+++ This bug was initially created as a clone of Bug #1216039 +++

Description of problem:

We have seen below issue while testing open/lock states recovery after IP
failover in nfs-ganesha HA setup - 

The cluster has not been put into grace before IP fails over. There seem to be
a timing issue there. "pcs constraint colocation order" seem to have not
completely solved it.

--- Additional comment from Kaleb KEITHLEY on 2015-05-07 09:08:27 EDT ---

yes, there's a race between setting grace and failing over the virt IP.
