--- Comment #1 from Pranith Kumar K <pkarampu at redhat.com> ---
How reproducible:
Consistently

Steps to Reproduce:
1.Create disperseVol 2 x (4 + 2) and Enable MDCache and GNFS on it
2.Mount the volume from single server to 2 different client
3.Create 512 Bytes of file from 1 client on mount point
4.Take lock from client 1.Lock is acquired
5.Try taking lock from client 2.Lock is blocked (as already being taken by
client 1)
6.Release lock from client1.Take lock from client2
7.Again try taking lock from client 1.

Actual results:
Lock is being granted to client1

Expected results:
Lock should not be granted to client 1 as lock is currently being held by
client 2
