September 1, 20223 yr I recently bought two new drives: 8 TB Western Digital Red 8 TB Seagate Iron Wolf After stopping the array adding new WD drive to parity slot and Seagate to disk 2. It wont let me start the array it says "Stopped. Invalid expansion." I only had 1 x 8TB Seagate Iron Wolf Pro in disk 1 and a 500GB SSD for cache. Any help would be much appreciated!

September 1, 20223 yr Community Expert Solution Try adding only disk2, starting the array, formatting the drive, stopping again, then adding the parity drive as a 2nd step. Edited September 1, 20223 yr by Kilrah
