Should this work if I simply stop httpd on danvers (node 1)?

It deals with DRBD, but the heartbeat section can still be applied to what you are playing around with. http://www.howtoforge.com/drbd-8.3-third-node-replication-with-debian-etch Best regards, Brian > I'll probably think of more questions right after I hit the send key. > Dimitri Yioulos wrote: > Hello to all. > > I'm a Linux-HA newbie.
