I have 4 x 2TB drives in RAIDZ1, plus a spare, all mounted in a 5-drive cage (5 drives vertically in the space of 4 5.25" drives). I started getting SMART errors on one of the "active" drives (ada2), so I took it offline and replaced it (via the GUI, not physically) by the spare (ada4). Resilvering is still in process. When resilvering is complete, can I move the ada4 drive physically to the ada2 position (so that the replacement spare will still be ada4), or will that confuse FreeNAS?
