Configure new disks I use the fdisk tool to complete these configurations.

I have added a hard drive with 20GB capacity and mounted it to the / data partition.

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

The command # fdisk-l lists the current partition and configuration.

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

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 command commonly used in fdisk / dev/xvdc 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 new partition on Linux

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

Create a primary partition

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

Assign a partition number

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.

Assign sectors to a 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.

Assign partition size

Save your changes and exit.

Save partition changes

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 adds an entry in the / etc/fstab file for automatic mount on permanent startup.

/ dev/xvdc1 / data ext4 defaults 00 Thank you for reading this article carefully. I hope the article "how to add a new hard disk in Linux system" shared by the editor will be helpful to you.
