Posted September 18, 20213 yr I am running unRAID 6.7.2 and my Parity disk generates thousands of read errors when the parity check runs. It looks as though I need to do something like the Parity.Swap procedure, but I am not replacing a Data drive as well, and that procedure seems more than I actually need. Is there a write-up which just covers replacing a faulty Parity drive with a new larger unit?
September 18, 20213 yr Community Expert Just stop the array; assign the replacement drive; and then start the array to commit the new assignment and begin rebuilding parity on the new drive.
September 18, 20213 yr Author Can I just clarify what you are saying. At this point I don't need to remove any disks. I simply do this all through the software: Stop the array, un-assign the old Parity, assign the new drive, in its current slot, as the new Parity drive and just start the array. Presumably, after the re-build, I can stop the array, remove the old parity disk and replace it with a new data drive? Thanks

That is assuming the drive you now want to use for parity is already plugged in and sitting in the Unassigned section. When you remove the old parity drive is up to you - it can be done at any time.
September 18, 20213 yr Author Thank you for the advice - I always feel more confident if I have every step spelt out!

If you think the online documentation covering this could have been clearer, then please feel free to mention in what way as it would then be edited appropriately to help in the future.
September 18, 20213 yr Author Unfortunately it doesn't seem to be working. unRAID offers me the new disk to re-assign as the parity, but it then tells me it is wrong to try to do that.
September 18, 20213 yr Start the array with the parity slot blank, then it should allow the new assignment.
