[ovirt-users] Does my Storage Domain crashed or is this iSCSI LUN's a problem?

26 Jan 2015

      Hi guys,

I'm trying to run one of my storage domains, which experienced failure.
Unfortunately, I meet a very nasty error (Storage domain does not exist).

Could someone tell me, how to try to restore this domain?

P.S.
It's an oVirt 3.4.2-1.el6
