3.2TB RAID 5 and FC3

[Seth Dunn]

Hello,

I've just set up a disk array of 7 400GB SATA drives in a RAID5
configuration on a Fedora Core 3 install and it is showing that the
RAID5 only has ~397GB's of space.  The RAID is controlled by a
RocketRaid 1820A PCI-X card by Highpoint Technologies. Here is the
system information:
2.6.9-1.667smp #1 SMP Tue Nov 2 14:59:52 EST 2004 i686 i686 i386 GNU/Linux

Is there some kind of limit to how much disk space FC3 can address? Or
am I just missing something obvious?

Appreciate the help,
Seth
