The disk that was tossing errors "Raw read error rate" (raw value of 1) is now zero. "Returned to normal". However the Multi zone error rate is still 1. Now my Parity disk has a Raw read error rate of 1, and UDMA CRC error count of 53. So something is up. But I am not sure how to keep chasing this one. I do have 1 8TB drive with less then 48 hours on it so my plan was to put that in the parity slot. Then build parity. Once that was correct I was going to replace all my 4tb with new 8tb disks. I guess my question now is, I can just shut down, remove the parity disk, add the new parity disk, boot up and let it build right?
Looking at this (https://docs.unraid.net/legacy/FAQ/parity-swap-procedure/), I am right. But maybe I am doing it wrong lol
This procedure is strictly for replacing data drives in an Unraid array. If all you want to do is replace your Parity drive with a larger one, then you don't need the Parity Swap procedure. Just remove the old parity drive and add the new one, and start the array. The process of building parity will immediately begin. (If something goes wrong, you still have the old parity drive that you can put back!)
