All,

Here is some new information it looks like the nodes can't mount /dev/hda1.  Any
ideas on this?  Sometimes I get this message before the faild to mount message:

mount: mount point /rootfs/beoboot does not exist

# more /var/log/beowulf/node.1

Looking at the disk I see:

Now in order to get the floppies to boot we had to add this line to the fstab
file and comment everything else out.  Am I missing something in the fstab?  

#/dev/ram3       /       ext2    fs_size=65536   0       0

# cat fstab
# This file is the fstab for nodes.
# One difference is that we allow for shell variable expansions...
#
# Variables that will get substituted:
#  MASTER = IP address of the master node.  (good for doing NFS mounts)
# Note that the "noauto" and "user" options are meaningless here.

#/dev/ram3       /       ext2    fs_size=65536   0       0
/dev/hda1       beoboot         ext2    defaults        0 0
/dev/hda2       swap            swap    defaults        0 0
/dev/hda3       /               ext2    defaults        0 0
none            /proc           proc    defaults        0 0
none            /dev/pts        devpts  gid=5,mode=620  0 0
$MASTER:/home   /home           nfs     defaults        0 0
#

I see that there isn't a /home on the disk so I'm not sure how the home
filesystem get mounted from the master.
