February 13, 20206 yr I feel like this is answered somewhere but my google-fu is lacking and I can't find the answer. I have 2 , 2TB parity drives in my unraid. Parity1 has started tossing SMART errors so I'm going to replace it. I have a 4TB drive I can replace it with. The process I was going to try is stop the array remove parity1 from the assignments. power off replace parity1 with a 4TB drive power on assign the 4TB drive as parity (at this stage I will have a 2TB and a 4TB parity drive, will that work?) let the parity rebuild eventually replace the other 2TB drive with a 4TB drive. Does that seem sane? Do I need to do anything special for replacing a failed parity drive vs a data drive? Thanks and sincerely sorry if this is answered somewhere already.

February 14, 20206 yr Obviously all your data disks will stay smaller than 2tb until both parities are done as always. Assume you know this. Just saying in case anyone else is reading.
February 14, 20206 yr Author That procedure worked, I'm rebuilding Parity1 now with a 4TB and when that is done and stable I'll swap in another 4TB drive for Parity2. Thanks!
