[Linux-HA] pingd problems

[fabiomm at br.ibm.com]

Hi Everyone!

I've send an e-mail before talking about a problem with DB2 resource. Now 
I'm sending this e-mail because I have problems with pingd.

I'm configuring a cluster over SLES 10 on xSeries Servers (x86_64) running 
heartbeat 2.0.5 to manage DRBD, IP, Filesystems and DB2 resources.

The node s0580crmdb2pr1 is the active node and the node s0580crmdb2pr2 is 
the passive node (where no resources are running).

The /etc/ha.d/ha.cf is configured as follows:


debugfile /var/log/ha-debug
logfile /var/log/ha-log
logfacility     local0
keepalive 2
deadtime 30
warntime 10
initdead 120
udpport 694
bcast   eth1
auto_failback on
watchdog /dev/watchdog
ping 10.226.0.100
respawn root /usr/lib64/heartbeat/pingd -m 200 -d 5s
apiauth ping gid=root uid=root
crm yes
node s0580crmdb2pr1 s0580crmdb2pr2

Here the IP address 10.226.0.100 is the gateway for both servers. My 
cib.xml have a place rule configured for pingd as follows:

     <constraints>
       <rsc_location id="place_db2pr1" rsc="group_db2pr1">
         <rule id="prefered_place_db2pr1" score="100">
           <expression attribute="#uname" 
id="745c2e82-e6cb-4c56-9611-797a2533a47d" operation="eq" 
value="s0580crmdb2pr1"/>
         </rule>
         <rule id="prefered_place_db2pr1_connected" 
score_attribute="pingd">
           <expression id="5042183e-b115-474e-9596-51d1581c0032" 
attribute="pingd" operation="defined"/>
         </rule>
       </rsc_location>
     </constraints>
   </configuration>
 </cib>

But everytime I start my heartbeat, I'm getting the following error 
messages:

And my crm_verify -LV shows errors related to pingd too:

s0580crmdb2pr1:~ # crm_verify -LV
crm_verify[30641]: 2007/05/23_16:19:22 WARN:

I'd like to ask you some help over this problem.
