Hi Ian, I really like to understand how it happened, there are several ways to fix this issue, please send us engine and vdsm logs for a start. as for fixing the issue, we will probably have to perform some manual intervention on either engine data-base (preferable) or storage metadata. its a bit complex, and might cause other things to fail if not doing carefully, so its your call.
