First, check the disk status before the partition

] # fdisk-l

Disk / dev/vda:107.4 GB, 107374182400 bytes, 209715200 sectors

Units = sector of 1 * 512 = 512 bytes

2. Fdisk format disk / sev/sdb as one disk

] # fdisk / dev/vdb

Welcome to fdisk (util-linux 2.23.2).

The changes remain in memory until you decide to write them to disk.

Think twice before using the write command.

Device does not contain a recognized partition table

Create a new DOS disk label using the disk identifier 0x8a058557.

Command (enter m for help): M

Command operation

A toggle a bootable flag

B edit bsd disklabel

C toggle the dos compatibility flag

D delete a partition

G create a new empty GPT partition table

G create an IRIX (SGI) partition table

L list known partition types

M print this menu

N add a new partition

O create a new empty DOS partition table

P print the partition table

Q quit without saving changes

S create a new empty Sun disklabel

T change a partition's system id

U change display/entry units

V verify the partition table

W write table to disk and exit

X extra functionality (experts only)

Command (enter m for help): n

Partition type:

E extended

Select (default p):

Using default response p

Partition number (1-4, default 1):

3. Check the disk status after partition

5. Mount / dev/vdb1 to / data

/] # mount / dev/vdb1 / data

] # df-h

6. Set up automatic mount on boot.

] # blkid / dev/vdb1

/ dev/vdb1: UUID= "bc972244-2f68-4ba9-af62-6f257c8d2d4a" TYPE= "ext4"

] # vi / etc/fstab (description: edit the file / etc/fstab and insert the line "UUID=bc972244-2f68-4ba9-af62-6f257c8d2d4a / data ext4 defaults 00" at the end of the file)

7. Restart to check whether the auto mount is successful

] # reboot
