The correct answer is "dd if=/dev/hda1 of=hdb1 bs=1024". This doesn't
care what is one the drive, even win 95 (known by experience), and it will
act like a perfect mirror.
The proper thing to do is to nfs export everything on one system, make a
boot disk that can mount the nfs drive, partition/mount the new drive, and
edit any specific info (hostname and ip) all by a simple boot script.
It's way above my head, but when set up right, would be almost as easy to
do 100 as it is to do 5. I think this is what the titanic team did (in
the lj article). I don't think they used redhat's easy method.
