Description Idan Shaby 2017-01-19 15:54:31 UTC 
Description of problem:
When trying to sparsify a direct lun that is attached to a vm, a UI exception is shown.

Version-Release number of selected component (if applicable):
6968ff23b74862046be1f91201138b0d79a336ef

How reproducible:
100%

Steps to Reproduce:
1. Create a vm.
2. Create a direct lun as one of the vm disks.
3. Click on "Sparsify" when selecting this disk.

Actual results:
UI exception

Expected results:
Should work/be blocked/fail with an error.

Additional info:
It seems to be a class cast exception because of a cast from Disk to DiskImage, so I guess that it will happen with cinder disks, too.
I, personally, don't know what the right behavior should be with disks other than images, I'll leave it to you to decide.

I'd block it.
Comment 2 sefi litmanovich 2017-02-01 11:44:07 UTC 
Verified with rhevm-4.1.0.3-0.1.el7.noarch.
1. Create a vm.
2. Created a vm with direct lun as one of vm's disks.
3. Sparsify option in UI is disabled.
4. Via REST API sparsify action fails - The error message is 'Internal error' too general, opened a bug for this: https://bugzilla.redhat.com/show_bug.cgi?id=1418255
