Can no longer install anymore docker containers as it states that there is no space. I check via terminal and using mc to navigate and when I enter the /mnt/user/ directory I see 3631G/3948G although the Dashboard shows 273GB used and 3.73TB available and I know for a fact that I do not have near 4TB of data on my array.

 

Can anyone help?

 

I have dug around but not much stands out as to why I am getting this error. I have 50GB allocated for the Docker image and only 12GB is used. My SSD cache pool has plenty of space.

 

When anything is written to /mnt/user/ is it suppose to then offload somewhere? All that I add to the array can be seen in /mnt/user. Perhaps my Shares are set up incorrectly? All are marked High-Water. I have noticed a /mnt/user0 folder but not sure what that's about.

You should post your diagnostics

Hopefully this helps? This is the read out I get after "installing" PiHole. Docker container claims to be there but directory does not exist

 

Tools, diagnostics. Attach the zip file you download from there intact to your next post.

Oh thanks @jonathanm attached now

Seems to be any time Unraid wants to write to /mnt/user/appdata it fails stating that there is no space even though its essential to my disk array with almost 3.5TB of space available

I try to terminal in and try to create just a folder to that location and states the same error in terminal too

Please post a screenshot of your Docker tab so we can see all the containers and their volume mappings.

Also have docker update notifications that when I hit update they claim they are updated to the latest 

I noticed this issue with pihole so I changed the directory from /mnt/user to /mnt/cache

Send us a screenshot of your Main tab.  According to your logs, your cache drive is full.  I see numerous of these in the logs:

That means your cache is filling up and has no more space.

The cache drive isn't full.  Your problem is that you've set the minimum free space for the cache drive to be 1TB.  When entering in numbers without a GB, MB (eg) suffix, the value is assumed to be in K.  Fix it in Settings - Global Share Settings

You caught what I missed!  Nice one!
