Thanks.  I'll look into the fencing.  I'm using a cluster that was  
already up and running but having performance issues as a rough guide.  
  These are HP machines with ilo cards so I'll look into that method  
soon.  I am just looking at this cluster as a temp for now to move to  
so I can dig into the 'real' cluster. ;)

One small thing remains. I'm sure it isn't a drbd issue though.  I  
thought I was good to go with everything.  All of the commands to  
display various lvm data show up on the second node but there is  
nothing in the /dev directory.  I didn't realize this until I went to  
make the file system on the second node.  Any advice on where to look  
for that info?  I'll hit the RH site after lunch.

Thanks again.
