Description Liron Aravot 2017-03-30 08:40:43 UTC

Description of problem:
When creating a collapsed image the destination format is determined according to the target domain and the last volume in the chain.
The same format was used when moving a image without performing collapse when using the new spdm flows (4.1 data center) for each of the volumes instead of preserving the original format of each of them.


How reproducible:
Always

Steps to Reproduce:
1. Have a 4.1 data center with one iscsi domain and one nfs domain
2. Create a VM with one disk on the nfs domain.
3. Create a snapshot of the vm that includes the disk.
4. Move the disk to a block domain.

Actual results:
Both the base volume and the snapshot volume are created as COW volumes.


Expected results:
The base volume should be created as RAW while the snapshot volume should be created in the COW format.

I think that it will be a good idea to indicate in the doc text or/and in the wiki that also the volume type will be changed based on the volume format change.

Comment 2 Eyal Shenitzky 2017-05-01 04:36:19 UTC

Liron can you pls focus what should be checked here,
Should I check the disk format after the creation or after the move operation?

Comment 3 Liron Aravot 2017-05-03 22:36:44 UTC

Eyal, please check the destination image volumes.

 Verified with the following code:
----------------------------------
VDSM - 4.19.12-1.el7ev.x86_64
RHEVM - 4.1.2.1-0.1.el7

Steps to reproduce:
-------------------
1. Have a 4.1 data center with one iscsi domain and one nfs domain
2. Create a VM with one disk on the nfs domain.
3. Create a snapshot of the vm that includes the disk.
4. Move the disk to a block domain.
