In share settings I set "Use cache (for new files/directories):" to Yes/Preferred (forgot which one, I keep changing to test them out).
I pressed mover button. It says beside Yes/Preferred "Mover transfers files from array to cache". My cache drive now has files from my array which makes sense.
How do I clear the files from the cache drive or flush the cache drive? It's currently at 100%.
Here's where my VM experience may run out for your purposes. I'll teIl what I have and maybe others will chime in.
Dockers do most of what I need. I only have a couple VMs, that I don't consider critical (yet), just playing around for now. Neither of the VMs need multiple vdisks, or even large ones (32G and 15G). Both use VNC for remote desktop with no dedicated graphics.
I have 2 pools. One, named "fast", is 1x256G nvme formatted XFS, and another, named "cache", is 2x500
