[ovirt-users] Re: storage domain sync problem and fail to run vm after change LUN mapping

Ok, so what is the correct way too fix this? After change multipath configuration, should I restart engine or put something on maintenance (and then reactivate it) to be sure that every value in the DB is fixed? Can I do this change one host at time or it's better to do it on all hosts simultaneously (global maintenance)?
