large partition problem

[don fisher]

I have a RAID 5 system that I am having trouble mounting. When I use 
fdisk to make the partition, it does not make one large enough. When I 
use sfdisk I get the 2249.9 GB, 2249900163072 bytes partition expected.

I tried to create both both ext3 and XFS file systems. When I create 
the ext3 file system, the following appears:

mke2fs 1.38 (30-Jun-2005)
warning: 479 blocks unused.

Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
6221664 inodes, 12419072 blocks
620977 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=4294967296
379 block groups
32768 blocks per group, 32768 fragments per group
16416 inodes per group
Superblock backups stored on blocks:
         32768, 98304, 163840, 229376, 294912, 819200, 884736, 
1605632, 2654208,
         4096000, 7962624, 11239424

Writing inode tables: done
Creating journal (32768 blocks): done

The maximum file system blocks looks correct. When I mount the device 
and execute df I get:

/dev/sda1             48895340    184324  46227108       1% /usr2

Not even 50GB:-(

My kernel is built to accommodate file systems larger than 2TB. My 
previous system was 1.58TB and worked correctly. It appears that when 
I exceeded 2TB something broke.

Any advice would be appreciated. Apologies in advance if the solution 
is obvious. It is a bit late here.
