The format supported by fdisk is the ancient DOS  partition format.
I suspect you have reached its maximum size.

If this is the issue, I had the same problem on a Gentoo system some
time ago. From memory, I had to:
  - rebuild the kernel with CONFIG_PARTITION_ADVANCED=y and
    CONFIG_OSF_PARTITION=y (I think)
  - reboot in the new kernel so that it would understand
    an OSF partition
  - repartition the disc with gparted (not fdisk) to use the
    new partition format
  - proceed as normal thereafter

This is all from memory, but essentially I needed to change partition
table formats.
