How to fix the Docker error creating overlay mount?

While running a Docker container, we may sometimes see the below error:

Some of the reasons behind this error are as follows:

1. Filesystem folder for the container is missing.

2. Merged folder for the container is missing.

3. A damaged disc that makes the filesystem corrupt.

4. Editing the files without using Docker.

5. Interrupted I/O operations within Docker.

Methods to fix the error

Method 1

Using

xfs_infoCopy Code

, look into the

/var/lib/docker/overlay2Copy Code

directory and confirm whether or not it can support overlay2. Result

ftype=1Copy Code

shows it can be supported by the overlay2.

Method 2

The below steps can fix the error if the root space is filled.

1. Free up/clear the root space.
2. Restore the Docker folder.
3. Pull the Docker image again.
4. Keep it in the backup folder.

Method 3

Sometimes, we can fix it by changing the disk volume type used by docker into Ext4 or changing the path into an Ext4 volume by this command in

docker.serviceCopy Code

.

ExecStart=/usr/bin/dockerd --graph /new-path/docker

Method 4

The Docker error creating overlay mount appears when the daemon.json doesn’t exist. In that case, we need to create it by editing the text editor under “Configure the Docker daemon by typing a JSON Docker daemon configuration file” >> “Apply & Restart” by opening “Docker Desktop” >> “Preferences” >> “Docker Engine”.

Method 5

For Mac, we can resolve this by doing a factory reset in Docker.
