[Linux-HA] RE: One-way failover?

[Alexey Zilber]

John,
I've been playing around with monit+heartbeat, and I have it mostly working,
unfortunately I'll need to code up some extra scripts that return proper
status for each group in monit.   Otherwise, heartbeat just checks to see if
monit itself is running, and doesn't start any process groups.

For now I'll probably just disable heartbeat auto-startup on the primary
node..
