tjsyl Posted June 5, 2023 Share Posted June 5, 2023 Found and read a 2020 topic about this but my situation is a bit different so I figured I would start a new topic. 2- 4TB parity drives, 5- 4TB in the array, 2- 8TB in a Mirror for all my Media. I have 4 "new" 8TB drives that I am preclearing on my test UR server at the moment. I am physically moving the drives from a Z820 to an entirely different PC but plan on just moving my flash drive over. I want to replace the parity drives (2x4TB) with 2 8TB drives. After booting up on the new hardware do I need to do both parity drives at the same time or one at a time? After the parity rebuild is done I will transfer the Media data off the Mirror array and rope those 2 8TB drives into the Unraid Array. I am going to add 2 of those 8TB drives to the "in case shit" box with the other spare 4TB spare drives I have. Quote Link to comment
Solution JonathanM Posted June 6, 2023 Solution Share Posted June 6, 2023 You can do the parity drives one at a time to maintain redundancy. 1 Quote Link to comment
tjsyl Posted June 6, 2023 Author Share Posted June 6, 2023 Ty, I guess I knew that. I guess I just want to do both at once to cut down on the rebuild time. Quote Link to comment
