need help with setting up cluster

I am wondering if someone could help me. I am new to clustering which is why I chose caos.
Anyways the problem I am having is after I configure perceus, vnfs, and slurm. one of my nodes
will boot up to a login screen, but I can not login. The other node I tried to boot up will get the perceus bootloader screen but then gives me an error stating that it could not connect to the perceus master.

I am using the 64bit version the latest build from caos 1.0, and perceus 1.5, vnfs 1.08.1.

I had one other question two about slurm. When I configured slurm, I got this message:

The host name of the master node points to the local loop network device ( This will need to be reset to the primary op address of this system for slurm to schedule jobs properly.

I am not sure where to reset this at. The guide does no explain any of this.

I really need to get this going but am not having any luck so far.

If the other nodes are clones of the master node, check their /etc/hosts file. For the master node, it is OK to have the address, but for the other nodes, the master node should be listed with the address of its interface, not localhost.
