[Vinoth Narasimhan]

Hi Guys,

I just installed the latest heartbeat,pacemaker and corosync as per the
guidelines from the below link

http://www.clusterlabs.org/wiki/Install#READ_ME_FIRST

I am able to successfully configure the heartbeat and corosync and start it
as well.

But when i tried to add the resource i am getting the error from python.

[root at CHE-PSS-072 lib64]# crm configure
