Description RHV bug bot 2018-06-01 08:14:09 UTC

+++ This bug is a downstream clone. The original bug is: +++
+++   bug 1497355 +++
======================================================================

Description of problem:

The snapshot creation of a Live Storage Migration hung and timed out on the engine side. However, the engine then continued on with CloneImageGroupStructureVDSCommand and VmReplicateDiskStartVDSCommand, etc.

The result was that the LSM effectively failed, with the disk still residing in the source storage domain. However, volumes were created in the target storage domain, which caused a subsequent LSM to fail.


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

RHV 4.1.6
RHVH 4.1.6
  vdsm-4.19.31-1.el7ev
  

How reproducible:

Benny, can you take a look please?

Tentitively targetting for 4.2.
If there's something safe enough to backport to 4.1.z, we should do that, but I'm not commiting on such a fix unless we see what the upstream fix contains.
