I'm new to unraid. I have five disks in my array and twon ssd's. One of them is an nvme, and the other is a ssd. When i started my array for the first time, I mistakly made both into a cache pool insted of having one a plex mete data drive ,and the other a regular cache drive. Is there a way to seperate the two drives so i can have one cache drive and one drive in unassigned devices to use to transfer data to and from my other server?
