A 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.
root at cartan:~# fdisk -l | grep G
Disk /dev/sda: 146.7 GB, 146685296640 bytes
Disk /dev/sdb: 146.7 GB, 146685296640 bytes
Disk /dev/sdc: 146.7 GB, 146685296640 bytes
Disk /dev/sdd: 146.7 GB, 146685296640 bytes
Disk /dev/mapper/cartan--vg-root: 133.5 GB, 133513084928 bytes
Disk /dev/mapper/cartan--vg-swap_1: 12.9 GB, 12880707584 bytes
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.
So I could just use the 3 empty disks on each machine as a gluster home
directory space and then do triple replication.
