I had a similar use case and managed to get everything working with a bit of extra research. I started with just an NVME hard drive, everything was running on this for a couple of weeks while I waited for hard drives to show up. I then added a new hard drive, and added it to the array. My array at the time had zero parity, no cache, 1 NVME, and 1 HDD I roughly followed this video for the next steps but I'll explain below: Install the "Fix Common Problems" app. Then go to Tools -> Docker Safe New Perms. Check, yes I want to do this. and then hit apply. Install the "Unbalance" app. Open it from Plugins -> click on the unbalance icon -> enable unbalance server -> open web UI Select my NVME drive as "from", and the new HDD as the "to" Hit "Plan". there should be no errors because we did the fix common problems step. Hit "Move". After this, all the data should be on the new HDD. Stop the array Go to Tools -> New Config -> Apply Go to Main and put your drives where you want them (In my case, I set the NVME as a cache drive, and the HDD as the single Array device. Start up the array At this point everything was working as I expected.
