Manging the combination of nbd and mdraid is complicated.

complicated = drbd work?

I have been using drbd for a long time and it's quite easy to
implement, manage and use. The main purpose of all aplications I have
used it for, were high availibility and it works just fine. And it's
really cool to se it integrated with heartbeat, which will manage to
mount the partition on one or another node, according to your police
and nodes availibility.

plain disk performance for writes, while reads should be reasonably
close to the plain disk performance - drbd optimizes reads by just reading
from the local disk if it can.

 However, I have not used it with active-active fashion. Have you? if
yes, what is your overall experience?

Kind regards,
         Alex.
