researcher turned in a couple of old Sun Fire X4150 machines. I am
tasked with turning them into a sandbox for students to play
around with slurm, condor, etc. I asked a co-worker to install
ubuntu server on them but at the time, I didn't know each machine
had 4 147G disks. I believe she did a standard ubuntu install and
just put it on the first disk.

Should I start over and configure RAID or should a use the 3 empty
disks to configure a DNFS? I have to configure a distributed
network file system anyway so that when a student logs into one
machine, he gets the same home dir as if he logged onto the other.
I usually set up gluster and then make the gluster volume their
home directory.
<br>
<br>
So I could just use the 3 empty disks on each machine as a gluster
home directory space and then do triple replication.

<font face="DejaVu Sans">I've not tried, but I wonder if you could
use fsarchiver to save to a file. Then you could put things in a
RAID5 and restore.<br>
<br>
Would be an interesting exercise.<br>
