Same on all disk slots That's not how parity swap works, it only works when you have a disable data disk. And that still doesn't answer what happened to disk6, if parity was valid with it it's not without it. Quote Link to comment

After a few reboots the disk was showing as unassigned. Disk was showing errors before Quote Link to comment

JorgeB Posted October 12, 2020 Share Posted October 12, 2020 Just now, xxbigfootxx said: Yes it was Without a disable disk there's no real need to use the parity swap procedure, but it can still be used if you disable the data disk first, like mentioned here: https://wiki.unraid.net/The_parity_swap_procedure Quote Link to comment

Add the old drive back in, wait for the data rebuild then action the steps in the link to stop array, unassign the disk, restart array, stop again, assign new 8tb disk as parity and the 6tb as same data drive that was rebuilt? Would that be the best way to do it? Or is there an easier/faster method? Quote Link to comment

xxbigfootxx Posted October 12, 2020 Share Posted October 12, 2020 Would this be the correct process for that? 1. Remove the 6tb parity. 2a. Add the 8tb as a parity drive. Allow the array to rebuild. 2b. Start the array Allow the array to rebuild. 3. Pre clear the 6th (old parity) 4a. Stop the array 4b. Add the 6tb (old parity) to the array. 4c. Start the array Quote Link to comment
JorgeB Posted October 12, 2020 Share Posted October 12, 2020 Are you going to replace an existing disk with the 6TB or add it as a new disk? If it's to replace an existing disk no need to preclear, even as a new disk Unraid can now clear it in the background, but you can use preclear. Quote Link to comment

Just add it back in as a new disk. I've started the parity sync/ data rebuild, so will hopefully have good news tomorrow when it's completed. Thanks for all your help @JorgeB! Quote Link to comment
xxbigfootxx Posted October 14, 2020 Share Posted October 14, 2020 All finished and parity is valid. Everything working great. Thanks again! 1 Quote Link to comment
