nbd / hot plug

hi guys, i was thinking about nbd problems with server disconnection /
client disconnection
it's not like a SATA disk hot plug?
for example unplug the disk (SATA) = unplug the network card
could md raid work with it?
i tried but i should run
mdadm fail / remove / add
to get nbd back in array, it's right?

Yes, nbd with md/raid works fine. If the nbd connection gets broken,
the nbd component of the array will fail, you can then remove it and
re-add it.
