After Updating the OMV OS BOOT Disk is FULL

I have used OMV 5 for a while - Seems that every time I update something happens

I have Updated everything that came up in the list but after I saw that the SSD which has the OS OMV 5 on it is now full. I dont want to play around or start tinkering until I've found out why this has happened. Please could someone help me out with what this could be and how to fix it without losing any of my data?

I use the server for all my Media and Docker. The only program that isnt on the Docker is Plex Media Server which is on a stand alone Windows 10 mini server which I have mapped to run with the OMV server

Im thinking it maybe the updates made by OMV and that the old versions are still on the drive but this would mean over 100GB data has been stored for no reason

Many thanks

Please see the attached screenshot

I have followed that and have it in terminal mac - Honestly dont know what Im looking for. Ill put up in here for u to see

I have a huge Plex Lib but thought using a separate server with Plex Media Server on it that that data wud be stored there?

How wud I find out the docker info? Through root?

```

root@OMV5-Daniel:~# docker info | grep Root

Docker Root Dir: /var/lib/docker```

I have PMS on a separate server but run docker and store all the Media on the OMV server

I cd into /var and did the du command and terminal just scrolled and ran for about 30s but looked like docker overlays were the main thing scrolling. Mainly ./lib/docker/overlay2/ files. I've tried to add all the files terminal spat out in a TextEdit file but its way to big to upload here

Any idea how to firstly stop this happening anymore & then removing these files from the Boot Drive in OMV

Well the problem I have now is I cant log into OMV. I put in my details and it just cycles round to the login page. I think its time for a check of my backups and change OS

Im new to all of this and this is why Im asking in the forum and not trying to do it myself and make more mistakes. I will look into what is wrong today as I have no distractions (KIDS) and hopefully I can find the cause and resolve it

Thanks for the help & apologises for the stupidity

I have done this which I dont know if its correct but Im sure someone will tell me

So what I can see is that its a problem in the Docker folder & that there are loads of 432Mb files in there

KM0201 I found this quote you wrote for someone in July '19 for a similar question with Docker filling up - will this work for me?

1. Create your container folder ("Containers") in the webUI. This will store your containers on one of your data drives (which are presumably much larger than 8gig)

2. SSH your server and get root access

3. Stop docker service: systemctl stop docker

4. Move the docker folder to Containers folder: mv /var/lib/docker /sharedfolders/Containers

5. Create a link between the two: ln -s /sharedfolders/Containers /var/lib/docker

6. Start docker service: systemctl start docker

Problem solved.
