Linux add hard disk methods: 1, use the fdisk command to display the current hard disk partition, press the "n" key to add a new partition; 2, use the mkfs command to format the partition; 3, use the mount command to mount the partition; 4, use the "defaults 00" statement to set up automatic mount when starting permanently.

The operating environment of this tutorial: linux7.3 system, Dell G3 computer.

How to add hard disk to linux

A hard drive with 20GB capacity has been added and mounted to the / data partition.

Fdisk is a command line tool for displaying and managing hard drives and partitions on Linux systems.

# fdisk-l

This command lists the current partition and configuration.

After adding the hard drive with 20GB capacity, the output of fdisk-l looks like this.

# fdisk-l

View new partition details

The newly added disk is displayed as / dev/xvdc. If we add a physical disk, it will appear similar to / dev/sda based on the disk type. I'm using a virtual disk here.

To partition on a specific hard drive, for example, / dev/xvdc.

# fdisk / dev/xvdc

Commonly used fdisk commands

N-create partition

P-print partition table

D-Delete a partition

Q-exit without saving changes

W-Save changes and exit

Since we are creating a partition here, we will use the n option.

Create a primary partition or an extended partition. By default, we can have up to 4 primary partitions.

Enter the partition number as required. The default value of 1 is recommended.

Enter the size of the first sector. If it is a new disk, usually choose the default value. If you are creating a second partition on the same disk, we need to add 1 to the last sector of the previous partition.

Enter a value for the last sector or partition size. It is generally recommended to enter the size of the partition. Always add a prefix + to prevent the value from going out of range.

Save your changes and exit.

Now use the mkfs command to format the disk.

# mkfs.ext4 / dev/xvdc1

Format the new partition

When the formatting is complete, mount the partition according to the following command.

# mount / dev/xvdc1 / data

Add an entry in the / etc/fstab file to automatically mount on permanent startup.
