My array size is 4.5TB. It's just one large single RAID5, so it's slightly
less than 4.5TB. So, what you're saying then is to either put a small single
HD to install CentOS, or make the array smaller than 4.5TB. I could easily
make something much smaller, say ~1TB, install CentOS on that. Once that's
finished, create the rest of the array as another array at the size that I
need. Could use LVM to stitch it all together...

I'll give this a try, thanks for the help.
