I currently have two ubuntu servers running Heartbeat and DRBD. The servers are directly connected with a 1000Mbps crossover cable on eth1 and have access to an IP camera LAN on eth0.
Now, let's say that one node is down and the remaining functional node is booting after having been shut down. The node that is still functioning won't start up heartbeat and provide access to the drbd resource from a cold boot. I have to manually restart heartbeat by sudo service heartbeat restart to get everything up and running.
How can I get it to start fine from a cold start, when only one server is present?
Here is the ha.cf:
debugfile /var/log/ha-debug
logfile /var/log/ha-log
logfacility none
keepalive 2
deadtime 10
warntime 7
initdead 60
ucast eth1 192.168.2.2
ucast eth0 10.1.10.201
node EMserver1
node EMserver2
respawn hacluster /usr/lib/heartbeat/ipfail
ping 10.1.10.22 10.1.10.21 10.1.10.11
auto_failback off

If I restarted heartbeat at this point… the resources heartbeat controls would start up fine…. please help!

As commanded in the comments here is my initial suggestion in answer form.
If you run a recent enough Ubuntu version (10.04 or newer) you should ditch Heartbeat completely and use Corosync and Pacemaker instead. While this is not a answer or solution to your particular problem it will, as you have seen, make your problem simply disappear.
A great introductory article about Pacemaker was written in Linux Journal and Clusters from Scratch is a great starting point for getting Corosync and Pacemaker up and running. For Ubuntu 10.04 please use the PPA for the official stable backported cluster stack: https://launchpad.net/~ubuntu-ha-maintainers/+archive/ppa
The old Heartbeat stack has many conceptual shortcomings and has been obsoleted for so long now it is not worth trying to debug the problems that are bound to arise if you use it today. Corosync and Pacemaker have been created for this exact reason and they work just so much better than Heartbeat, which isn't even a resource manager, ever could.
