I had that problem when I was using an adaptec aic79xx adapter, using a
new LSI-Logic one fixed the problem for me. Could it be a limit with
your controller/controller driver?

I am trying to create a 3.2TB partition on my Raid 5. Is there a
document that could help?
I have a 3ware 9500 controller and 8 *500GB sata drives configured
into a single RAID 5 array.
I am running linux 2.6.16 with the 3ware drivers compiled into the
kernel.
I've tried a couple of different means to create the partition and
format the file system with xfs without success (or confidence that I
haven't done something wrong).
1. FDISK
I've tried fdisk on the array to create the partition; but it forces
me enter the number of cylinders before letting me create the
partition. I enter the largest number of cylinders since I'm not sure
how to calculate the correct cylinder number across an 8 disk RAID 5
array.
I then create the partition starting at 0 (or whatever the default
was) and ending at 3500GB.
Once the partition is created this way, I can mkfs.xfs; but I'm a
little hesitant to use this since I input and arbitrary cylinder number.
Thoughts on what to use for the correct cylinder count with fdisk?
2. PARTED
I've tried to use parted without any success. Here is what I've tried
and the errors I get.
> parted
parted> mklabel gpt
parted> mkpart primary 0 3500GB
parted> quit
ok - the partition now exists. If I use ext2 everything works ok.
however, when I run
> mkfs.xfs /dev/sda1
the file system is formated but is truncated to to 2TB.
Any advice/pointers on how to partition and format a 3.2TB raid 5
array would be much appreciated.
Thanks,
Chris....
