Description Kaleb KEITHLEY 2015-05-07 13:09:17 UTC

+++ 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.

    Also send stderr output of `pcs resource {create,delete} $node-dead_ip-1`
    to /dev/null to avoid flooding the logs
