NOTE: One of the major advantage over fdisk is, we can create huge partitions (2GB and more)
To accomplish this, you must use a gpt label (the GUID Partition Type) for your disk.
[root@localhost ~]# parted /dev/sda
GNU Parted 2.1
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.

NOTE: Changing the partition type will remove all partitions from your disk. All data on the disk
will be lost.
