We’ve had very good experiences with DRBD, the Distributed Replicated Block Device which we’ve had running on a pair of machines for a couple of months now. So good in fact, that we invested in another pair of machines to run a similar setup for a good number of MySQL databases used internally. I have just completed the migration of those databases to the new servers, tweaking quite a number of Perl & PHP programs to connect to the new environment. All subsystems appear to be running a-ok. (Well, Michael: are you jealous? :-) )
