October 6, 20232 yr Hi forum, I've got two 4Tb parity drives, that I want to replace with 20Tb drives. Nothing is broken, just planning to start buying 20Tb in the future so planning ahead. I just did : - Stop the array - Remove parity 2 (4 Tb) - Start the array - Stop the array - Added the new drive as parity 2 (20 Tb) - Start the array That's now rebuilding, ETA is 5 days with my services running (ouch). In 5 days, I'll want to do the same with parity 1, but thinking about it now I'm not sure you can have parity 2 filled with parity 1 empty. What would be my best bet ? I believe a "parity swap" procedure would keep the array offline for days, so that's out of the question. Should I have removed both parity drives now and rebuilt 1 instead of 2, leaving 2 out ? Thanks

October 6, 20232 yr Author Oh perfect, then I can just do the exact same procedure I just did but with parity 1 instead. Thank you very much !
