I have a 4 node Storage Spaces Direct Cluster. Each node has 4 x 2TB HDD and 2 x 240 SSD.
Recently each node was upgraded to 2 x 800GB NVMe, 2 x 240GB & 8 x 2TB HDD.
The NVMe drives seem to be functioning correctly as cache now as shown below.

What I'm trying to work out before I expand my volumes to use up the new space is how can I set or pin a volume so it is using only SSD for capacity?
