Verify the Deactivated snaps doesnot showup in .snaps at the client
[root at dhcp42-244 ~]# gluster snapshot activate snapvol1
Snapshot activate: snapvol1: Snap activated successfully
[root at dhcp42-244 ~]# gluster snapshot activate snap2vol1
Snapshot activate: snap2vol1: Snap activated successfully
[root at dhcp42-244 ~]#

Client:
=======
[root at dhcp43-190 ~]# mount -t glusterfs 10.70.42.244:/testvol1 /mnt/testvol1
[root at dhcp43-190 ~]#
[root at dhcp43-190 testvol1]# cd .snaps
[root at dhcp43-190 .snaps]# ls
[root at dhcp43-190 .snaps]#
2. Performed lookup on .snaps directory in a loop and see there is no hang.
3. After activating the snaps for the volume:
[root at dhcp43-190 .snaps]# ls
snap2vol1 snapvol1
[root at dhcp43-190 .snaps]#
TC2:
1. Deactivate the snaps and perform ls on the .snaps
[root at dhcp43-190 .snaps]# ls -l
total 0
[root at dhcp43-190 .snaps]#
After activating the snaps again the snashots are visible at the client:
[root at dhcp43-190 .snaps]# ls
snap2vol1 snapvol1
[root at dhcp43-190 .snaps]#
