[Linux-HA] heartbeat 2.0.2 + stonith

[announces at genos.es]

Hi

I'm trying to configure a stonith device using heartbeat 2.0.2. The main
goal is to use my own stonith plugin to control some PDU devices.
I use the ssh stonith device but it always says:

lrmd[13468]: 2005/10/04_11:46:08 debug: Will send the stonith RA
operation to stonithd: ssh start
stonithd[13345]: 2005/10/04_11:46:08 ERROR: Invalid config info for ssh
device.
lrmd[13468]: 2005/10/04_11:46:08 ERROR: sending stonithRA op to stonithd
failed.
lrmd[13346]: 2005/10/04_11:46:08 WARN: mapped the invalid return code
152.


My cib.xml is:

 <cib>
   <configuration>
     <crm_config>
       <nvpair id="suppress_cib_writes" name="suppress_cib_writes"
value="false"/>
       <nvpair id="transition_idle_timeout"
name="transition_idle_timeout" value="60000"/>
       <nvpair id="stonith_enabled" name="stonith_enabled"
value="true"/>
       <nvpair id="symmetric_cluster" name="symmetric_cluster"
value="true"/>
       <nvpair id="no_quorum_policy" name="no_quorum_policy"
value="stop"/>
     </crm_config>
     <nodes/>
     <resources>
       <group id="apache_group">
         <primitive id="ip_resource" class="ocf" type="IPaddr"

             </attributes>
           </instance_attributes>
         </primitive>
         <primitive id="apache" class="lsb" type="apache2"/>
         <primitive id="lampara_stonith" class="stonith" type="ssh">
           <attributes>
             <nvpair name="hostlist" value="heartbeat1" />
           </attributes>
         </primitive>
       </group>
     </resources>
     <constraints>
       <rsc_location id="run_apache_group" rsc="apache_group">
         <rule id="pref_run_apache_group" score="100">
           <expression attribute="#uname" operation="eq"
value="heartbeat1" />
         </rule>
       </rsc_location>
     </constraints>
   </configuration>
   <status/>
 </cib>



Node names are "heartbeat1" and "heartbeat2"

How do I pass the "config info" for ssh stonith? I try with attribute
"hostlist" but it doesn't work... I have also tried with null device but
it says the same error message.
And then, how can I make my own plugin? It will be so simple as sending
some data to a TCP port like this: 

echo "shutdown-server"| netcat 172.16.74.14 10010


Thanks
