resolved?
yes, thanks.
I had to restart also host itself to regain access to SD....
One note about the SD: it is iSCSI configured as sw iscsi target in HA with
Pacemaker and drbd.
I had a problem on one node and apparently this was not so transparent to
oVirt host.
I didn't have time to check more deeply....
