February 13, 20251 yr Hi all, I am running an Unraid 7 setup on a Dell Optiplex with a 1 TB SSD in my array. I do not have any parity drives and have a couple of Docker containers up and running. I have installed a 12 TB HDD which is currently being precleared. I want to assign/mount my HDD as Disk 1 in the array (where my SSD is currently assigned to) and to assign the SSD to a new Cache pool. What is the best way to do this? My thoughts are that once the HDD has finished preclearing, to: 1. Stop the array 2. Use the New Config tool to clear the previous disk assigns 3. Assign the HDD as Disk 1 of the array and assign the SSD in the new Cache disk pool. 4. Start up the array and use the Unbalance plugin to move the longer term data storage shares to the array / Disk 1. 5. Finish Will the above approach work? Alternatively, I was thinking that after the HDD finishes preclearing, I could: 1. Stop the array 2. Assign the HDD as Disk 2 of the array. 3. Start the array. 4. Use the Unbalance plugin to move the relevant files / shares from the SSD to the HDD. 5. Stop the array. 6. Run New Config tool refresh the disk mountings. 7. Reassign the HDD to disk 1 of the array and assign the SDD to a new cache pool. 8. Restart the array. 9. Finish Clearly the alternative approach is more complicated, but I just want to know the way to do this without upsetting my current docker containers and settings. Thanks for taking time to look at this and I would be very grateful for your inputs on whether the above works!

February 13, 20251 yr Author Thanks so much for the response, @JorgeB. If I understand correctly, the first approach in which I directly assign the new HDD at Disk 1 of the array and move the existing SSD (that was previously Disk 1 of the array) to the Cache pool seems to be the most straight forward route. The only issue would be since the SDD with the data is now in the cache pool, the unbalance plugin may not be able to move the data out of the cache pool. If so, I could then use the mover script (or the mover tuning plugin) to move the shares / data from the cache pool SSD into the new HDD in the array.
