Description Roman Hodain 2015-04-13 15:58:03 UTC

Description of problem:
When a disk with a snapshot in the preview mode is moved to a different storage, the volume which is the preview one is not migrated and is removed from the source storage domain.

Version-Release number of selected component (if applicable):
vdsm-4.16.8.1-8.el6ev.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Create VM with one disk
2.Create snapshot
3.Make preview
4.move the disk to a different SD

Actual results:
the preview volume is removed, but it remains in DB

Expected results:
The preview is migrated as well or the operation is not allowed.

It should just be blocked.

Tal, since this is your week, please take a look, and either fix it or reassign at your discretion.

Comment 3 Tal Nisan 2015-04-21 10:17:23 UTC

Storage migration both live and cold is now blocked by CDA when one or more of the VMs attached to a disk are during a snapshot preview or during a snapshot creation

Comment 6 Ori Gofen 2015-05-17 13:26:08 UTC

Verified on 3.6 master, the operation is now Blocked
