Bug 1438252

Created attachment 1268209 [details]
engine & vdsm logs

Description of problem:
After cold migration/move of Vm's disk+snapshots to V4 storage domain , migrated snapshots disks are still with qcow2_v2.
Disk is upgraded to qcow2_v3 as expected.


Version-Release number of selected component (if applicable):
Engine:
ovirt-engine-4.1.1.6-0.1.el7.noarch

VDSM:
4.19.6-1


How reproducible:
100%


Steps to Reproduce:
1. Create DC + cluster on v3 + 2 new storage domains
2. Create a VM with thin disk and create 2 snapshots
3. Upgrade the cluster+DC from v3 to v4
4. Verify that the snapshot images are version 0.10
5. Move all the disks of the VM to Version 4 Domain
6. Verify that the snapshot images have been upgraded to version 1.1
    
Actual results:
After migration of a Vm's disk+snapshots to V4 storage domain snapshots disks are with qcow2_v2.
Disk is upgraded to qcow2_v3.

Expected results:
After migration of a VM's disk+snapshots to V4 storage domain, I expect to get disk & snapshots disk are with qcow2_v3


Additional info:
Storage migration took place at 2017-04-02 14:32:39 & was successful.
