So.. I am having the same problem, and tried to get through it a different way, but I'm not sure what's going on...

I basically put in a "throw away" 200g drive I just had laying around that I used as the OS install disk, and then used 3x 1tb drive in a HARDWARE raid 5 to give me 2tb to share over the FC.

I was hoping the boot disk wouldn't be counted, and it would only count the HW Raid5 against the 2tb limit, but no such luck..

I couldn't get my MoBo to boot off of the HW Raid (I hoped to just remove the 200g and use a partition on the HW Raid for boot) so I decided if I create only a 1.8tb partition, and waste 200g on my RAID, since its a HARDWARE raid, it should NOT be able to count the unused space, and it would add up to 2tb...

Unfortunately, even after clicking rescan, it STILL says I'm over 2tb... SO.. just to make SURE I wasn't just slightly over 2tb with the 1.8 + 200gb, I re-created my RAID partition as 1.6tb, so I should be right around 1.8tb "visible" by the OS, but alas... it STILL says I'm over 2tb...

There's GOT TO BE A WAY.. What am I missing here? is there ANY way to get an enumeration of the disks it's seeing, so that I can see if it's just caching old information somehow, or if it's hopeless because it's seeing the three 1tb drives that are the components of the 1.6 tb Raid-5???

If it helps, I'm using a SiliconImage 6-port Hardware SATA Raid card.
