You cannot create a Linux partition larger than 2 TB using f disk
command. It will not allow you to create a partition that is greater than 2 TB.
You can create it using parted utility. Please follow the below steps.
STEP 1:- Find out the current disk size.
[root@localhost ~]# fdisk -l /dev/sdb
Disk /dev/sdb: 4000.0 GB, 3999956729856 bytes
255 heads, 63 sectors/track, 486300 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/sdb doesn't contain a valid partition table
STEP 2:- Create 4 TB partition.
[root@localhost ~]#
parted /dev/sdb
GNU Parted 2.3
Using /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted)
STEP 3:- Create a new GPT partition table.
(parted) mklabel gpt
Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost. Do you want to continue?
Yes/No? yes
(parted)
STEP 4:- Set the default unit to TB.
(parted) unit TB
STEP 5:- Create a 4 TB partition.
(parted) mkpart primary 0 0
STEP 6:- Print the current partitions.
(parted) print
Model: ATA ST33000651AS (scsi)
Disk /dev/sdb: 4.00TB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 0.00TB 4.00TB 4.00TB ext4 primary
STEP 7:- Save changes and exit.
(parted) quit
Information: You may need to update /etc/fstab.
STEP 8:- Format the file system
[root@localhost ~]#
mkfs.ext4 /dev/sdb1STEP 9:- Mount the /dev/sdb1
[root@localhost ~]# mkdir /data
[root@localhost ~]# mount
/dev/sdb1 /data
[root@localhost ~]# df -H
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 391G 8.5G 363G 3% /
tmpfs 51G 0 51G 0% /dev/shm
/dev/sdb1
4.0T 211M 3.9T 1% /data
That’s it...
