For testing, you can always just connect a USB stick, and use that for
the cache.  I've done this on large ZFS systems (24-drives) and on my
home server (5-drives).  Works nicely.

That should narrow it down to either "can't use cache/log on same
device" or "can't use cache and log at the same time".
