Description of problem:
=======================
I have a 3 node setup with about 6 volumes as below(the name represents vol
type, and all volumes are distributed-*)
cross3
distrep
ecvol
ecx
rep2
rep3

I mounted one of the volume rep2 using fuse mount on one of the nodes itself
say n1
and did a restart of glusterd on the same node. I saw that the volume is
getting unmounted
