Fix Docker Won’t Start After Path Change

If changing the storage path of Docker causes it to not start, it is usually due to permission issues or errors in the path configuration. Here are some possible solutions:

1. Checking permissions: Make sure the new storage path has the correct read and write permissions. You can use the ls -l command to view the directory permissions and use the chmod command to change them.
2. Check the path configuration: verify in the Docker configuration file (usually located at /etc/docker/daemon.json) that the new storage path has been properly configured. Ensure that the path is correct and there are no spelling errors.
3. Restart Docker service: After changing the storage path, you need to restart the Docker service to apply the changes. You can use the command sudo systemctl restart docker to restart the Docker service.
4. Check the logs: If Docker fails to start, check Docker’s log files for more information. You can use the command journalctl -xe -u docker to view Docker’s system logs.

If the above methods do not solve the problem, further debugging and troubleshooting may be necessary. You can try using Docker’s detailed logging feature to gather more information, or seek advice from others in the official Docker community.
