How To Mount Disk In Centos 7

How To Articles

Mounting disks in CentOS 7 is an essential skill for any Linux user. It allows us to access and use additional storage devices efficiently. In this article, I will guide you through the process of mounting a disk in CentOS 7, providing personal insights and detailed steps along the way.

Understanding Disk Mounting

Before we dive into the steps, let’s take a moment to understand the concept of disk mounting. When we mount a disk, we are essentially making it accessible to the file system of our operating system. This enables us to read from and write to the disk, just like any other storage device.

In CentOS 7, disks are typically mounted under the /mnt or /media directories. These directories serve as the mount points for the disks. It’s important to choose an appropriate mount point that reflects the purpose or content of the disk.

Identifying the Disk

The first step in mounting a disk is to identify the device name assigned to it by the operating system. To do this, we can use the lsblk command. Open up a terminal and type the following:

$ lsblk

This command will list all the disks connected to your system. Look for the disk you want to mount and take note of its device name. It will typically be in the format of /dev/sdX, where X represents a specific letter assigned to the disk.

Creating a Mount Point

Once we have identified the disk, we need to create a mount point directory. This directory will serve as the entry point for accessing the disk’s contents. To create a mount point, we can use the mkdir command. Here’s an example:

$ sudo mkdir /mnt/mydisk

In the above command, we are creating a mount point directory called “mydisk” under the /mnt directory. Feel free to choose a different name or location based on your preferences.

Mounting the Disk

Now that we have a mount point, we can proceed with mounting the disk. To mount the disk, we’ll use the mount command. Here’s the general syntax:

$ sudo mount /dev/sdX /mnt/mydisk

Replace /dev/sdX with the actual device name of your disk and /mnt/mydisk with the path to your mount point directory. Once you execute the command, the disk will be mounted, and you can start accessing its contents.

Automounting on Boot

If you want the disk to be automatically mounted every time the system boots up, you can add an entry to the /etc/fstab file. This file contains information about the disks and file systems that should be automatically mounted during the boot process.

To add an entry, open the /etc/fstab file using a text editor such as vi or nano. Add a new line at the end of the file with the following format:

/dev/sdX /mnt/mydisk ext4 defaults 0 0

Replace /dev/sdX and /mnt/mydisk with the appropriate device name and mount point. The ext4 value represents the file system type, which you should replace if using a different file system.


Mounting disks in CentOS 7 is a crucial skill for managing storage devices efficiently. By following the steps outlined in this article, you can successfully mount a disk and access its contents in a personalized and detailed manner. Remember to choose appropriate mount points and consider automounting for convenience. Happy disk mounting!
