[Beowulf] Weird CentOS Install Problem

I have had the same problem. You should double-check that the non-80 GB 
volume has a GPT type partition table set. To see your current partition 
table setting, run parted /dev/<your_volume> and then "print." You 
should see something like this:

parted) p
Disk geometry for /dev/sde: 0.000-2626094.625 megabytes
Disk label type: gpt
Minor    Start       End     Filesystem  Name                  Flags
1          0.017 2626093.625  ext3

I've noticed that Red Hat's Anaconda will create an MS-DOS partition 
table on the disk even though MS-DOS partition tables cannot support 
greater than 2 TB volumes. You can use "parted" to change it to GPT via 
the mklabel option. Then you can create the ext3 file system.
