[ClusterLabs] Can't do anything right; how do I start over?

I've been trying a lot of things from the introductory manual.
I have updated the instructions (on my hardcopy) to the versions
of corosync etc. that I'm using. I can't get hardly anything to
work reliably beyond the ClusterIP.
So I start over -- I had been reinstalling the machines but I've
grown tired of that. So, before I start in on my other tales of woe,
I figured I should find out how to start over "according to Hoyle".
When I "start over" I stop all the services, delete the packages,
empty the configs and logs as best I know how. But this doesn't
completely clear everything: the drbd metadata is evidently still
on the partitions I've set aside for it.
Oh, before I forget, in particular:
# This is normally the *network* address of the
# interface to bind to. This ensures that you can use
# identical instances of this configuration file
# across all your cluster nodes, without having to
# modify this option.
bindnetaddr: I've tried using an address on ONE of the machines
and I've tried using an address that's on each participating machine,
thus a diff corosync.conf file for each machine (but otherwise identical).
What's the right thing? From the comment it seems that there should
be one address used among all machines. But I kept getting messages
about addresses already in use, so I thought I'd try to "fix" it.
This is my burn script.
Am I missing something? Doing it wrong?
