How reproducible: 100% Steps to Reproduce: 1. Do live merge Actual results: Live merge fails Expected results: Engine should get in sync with qemu Additional info: Logs attached

Hi Markus, Can you please to live merge the snapshot that marked as illegal? Basically, if there is no 'real' storage issue and merge completed at vdsm/storage side, retrying live merge should recover from the failure - update the database and remove the snapshot.
