value="db-sql3-ipmi"
id="9b544cea-8da5-4945-a30c-84320536463f"/>
<nvpair name="userid" value="guess-who"
id="bf1cb9f4-5af5-4cd3-906f-239d87b04e66"/>
<nvpair name="passwd" value="keep-trying"
id="0e784680-871e-4c55-bec5-9f534620c032"/>
</attributes>
</instance_attributes>
</primitive>
</resources>
Also, under Lars' recommendation, added two constraints to my constrait
set to prevent silly warnings during the start up of the stonith resources:
<rsc_location id="db-sql1-shooter-run-on-sql3" description="SQL1 shooter
must be at SQL3" rsc="db-sql1-shooter" node="db-sql3" score="+INFINITY"/>
<rsc_location id="db-sql3-shooter-run-on-sql1" description="SQL3 shooter
must be at SQL1" rsc="db-sql3-shooter" node="db-sql1" score="+INFINITY"/>
As the final result, crm_mon sees my cluster like this:
============
Last updated: Thu Nov 20 11:53:52 2008
Current DC: db-sql3.ripe.net (bdee5d1b-405a-4630-9836-66e8758e81f1)

complete
and crm_verify -VL points me to several warnings and a error that I am
unable to interpret correctly:
crm_verify[29480]: 2008/11/20_11:55:03 ERROR: unpack_rsc_op: Remapping

Compatability handling for failed op db-sql1-shooter_start_0 on
db-sql1.ripe.net
I am stuck, and need help. Don't know how to diagnose this, or which
part of the source code to read to find out what's going on. Any
suggestions, pointers, tips, tricks, or support will be highly appreciated.
Many thanks in advance.
Kind regards
