You need to use a different kind of partition table.  Use 'parted' to
create a new label on the device, and use 'mklabel gpt' instead.  GPT
partition tables can support up to 128 partitions, so no need to
create extended partitions.

I believe most modern bootloaders understand gpt, I'm sure CentOS5
does.  You can create >2T volumes with GPT.

I'm not sure on the maximum size limit for GPT partition table
partitions, but I'm sure it's above 10T, since I've created volumes
that size.
