That's OK. I know it was a lot of time between posts and I didn't really explain why we were doing some things. And you ran mover again so system is all on cache now.
Looks good! Go ahead and start dockers again.
Cache has plenty of capacity as long as you don't tell it to keep certain shares there forever. appdata,domains,system are the shares you want to stay on cache (cache-prefer or cache-only). Other shares should be written to the array (cache-no) or written to cache and moved to the array (cache-yes). After you get more experience you can decide if it makes sense to keep other shares on cache. I personally put DVR there for performance, and any recording I want to keep I move to another share on the array.
