I have a 2 node cluster with pgsqlms and sbd fencing. 

I tested the failover by resetting the VM running the postgresql master, it
promoted the other node.

When i started pacemaker on fenced node i get this error:

Instance "pgsqld" controldata indicates a running primary instance, the
instance has probably crashed

One second later it changes to :

                Unexpected state for instance "pgsqld" (returned 9)

Then node is fenced again.



What is the correct way of recovering failed master?
