That can be done using heartbeat from linux-ha.org, plus DRBD for mirroring 
over the network.

I've used a similar setup for mail server (POP, IMAP, SMTP) with heartbeat
and ServeRAID for failing over the disks between the nodes. This has the
advantage of hardware fencing (two nodes are not allowed to use the disks 
at the same time).
