If you decide to create large (greater than 2TB) partition under your Linux box, you will figure out fdisk tool does not help you with it. The problem is the MBR (used by fdisk) has 2 TB addressable limit. The GUID partition table (GPT) is the solution for this issue. So, you need a) support of the GPT in Linux kernel (CONFIG_EFI_PARTITION should be defined and should be ‘y’) and b) GNU tool called parted.

Example how to use GPT and create large partition.

# parted /dev/sde
(parted) mklabel gpt
(parted) unit s
(parted) mkpart primary 2048 -1
(parted) quit
