I recently did some searching on the topic of high availability and
the service replication and stumbled across DRBD, some kind of
network RAID-1. DRBD mirrors partitions between two machines in a
completely transparent way. I have no idea if and how well this
works (the mailing-list traffic suggests that it does work), but I
find the idea brilliant. It makes rsync unnecessary and even works
for services that don't have any replication functionality at all.

You can find some descriptions as well as a download link at the
following URL:

If you decide to give it a try, I'd be very interested to hear from
your experiences.
