Description Tal Nisan 2015-12-30 14:01:25 UTC

Description of problem:
After performing an alignment scan the command fails upon return with a ClassCastException

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


How reproducible:
100%

Steps to Reproduce:
In a non active VM with disks on block domains right click on one of the disks and select "Scan Alignment"

Actual results:
Alignment succeeds in VDSM but the command fails in the Engine with "Alignment scan of disk '%diskname%' failed."

Expected results:
If the alignment succeeded in VDSM we should see in the Engine that the command succeeded
