Description Fabio Massimo Di Nitto 2013-11-25 14:06:28 UTC 
Description of problem:

This bug is intended to track all bugs encountered in HA nfs-server deployment scenario testing for RHEL 7.

Testplan: TBA

Draft of HA nfs-server deployment scenario: 
http://rhel-ha.etherpad.corp.redhat.com/PRD-HA-nfsserver
Comment 1 michal novacek 2014-10-22 09:43:23 UTC 
The scenario can be tested _without_ locks and works correctly in the following
scenarios:

Basic operations, including the following steps:
    * create shared lvm
    * setup cluster
    * setup hanfs group
    * check that the following action are possible and verify that they has
        been performed correctly: start, stop, move, destroy

Failover operations, including tho following on node running hanfs:
    1/ node suddenly fails
    2/ its network becomes inavailable
    3/ switch fails (nodes sudenly stops seing each other)

----

The same tests could not have been done with locking of the files turned on because of the following bug:
[https://bugzilla.redhat.com/show_bug.cgi?id=1120850] unable recover NFSv3 locks NLM_DENIED_NOLOCK
Comment 3 michal novacek 2014-12-09 09:34:53 UTC 
bz1159234 is now the blocker of the scenario tests as described in its comment 10.

Summary: /var/lib/nfs is not correctly umounted due to the change in systemd units that does not require it anymore. It prevents stopping of the volume group group and the node is restarted.
