I had an issue with docker running on a raspberry pi 4 and I purged all of it apart from the folder with the containers/images. Reinstalled docker, run helloworld, runs ok. Installed portainer to manage the containers, several of them start but a particular one, homeassistant, doesn't
It reports
pi@raspberrypi:~ $ docker start homeassistant
Error response from daemon: error creating overlay mount to /var/lib/docker/overlay2/7c4732337e167e0f8178b8667bddc0393c2c1e4f7ffba5d68fe57379cc1de7c0/merged: no such file or directory

Here are the contents of the overlay folder

I've checked the overlay2 folder and indeed there's no merged folder. I've tried creating an empty one, but it gets deleted as soon as I attempt starting the container. What does this folder indicate when it comes to the container and how do I work around it? Ideally I would like to keep the container as otherwise I would have to set up the whole thing again.
