@trurl understood, sorry I was only able to post once yesterday so I figured I'd edit and check back in today, thank you very much for catching it and responding anyhow. So it's not helpful in terms of understand what had happened, because after setting the Archive share to 'Cache primary, Array secondary' the mover managed to take everything off the cache and move it back to the array. Then I switched the share back to Array only, and then continued with the rsync. Since then, the items are copying directly to the array and bypassing the cache. So I'm really unsure what happened. It was the first thing I did as soon as I started the system though, so is it possible that it used cache while the Parity was being initialized? Screenshot:
