[ovirt-users] Re: oVirt + TrueNAS: Unable to create iSCSI domain - I am missing something obvious

FYI the fix is to check the "Disabled Physical Block Size Reporting" box in the extent window. Note in testing this I had to delete the extent and create a new one, toggling the switch on and then restarting the iscsi service didn't seem to do it, maybe the client cached something.
