Hello Dejan,
First of all thank you very much for your reply. I found that one of my node
is having the permission problem. There the permission of /var/lib/pengine
file was set to "999:999" I am not sure how!!!!!! However i changed it...
sir, when I pull out the interface cable i am getting only this log message:
Feb 18 16:55:58 node2 NetworkManager: <info> (eth0): carrier now OFF (device
state 1)
And the resource ip is not moving any where at all. It is still there in the
same machine... I acn view that the IP is still assigned to the eth0
interface via "# ip addr show", even though the interface status is 'down.'.
Is this the split-brain?? If so how can I clear it??
Because of the on-fail=standy in pgsql part in my cib I am able to do a
failover to another node when I manuallyu stop the postgres service in tha
active machine. however even after restarting the postgres service via
"/etc/init.d/postgresql-8.4 start " I have to run
crm resource cleanup <pgclone>
to make the crm_mon or cluster identify that the service on. Till then It is
showing as a failed action
crm_mon snippet

Is there any way to run crm resource cleanup <resource> periodically??
I dont know if there is any mistake in pgsql ocf script sir.. I have given
all parameters correctly but its is giving an error " syntax error" all the

Please help me out... should I reinstall the nodes again??
