I have 2 disks (@2TB) connected to my DELL Server using RAID 1 configuration. So, it has 4 TB in size. I want to create a partition with 4 TB in size. Using fdisk command, it only supports up to 2 TB disk size. So, I can’t use fdisk to partition my 4TB disk. Fortunately there is a simple way to solve this. We need a tool called Parted.
Steps to create partition on 4TB hard disk under Linux
I am using Debian 8 on this tutorial. I want to create a partition with more than 4 TB. Its 4.4 TB actually. All we need is the Parted package to be installed first. On Debian, you may install Parted using this command
su
apt-get install parted
Now we can start using it to partition the hard drive. In this example, my hard drive is recognized as /dev/sdb
parted /dev/sdb
Output:
GNU Parted 2.3
Using /dev/sdb
Welcome to GNU Parted! Type ‘help’ to view a list of commands.
(parted)
Create a new GPT disklabel
(parted) mklabel gpt
Set unit to TB
(parted) unit TB
Create 4 TB partition
(parted) mkpart primary 0.00TB 4.40TB
Print the partition
(parted) print
Output:
(parted) print
Model: DELL PERC 5/i (scsi)
Disk /dev/sdb: 4397GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Now quit parted
(parted) quit
Next we can start format the new partition. Enjoy
