August 17, 20223 yr Hello, I am running Unraid 6.10.3. I had a single 800gb ssd as my cache drive which stored my VM's. I added another 2tb ssd and added as a 2nd drive in my pool. So i ended up having a pool of 2 devices. That was the mistake. I wanted to create a 2nd pool in order to have both my ssd's to be separate pools. Now there is a btrfs operation running and i cannot stop the array to fix my mistake. How should i proceed so that i dont lose the data on my original pool cache ssd? Since both ssd's in the single pool right now are of different size what type of RAID is setup automatically?
