Why are my "arr" apps using my cache drive?

Featured Replies

* I have had my system for 20 years, so I may have some hidden configuration files I've forgotten about.

* My "Television" and "Movie" shares have ALWAYS used a cache drive.
* I have recently turned off cache for these shares.

* Radarr/Sonarr/Maybe Sabnzbd is writing to /mnt/user/cache/Movies and /mnt/user/cache/Television

This ends up filling my cache drive, because the mover wont move, if the shares are not set to use cache.

I'm really confused why data is going to my cache drive... Any help or direction would be greatly appreciated.

You need to change the paths in the docker arrs containers.

 

If you want a complete guide on how to set up arrs perfectly then there are the Thrash guides at:

Change them to what? They work exactly like I want, until I turn off cache for those shares.

I actually think i misunderstood what you wrote.

You disabled cache for the shares but still want mover to move what the docker containers write?

I disabled the cache for those shares, but somehow Television/Movie files keep getting written to the cache drive.

Okay.

Looking at the picture you have set the arrs to bind to /mnt/user, this should be /mnt/user/Movies and Television.

I don't know what difference it would make - For example, in Radarr, I just have my Library set to /data/Movies

Why have you turned off cache for those shares?

 

I suspect you are falling foul of the behaviour described in the Caution in this section of the online documentation accessible via the ‘Manual’ link at the bottom of the GUI or the DOCS link at the top of each forum page.

Ah ha! It could be that. If I understand correctly... Sabnzbd is downloading to the cache and effectively renaming files and they're staying on the cache drive.


I turned cache off, because I'm upgrading a lot of my files, and going through tdarr. My internet speed is dramatically faster than it used to be, so it's pretty easy to fill up my current cache 3-4 times a day

Turn the cache back on, but make sure you set a value for the Minimum Free Space setting for the pool to stop it filling up too far.  If in doubt as to a good value probably better to err on the side of caution.   When the free space falls below that value then Unraid will start by-passing the pool and writing new files directly to the array.  That way you will get the benefit of using the cache pool when there is space, but things will not stop working when it starts filling up.

Roger. I did not have min free space set for either of these shares.

Here is where I am now.

Note that I said the Minimum Free Space for the pool - not the shares.   The one for the shares is aimed at stopping you filling up array drives too far.  You need to click on the pool on the Main tab to get to that setting for the pool.

Ahhh OK I found it. Looks like I need to stop the Array for that, so I will do it later, but everything makes sense now. Thank you!
