qcow format requires a filesystem below and since iscsi is a raw block
device you cannot create qcow files directly on the target. If you want
be to able to make both raw and qcow disk formats your option is to
export two targets from your san. One target is used for lvm-raw disks
and on the other target you create a filesystem for qcow based disks.
Only downside to this is that you cannot use such a disk for shared
storage (the storage will be treated as a local disk on the proxmox
