I had an outage during live storage migration of a VM disk between two iSCS=
I.

Since the outage prevented Ovirt to cleanly remove stuff on the destination=
 iSCSI when the failure occurred, I think there's leftovers on the destinat=
ion iSCSI. The result is that any further attempt to live storage migrate t=
his VM disk fails with error "Cannot create Logical Volume"

How can I troubleshoot / fix this ?
