Eh, no, you don't. Just point nbd-server to the file on the remote node,
and connect the client. That's exactly what the nbd-client is supposed
to do.
Of course the semantics will be slightly different (you can't write past
the end of a block device, while you can write past the end of a file,
etc.), but apart from that, nbd seems like exactly what you need.
Or am I misunderstanding something?
No, I am not know the semantics about write/read to block device. Actually, I need to write[from] block to[from]
the device which nbd-client provide. But I do not know howto , maybe i should resort to LDD. :-)
Thanks for your advance.
