Hi Timiu;

Thanks for your comment. `data-root` option still works. I use docker 20.10.6 and I could manage to move the data folder by that. I've applied the following steps:

* I've created a folder with a privilege that daemon user can access

* Updated /etc/docker/daemon.json as below:

```

{

//...

"data-root": "/mnt/docker-data"

}

```

* restarted docker service.

```

sudo service docker restart

```

And this is how it looks like after I pulled an image from the hub:

```

$ docker inspect alpine|grep docker-data

"MergedDir": "/mnt/docker-data/overlay2/b406450c35da527cf2940b448588ee5c6b83b7b29a7ca820b67934f3e0412fe1/merged",

"UpperDir": "/mnt/docker-data/overlay2/b406450c35da527cf2940b448588ee5c6b83b7b29a7ca820b67934f3e0412fe1/diff",

"WorkDir": "/mnt/docker-data/overlay2/b406450c35da527cf2940b448588ee5c6b83b7b29a7ca820b67934f3e0412fe1/work"

```
