Parted command to create partition larger than 2tb

Linux desktop user generally uses small hard disk and partition, but on server you need a large partition. For example, you cannot create 4TB partition size (RAID based) using fdisk command. It will not allow you to create a partition that is greater than 2TB.

To solve this problem use GNU parted command with GPT. It supports Intel EFI/GPT partition tables. Partition Table (GPT) is a standard for the layout of the partition table on a physical hard disk. It is a part of the Extensible Firmware Interface (EFI) standard proposed by Intel as a replacement for the outdated PC BIOS, one of the few remaining relics of the original IBM PC. EFI uses GPT where BIOS uses a Master Boot Record (MBR).

Linux create 3TB partition size

One of my clients has Raid 5 Array -7×500GB hard disks to store large data. To create partition start GNU parted as follows:
# parted /dev/sdx
Output:

GNU Parted 1.8.1
Using /dev/sdx

Creates a new GPT disklabel i.e. partition table:
mklabel gpt
Create 3TB partition size:
mkpart primary 0 3001G
Quit and save the changes:
quit
Use mkfs to format file system:
# mkfs.ext3 /dev/sdx1
