I have a 15 x 300 array under ext3 on the 3ware 9550SX-16ML. You need to
use parted to create a GPT type partition system. MS-DOS style(default)
does not allow you to create over 2 TB arrays. Then you can create your
4 TB partition. You'll always have to use parted instead of cfdisk/fdisk
when playing with partitions, as cfdisk/fdisk will see the "fake"
partition table GPT uses to point to the real table.
You'll also need large block device support compiled into your kernel.
This implies a 2.6.x kernel.
Your other option is using the 2 TB carving of the 3ware card, and then
using software raid or LVM to put that back together into a larger chunk.
Also, you won't be able to boot off this, as lilo/grub do not support
booting from GPT style partitions.. I put a 16 meg CF card on a CF to IDE
adapter, and put /boot on there, with my lilo boot loader running from the
CF card.
Also, what hard drives are you using? You should be aware that currently
Maxtor Maxline III's(7v300F0's) do not work properly due to a firmware
bug. The current version shipping is VA111630, an update is available to
VA111670 which merely reduces the frequency of timeouts that get the drive
kicked out from the array. I will be getting VA111680 from Maxtor as soon
as I find the time.
