The only thing I like better than writing howtos for our software is reading howtos for our software written by someone else. Especially when they’re really really good. Mark Schoonover has written an excellent introduction to setting up Heartbeat with MySQL and DRBD.

Great DRBD/Heartbeat/MySQL article. I notice that the author recommends connecting the 2 independent servers with a dedicated Ethernet cable. I wonder if it can be done over a WAN without decent bandwidth available?

Nope. Linux clustering isn’t built for split site setups just yet. DRBD can handle split site configurations just fine, but you would not run this as one Heartbeat/Pacemaker (or Corosync/Pacemaker, for that matter) cluster.
