I just can't create and run new containers in Docker anymore. But in the same time a can run previously created containers.

Accepted Answer

The following is for a Fedora/RHEL system, so you'll need to adjust for Debian...

```
# systemctl stop docker.service
# thin_check /var/lib/docker/devicemapper/devicemapper/metadata
```

If there were no errors then proceed with:

```
# thin_check --clear-needs-check-flag /var/lib/docker/devicemapper/devicemapper/metadata
# systemctl start docker.service
# docker run --name=fpm-5.3 debian:jessie
```

To install `thin_check` command, run:

```
# apt-get install -y thin-provisioning-tools
```
