February 14, 20251 yr Hey all, I am looking to add a new largest drive to my server, 16TB, and it has been a while since I have done this so I found the instruction that I should do a Parity Swap to be able to upgrade. Following the Unraid Parity swap instructions, I got through and began the parity copy. However the copy is extremely slow (5MB/s). I really am looking to get my server back up and running ASAP and do not want to have to have the server down for another week while this copies. Notes: I am adding a 16 TB WD drive that I ran through 2 cycles of preclear. I disabled my disk 6 (the drive did not have any errors and is a good disk with the data). a 10 TB WD drive is the drive that it is copying the parity from and is set to replace disk 6. I had 2 disks of parity. My docker services are disabled while I am working on getting my array back up and running. All drives are CMR Hardware: CPU - Dual Intel® Xeon® CPU E5-2620 Mobo - Supermicro X9DR3-F Ram - 32 GB ECC RAM Honestly my preference at this point would be If I can cancel the Parity Swap, re-enable my disk 6 with the data it already had, and replace the Parity drive with the 16TB and let it rebuild parity and add the 10 TB after would be preferred. Any help would be appreciated. tower-diagnostics-20250214-1208.zip

You could do that with New Config
February 15, 20251 yr Author I ended up canceling the Parity Swap, and using New Config to restore the array. Then built it with the new drive and got rid of my existing parity. The array started and now the parity is rebuilding with the new drive.
