Thanks for the input.

Thing is, I can't run any cman commands which include updating the conf file. 
Since I cannot start the cluster, I cannot run any cluster commands. Isn't 
that part of my problem, needing to figure out why/if cman is running?

It looks like cman won't start and because of that, fenced won't start either. 
There are plenty of errors in the logs which I've posted many times. I'm no 
longer sure what I'm looking for.

system-config-cluster has never worked on any of my machines using ANY version 
of RH. I've posted about that but have not found any answers.

Well, here's another paste of what's going on now...

First, how I'm starting my cluster, then some logging then my cluster.conf;

depmod -a
modprobe dm-mod
modprobe gfs
modprobe lock_dlm
ccsd
cman_tool join -t 120 -w
fence_tool join -t 120 -w
clvmd
vgchange -aly
mount -t gfs /dev/vgcomp/rimfire /var/www/

Then a snip of my logging;
