So I added two new SSDs to my cache pool (previosly it was only one SSD) to expand and add redundancy to the pool, but when I tried to format the SSDs to added them, the new SSDs failed. All the SSDs are connected to a 12 port back plane. When I connect one of the new SSDs to the mother board using SATA cable it works and does get formatted correctly but then the second new SSD connected via the backplane fails. The cache pool is zfs pool.
