In Linux, mounting devices or filesystems allow users to access external drives, network filesystems, and partitions. However, one common error encountered during this process is the “Mount Point Does Not Exist” error.

This guide will help you understand the causes of this error and provide clear steps to resolve it.

What Is a Mount Point in Linux?

A mount point is a directory in the Linux filesystem where an external device or partition is attached. Once a device is mounted, its contents become accessible via this directory. Common mount points include /mnt, /media, and user-created directories like /mnt/my_mount_point.

Understanding the “Mount Point Does Not Exist” Error

The “Mount Point Does Not Exist” error means the directory where you are trying to mount your filesystem does not exist. This usually happens when you specify a path that is either misspelled or has not been created.

For example, running a command like:

mount /dev/sda1 /mnt/nonexistent_directory

You will see the following error:

mount: /mnt/nonexistent_directory: mount point does not exist.

This error indicates that the directory /mnt/nonexistent_directory doesn’t exist, so the system can’t attach the partition to it.

Let’s explore how to fix this issue step-by-step.

How to Check If a Mount Point Exists

First, check if the directory (mount point) exists. You can do this with the ls or find commands:

Check using ls command.

ls /mnt/my_mount_point

You will see the following output if the directory doesn’t exist.

ls: cannot access '/mnt/my_mount_point': No such file or directory

Check using find command.

find /mnt -type d -name "my_mount_point"

You can not see any output if the directory is not found.

If the directory doesn’t exist, you’ll need to create it.

Creating a Mount Point Directory

To fix this error, you need to create the mount point using the mkdir command. Let’s assume we want to create the directory /mnt/my_mount_point.

Create a new mount point directory.

mkdir /mnt/my_mount_point

Verify the directory was created:

ls /mnt

Output:

my_mount_point

Now that the mount point exists, we can move forward with mounting the filesystem.

Mounting the Filesystem to the New Mount Point

Once the mount point is created, you can proceed with mounting the filesystem or device. Let’s look at a few different examples of mounting filesystems:

Mount a local partition.

mount /dev/sda1 /mnt/my_mount_point

Mount an external USB drive.

mount /dev/sdb1 /mnt/my_mount_point

Mount a network filesystem (NFS).

mount -t nfs server-ip:/path /mnt/my_mount_point

Verify the filesystem is mounted.

df -h | grep my_mount_point

Output:

/dev/sda1        50G   20G   30G  40% /mnt/my_mount_point

Making Mount Points Persistent Across Reboots

By default, when you mount a device or filesystem using the mount command, it will be unmounted after a system reboot. To make the mount point persistent, you must add it to the /etc/fstab file.

1. Edit the /etc/fstab file:

nano /etc/fstab

2. Add an entry for the device:

/dev/sda1 /mnt/my_mount_point ext4 defaults 0 0

3. Save and exit.

4. Test the /etc/fstab entry:

Run the following command to verify that the fstab entry is correct and the filesystem can be mounted automatically:

mount -a

If no errors are returned, the entry is correct, and the device will be mounted automatically after each reboot.

Checking for Mount Point and Filesystem Issues

If you’re still encountering issues with mounting, you can use dmesg or journalctl to check for system logs related to the mounting process:

Using dmesg to check system messages:

dmesg | grep mount

Using journalctl for recent logs:

journalctl -xe | grep mount

If the issue is related to the filesystem (e.g., corrupted files), you can run the fsck (filesystem check) utility to repair the device:

fsck /dev/sda1

Follow the on-screen prompts to repair any issues with the filesystem.

Conclusion

The “Mount Point Does Not Exist” error in Linux can be frustrating, but it’s usually straightforward to fix. By creating the mount point directory, checking for typos, and verifying device connectivity, you can resolve the error and successfully mount your device.
