Description of problem: ======================= While listing snapshot using gluster snapshot list command, it displays "Volume <snap_name> Does not exist" which is confusing Version-Release number of selected component (if applicable): ============================================================= glusterfs 3.4.0.snap.dec03.2013git How reproducible: ================ always Steps to Reproduce: ================== 1.Create a volume and start it 2.Mount the volume and create snapshot gluster snapshot create volume1 -n SNAP1 -d "this is snap of volume1" snapshot create: SNAP1: snap created successfully 3.List the snapshot gluster snapshot list Volume Name : volume1 Number of snaps taken : 1 Number of snaps available : 255 Snap Name : SNAP1 Snap Time : 2013-12-12 06:09:03 Snap ID : abc9bd33-6b19-4cd8-b1f7-6b6b7572a1a1 Volume SNAP1 Does not exist Actual results: ============== Snapshot list output displays "Volume SNAP1 Does not exist" which is confusing Expected results: Additional info:
Till now we were saving the snap info in volume list itself(as snap is also a volume), hence while listing the snapshot it used to show the snap as a volume ( Volume <snap_name> Does not exist ). Now we thought of having a separate list for snaps in order to get rid of the confusion. This issue has been fixed in the patch http://review.gluster.org/#/c/6614/
verified with build: glusterfs-3.4.1.snap.jan15.2014git-1.el6.x86_64 As mentioned in the fix, the snap volumes are not listed by any volume list/info/status command. Because of which the snap volume is not listed as <Volume <snap-name> Does not exist> during the crawl in snap list command.
