Assuming of course that you dont need any kind of performance from your
filesystem drdb is indeed the answer.

ZFS snapshots can however be run on a per second basis which is quite neat!
What ever you choose to do you would probably want to use mysql binary
replication anyway so having a completely sync filesystem replica is
probably not too much of a problem.

I must point out that virtualisation made these kinds of problems mostly go
away (assuming of course that you have cash for some kind of High
Availability iSCSI device or something.
