unRAID 6.4.0 w/ 2 parity drives   One of my parity drives is failing (Reallocated sector count = 12 and growing). How do I safely remove the failing parity drive? If it matters, I first created the array with a single parity drive and latter added a second parity drive. The first/original parity drive is failing. Drive is under warranty and I have an RMA ready to go.   TIA,   Mike
