My goal is to run HA pair without having to buy an external storage device. (This is for a class on clustering.) (And I really don't mind adding other commands to rc.local. If I am designing a system that is dedicated to a "family" of applications, like DRBD, Heartbeat, etc., then rc.local seems a good place for their initialization to be.) Alex
