February 12, 20224 yr I need to replace my parity drive. It's a single parity. Which method is recommended? The new drive is in the server as an unassigned drive at the moment. 1. Unassign current parity drive and and then assign the new drive, letting Unraid rebuild parity 2. Add new parity drive as Parity 2, once parity is rebuilt, remove and forget Parity drive 1 3. Is there another recommended method? I prefer the 2nd option but I have only seen references to forgetting Parity 2 when in dual parity mode. Is it right to assume you can forget Parity 1 just as easily?

Note that Parity2 calculations is different from Parity1 : they are more CPU intensive, but unless you are using a very limited CPU, you should be OK they consider the data disks position in the Array, so you cannot do a new config to move things around and consider that Parity is valid. If those two points are not an issue for you, you can use method 2.
