[Users] Master domain locked, error code 304

Thu Apr 25 07:08:56 UTC 2013

Hi,
Your problem is that the master domain is locked, so the engine does not send connectStorageServer to the vdsm host,
and therefore the host does not see the master domain.
You need to change the status of the master domain in the db from locked while the host is in maintenance.
This can be tricky and not very recommended because if you do it wrong you might corrupt the db.
Another, safer, way that I recommend is try to do connectStorageServer to the masterSD from vdsClient on the vdsm host and see what happens, it might solve your problem.
