though this is rarely needed.
If the plugin fail to work properly, and only In last resort after you tried diagnosing with the above methods, you can try clearing the state of the plugin. **Note that all exiting rclone docker volume will probably have to be recreated** (This might be needed as a reinstall don't cleanup existing state files to allow for easy restoration, as stated above.)
```
docker plugin disable rclone # disable the plugin to ensure no interference
sudo rm /var/lib/docker-plugins/rclone/cache/docker-plugin.state # removing the plugin state
docker plugin enable rclone # re-enable the plugin afterward
```
## Caveats
Finally I'd like to mention a _caveat with updating volume settings_.
