I'm running Docker version 20.10.5 on a Centos 7 Box. I stopped my project with docker-compose down and every container had the same message -
Error response from daemon: container <container ID>: driver "overlay2" failed to remove root filesystem: unlinkat /var/lib/docker/overlay2/<long number>/merged: device or resource busy
I've stopped the daemon, I've reinstalled Docker, I've tried umount, lsof, kill, and all the docker go-away commands including system prune but still they hang on.
(After re-installing Docker the status changes to Dead. When I try to delete the zombie containers their status changes to Removal In Progress)
How can I get rid of these containers?
