Description Ala Hino 2016-09-04 20:13:03 UTC

Description of problem:
Image size (virtual size) is wrong if disk is extended before live merge

How reproducible:
100%

Steps to Reproduce:
1. create a VM
2. add a 1gb block disk
3. create a snapshot
4. extend the disk by 1gb
5. start the VM
6. Delete the snapshot

Actual results:
Virtual size is 1gb, actual size is 2gb

Expected results:
Virtual size is 2gb, actual size is 2gb

Comment 1 Sandro Bonazzola 2016-12-12 14:01:32 UTC

The fix for this issue should be included in oVirt 4.1.0 beta 1 released on December 1st. If not included please move back to modified.

Comment 2 Natalie Gavrielov 2016-12-27 13:00:44 UTC

Verified, 
rhevm-4.1.0-0.3.beta2.el7.noarch
ovirt-engine-4.1.0-0.3.beta2.el7.noarch
vdsm-4.19.1-1.el7ev.x86_64

Note that when deleting snapshot I get Failed to GetVolumeInfoVDS errors that are related to another issue.

Comment 3 Ala Hino 2016-12-27 13:03:14 UTC

The exception related to GetVolumeInfoVDS is expected. It is printed after we try to verify that the volume was deleted.

We are planning to remove the exception trace from the log file.
