'pcs cluster report' output

Description of problem:
I'm recently getting 'nfsidmap[4540]: Failed to add child keyring: Operation
not permitted' with NFS cluster HA testing. I found out this problem while
testing nfs (re-)locking of file while nfs server is moving from node to node.

Version-Release number of selected component (if applicable):
nfs-utils-1.2.3-68.el6.x86_64
kernel-2.6.32-613.el6.x86_64

How reproducible: always

Steps to Reproduce:
1. have running pacemaker ha nfs server
2. on the client node outside of cluster mount nfs from server and exclusively
    lock file
3. move nfs server to another node

Actual results: long time to determine lock acquisition/denial + failed to add...

Expected results: short time to acquire/deny

Additional info:
It seems that acquiring/denying lock takes up to 10s where it previously was
less than 1s (RHEL-6.8-20160205.n.0 snapshot).
