Create a dist-replica volume and start it. 2. Create a snapshot of this volume. 3. Create a clone from this snapshot. 4.

COMMIT: http://review.gluster.org/12406 committed in release-3.7 by Rajesh Joseph (rjoseph) ------ commit c11e3232963d28b4cdf73b694d82f7b6ed38894f Author: Avra Sengupta <asengupt> Date: Thu Oct 15 16:08:03 2015 +0530 snapshot: Fix snapshot clone postvalidate BackPort Of http://review.gluster.org/#/c/12364/ In glusterd_snapshot_clone_postvalidate(), we were deleting snap object and snap vol, by looking up snapname. Hence, it was deleting the orignal snapshot from which the clone was being created Instead it should fetch the clonename, the respective clone vol, and its corresponding snap object, and delete them. Also glusterd_snap_remove(), needs to differentiate a clone snap object from a snaphsot snap object, as in case of a clone snap object, we don't have any persisted data in /var/run/gluster/snaps/ and hence is shouldn't try to delete anything there.
