DRBD needs something as a 'low level device' which works like a block
device, i.e. a raw partition, md, lvm.
You would need to umount any fs first, and configure DRBD with metadata
'external' on the partition(s).

Your 500 GB need to go over the network connection anyway. Maybe you
take out the harddisk and put it into the target system for a faster copy.
