Hi,
am I right to assume that DRBD uses each server's single NIC?
You could probably do better by adding a NIC to each server, connect
them back-to-back (crossover cable) and use that link for DRBD only.
As an aside, was it customary with 8.0 to have assymetric configurations
on the nodes? You may want to upgrade to 8.3 either way ;-)
HTH,
Felix
