Cache is always at 100%

[Philippe Bourdon]

Currently running UNRAID 6.2.10 but this has been happening every since I extended my volume from 2 to 4TB on my nvme drive. So, I know my cache drive is 4TB and I also know I use about 35% of that. but it shows 100% used. Sometimes, for not particular reason, it will go back down to 35% which is the accurate dpeiction what what I am using. But if I reboot, it goes back to 100% - Is this a bug? Do I need to worry about this or is it just bad reporting? It's an xfs filesystem.

Thank you and attached.philflix-diagnostics-20240809-1631.zip

 

To be clear, I moved appdata temporaily off the cache drive to see if that would make a difference...

Use the mover and nothing changed.

I think I made a mistake - my cache is 2TB and I guess I oringally had a 1TB volume which I expended to 2TB

Filesystem      Size  Used Avail Use% Mounted on
/dev/nvme1n1p1  1.9T  1.8T   20G  99% /mnt/cache

 

Pool is currently 2T, and it is full

So you are correct... I had to do some digging because I knew that my current environment only utilized 1.2TB.
It turns out, I had a number of local volumes that were no longer being used - and filled up almost 700Gb of my docker.image file.
I ran 'docker volume ls' and the dug into each of them to make sure I could remove them. After I removed them, my docker.image.file shrunk to 1.2TB.

Tnanks for the help.
