enbd-client manual says:
To do mirroring to a couple of different remote server targets,
add a second "+host2:ctrlport2 -n nchan2" entry on the command
line just after the first. Note the "+" before the second host-
name. Writes will then be mirrored to both targets, but reads
will still come preferentially from the first target. If a mir-
ror component goes offline, writes to it will be suppressed
until it comes back online, when it will be resynced from the
remaining component in the background. Only the blicks dirtied
while it was offline are written during the resync, so this is
fast.
But this does not work and code does not seem to exist for this behaviour,
I guess that the solution is two nbd-clients + two /dev/ndX in raidtab?
