Before I ask this, I'd like to say that I *have* gone through this list 
archives
and looked through the install docs that come with the Scyld CD...

When I first booted my nodes, they came up as 'unavailable'.  After reading, I
figured out that the fstab was referring to a non-existant hard drive in the
nodes.  So I changed them to use /dev/ram3:

/dev/ram3     /        ext2   fs_size=65536  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

Now, the node shows up as 'down'.  I get this in my node log:

setup_fs: Checking /dev/ram3 (type=ext2)...
setup_fs: FSCK failure.
setup_fs: Creating ext2 on /dev/ram3...
Couldn't find ext2 superblock, trying backup blocks

<Large paragraph about running e2fsck>

options=gid=5,mode=620)
setup_libs: Copying libraries to node 0...
Library copy to node 0 failed.  (rootfs=/rootfs)


Now I can ping the node, but that's it.

Master is: K6II/533 w/ 128M RAM
Nodes are: K6II/500 w/ 64M RAM

Thanks,
Wyatt
