The problem (I think) is because since heartbeat cannot mount the outdated partition, the commands in the /etc/ha.d/haresources are not executed. This means the network interface will not get the "fake" cluster IP address. Also I don't want to start exim/dovecot manually. I want them to start in a different configuration to preserve the drbd partition until the other node (not outdated) goes up. Maybe it's a Heartbeat issue, not a DRBD issue...
