Yes that was all done just like I"ve done it before.  I setup a 14TB 
array in FC2 and never had this problem.  I did find the solution on the 
debian mailing list.  Turns out that I had to run 'vgmknodes' after 
creating the lvm for it to symlink in /dev correctly.  After that, it 
worked just fine.
