OMV drive keeps filling up

  • Hi Everyone,

    This forum and community have always been really helpful, so thanks so much for the help to date.

    Here's my current problem: My BananaPi OMV drive keeps filling up. Other posts have said that this has to do with improperly configured docker containers and that may be the case. I'm hoping someone could steer me in the right direction:

  • Thanks! I'm running Transmission and Medusa. Any clue how to delete those files or modify how the containers store them?

    It just isn't possible to provide meaningful help when you haven't posted your current container configurations.

  • It would be better if you could take what is in that screenshot and convert it into a dicker run or dicker create command and post that. Wherever you got the docker image should have a sample file you can look at and correct to agree with your specific use case.

  • Okay thanks everyone for the help. I ended up having some time to mess with the system today and I discovered the following with the following command:

    root@bananapipro:/var# sudo du -sh /var/lib/docker/overlay2

    11G /var/lib/docker/overlay2

    When I give an 'ls' command in that folder just a bunch of numbers and letters fill the screen.

    So that's the folder that is filling up.

    Could anyone tell me what that folder holds, what can I delete and how to keep it from filling up in the future?

  • You need to move your docker folder from the default location at



    /srv/dev-disk-by-<id of your storage disk> /docker

    Then you'd need to go into OMV-Extras->Docker->Docker Storage and enter the new path. If you want to save your old docker contents, you're going to need to ssh into your system and copy it to your storage drive using the bash shell, something like this

    $ sudo cp -Rf /var/lib/docker /srv/dev-disk-<id of your storage disk>/docker

    I just had the same problem, the above is what I did to fix it and it works fine.

  • Fantastic. Thanks for the help.
