DRBD Replicas

[Dave Berry]

DRBD can add volumes on the fly, just need to reload it after it is
added to drbd.conf.   As far as a single node instance, you might just
want to have multiple instances setup and let them sit in the 'dark'.
Basically have a config that has 2 nodes but the second node will be
unreachable in the beginning.

I want to migrate everything to a new server (NEW) running 64-bit Debian as the dom0, then rebuild OLD with 64-bit Debian and use it to replicate the critical volumes from NEW.  So two questions:
