Description Ala Hino 2016-02-17 12:01:23 UTC

Description of problem:
After successful live merge, if during host goes down after completion of live merge but before calling 'syncDbRecords', flow fails because 'syncDbRecords' calls vdsm to get image info.

This bug is to make sure we remove the call to vdsm outside of 'syncDbRecords'.

This patch should be backported to the ovirt-engine-3.6 branch. Setting the status back to POST.

Comment 3 Elad 2016-04-04 12:26:58 UTC

Tested the following on 2 builds:
rhevm-3.6.3-0.1.el6.noarch - doesn't contain the fix
rhevm-3.6.5-0.1.el6.noarch - contains the fix


1. Remove a snapshot lively
2. After DESTROY_IMAGE_CHECK completes, stopped vdsm

On the older build, the volume became Illegal and on the latest it got removed.
