I have to say, if it takes "less than a week" to set up a cluster when
you already know how to do it... I suspect it'll take me "less than a
week" to have a working clone of heartbeat v1 -- and that's without
doing any programming. I mean, how hard can it be to have set up mon to
ping the other node and fire up a few scripts when it stops responding.
Let's face it: a 2-node active/passive cluster on xover (or serial)
cable can only really guard against hardware failure. In which case 99%
of the time you don't need to care about split brain and everything that
comes with that.
