The output now looks like:

enbd-client  7356: client (-1) will set size 1229375668224
enbd-client  7356: BLKGETSIZE failed
enbd-client  7356: sending ENBD_SET_SECTORS64 2401124352
enbd-client  7356: ENBD_SET_SECTORS64 succeeded
enbd-client  7356: client (-1) set device size 1229375668224
enbd-client  7356: #2511 setkernelnbd: Failed set size 1229375668224 on fd 4: 
File too large
enbd-client  7356: client (-1) sets session slots to 0-1
enbd-client  7356: #3416 introduction: Failed/5: File too large
enbd-client  7356: #3441 introduction: client (-1) introduction bails out on 
storage3:1035
enbd-client  7356: client (-1) waits 5s after 7s before retry 1

BTW: The device which i could access for testing has only 1.1 TB capacity. But 
the error does also happen at this size.
