Hi!

My free disk space has been slowly getting smaller and smaller. This is not due to the Plex library. My knowledge is somewhat limited, but I saw that the overlay2 map under /var/lib/docker/ has been growing, and is now about 71gb (see screenshot).

Is this normal behaviour? Can I do anything do stop this, or perhaps delete something?

Thank you for your help.

Got the same issue. I switched over to NZBGet and my Overlay2 volume has consumed most of my boot drive now. Not sure why it is doing this.

Well... check this out

Now both "merged" and "Diff" are exactly the same

I always thought that something REALLY goofy is going on with Radarr.

I think I'll be switching over to Couch Potato for the time being... Wow... Never thought it would ever come to that.

Please check here for the fix.

I'm not sure why but some of the movies are getting put into the /opt folder

ROOT CAUSE!

Using IP Addresses in Ombi. When the container gets rebuild, it can get a different IP Address and then weird s*hit happens.
Problem is that Ombi has a lot of issues talking once it is setup. Constant spinning circle of death.


Keep reading... root cause below.

Thanks for all the replies. Now I am not sure if this is Radarr's fault or Ombi. I use both. There are not IP's in Ombi as far I can see, everything is localhost.

I checked some random overlay2 dir's, and they are all around 500 to 700mb and contain merged dir as attached. They are now around 55gb.

Can't I just deleted all these random directories? What could go wrong if I do this?


Edit 1: Could it possibly be backup's created by Plexguide? Because every structure seems the same (see screenshot #2).

Haha, that is good to know. I was just about to delete the whole folder because it is becoming so big.

Does the structure inside these folders reveal what the cause is?

It actually does. Are you using lists in Radarr? THAT was my root cause. For some reason Radarr would default the folder for these lists to the /opt directory and I could not get it to change in the webgui. I have removed all my lists and that fixed it.

Yeah, I use lists but they all point to /unionfs/movies, so that seems correct. Also, no directory in that overlay2 directory is over 800mb, and that is not a movie size I ever download.

Edit: Also, it is not the /opt/ that is getting big, but my /var/ directory.
