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
node_up: Setting system clock.

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.
