The problem is with the / partition.  However, on a fresh install of
Scyld Beowulf, the / partition is a ram disk, which means running out of
RAM may be the problem.  It won't try to put anything on the harddrive
of the slave node until you bring the nodes up with ramdisks and
partition them, then change the /etc/beowulf/fstab
