I want to change one harddrive in my RN104. I am running 4x4TB WD red drives and I want to replace one of them with a 2TB version

Unfortunately you can't do that.  XRAID lets you expand using bigger disks, but it doesn't let you contract using smaller ones.

You could either back up the data and do a factory reset with the 2 TB disk in place (restoring the data later); or back up the data, destroy the volume, downgrade the disk, create a new volume, and restore the data.

The NAS isn't using ext4, and even if it were, it would need to reformat the drive.  It's simplest to install a blank (unformatted) drive.  If it is already formatted, you'll need to format it in the NAS before you add it to a volume.
