Rene, VDSM can't read the storage domain's metadata, the problem is that
vdsm tries to read the metadata using 'dd' command which applies to the
old version of storage domains as in the new format the metadata is
saved as vg tags. Are you using storage domain version lower that V2?
Can you attach the full log?
Saggi, any thoughts on that?

Hi,
ihave rebootet my iscsi device without mainenance mode. Now it is
inactive. When I want to reactivate it again it fails. What can I do?
Depends why it fails, vdsm log can help.
You can check whether or not you're connected from the hosts to the
iscsi target or reconnect using:
iscsiadm -m discoverydb --discover -t st -p your_iscsi_server_fqdn
iscsiadm -m node -T your_target_name -l
Than try to activate it.
