+           -- gluster snapshot create <snap1> <vol-name(s)>

+           create multiple gluster snapshots

+        10. Do a snapshot info to see all the snapshots information
+        11. Verify that the IO is not hindered
+        12. Arequal all the bricks in the snap volume
+        13. Cleanup
