I would like to use my cache drive for my dockers and vms. I'm noticing that my appdata share is showing the array size, even thought it's set to cache only.

My docker volumes are all mapped to /mnt/cache, i'm not sure what i'm missing, is there a symlink? If i make a new container using /mnt/cache, it also comes up in /mnt/user. 

I followed these steps and moved everything from the array to the cache, but it still seems to want to use the array. Also, it didnt delete the appdata files from /mnt/user which im not sure is expected or now.

no longer need to keep diagnostic report up

Because appdata also exists on disk3.  Set the secondary storage to be array with mover action of array --> cache, stop the docker service in Settings -> docker and run mover.

/mnt/user is a unified view of all the shares.  Every share exists within there, along with /mnt/diskX (or /mnt/cache)

Thanks. I just did this but i still see directories that are on disk3

So I tried moving the files from one docker in disk3 into cache, that broke the container a little bit. 

Then I tried mv /mnt/disk3/appdata appdata_bu and everything is running fine now and the cache share is showing the correct size and pool.
