April 25, 20242 yr Don't ask how I got in this situation 🤦♂️ In my 22 drive array (chassis can handle 24 drives) the largest drives I have are 8TB. I have dual parity. I have two failed drives. I have 4x 10TB replacement drives. I was hoping to rebuild the two failed drives onto 10TB and then swap the dual parity for 10TB but of course unraid won't allow me to install a replacement data drive larger than parity. Is there any way at all to have unraid treat my 10TB replacement drives as 8TB temporarily or will I need to buy some 8TB drives (would really rather not). Any clever ideas?

April 25, 20242 yr Community Expert Solution What you need is the parity swap procedure which is designed for exactly this scenario. It allows you to upgrade a parity drive to a larger one and then use the old parity drive to replace the failed data drive.
