Hey guys! I can't figure this one out, even though it seems like it should be pretty simple.. I upgraded my parity drive to a larger one and now want to use the old drive in the data array. No matter what I do it stays as unassigned. I've tried deleting the partition and adding it without formatting. Reformatting to xfs, even though the array is xfs encrypted. I've restarted the pc. The only thing I can think of is going into the new config tool but I don't want to mess with that before asking here. Any help is appreciated!

After some more reading, it looks like I might have to go ahead and let the drive preclear to then format it correctly. Why is this? I thought preclear was just a peace of mind testing tool and not a necessary step to even use the drive.

You don't need to preclear, just add it to the array, it will be cleared in the background, when done it needs to be formatted.
