formatting and mounting a 32 TB RAID 50 disk

I want to know how to format a 32 TB drive. What program should I use and what filesystem?
The largest drives I ever had to map before are 2-3 TB and I always used fdisk for formatting. But fdisk is not working for drives larger than 2.1 TB.

I would prefer that the whole volume is mounted as a single logical drive. We need to store large files in it, some may well pass 4TB.

I have an HP ProLiant DL380p Gen8 server in my administration and configured two 1TB disks as a 1TB system drive and ten 4TB disks into a 30 TB drive using RAID 50. I installed Ubuntu Server 12.04.

UPDATE:
I used parted to relabel the partition table to GUID Partition Table (GPT) from msdos which is default for Ubuntu Server 12.04

parted /dev/sdb mklabel gpt

I then used parted to create an ext4 partition, which I later relabeled to xfs with: mkfs.xfs /dev/sdb1. The rest went smoothly.

You need to use the GUID Partition Table (GPT) on such a large disk. In Linux, there are two families of programs that support GPT:

The libparted library, which is used by parted, GParted, and several others, supports both GPT and the older MBR.

The GPT fdisk family (gdisk, sgdisk, and cgdisk) is a GPT-only tool. It's installed as part of the gdisk package in Ubuntu.

In addition, fdisk has recently gained GPT support, but even Ubuntu 14.04 uses a version that's old enough that it lacks this support.

As to filesystems, XFS, JFS, and ext4fs can all handle such a big volume. So can Btrfs, but it's so new that I don't think I'd recommend it. Chances are this is a pretty important project, so you should research the differences between these filesystems for your specific needs.
