PR4100 Adding Drives

I setup my PR4100 with a pair of 4TB drives and configured RAID etc All worked ok

I now want to add a pair of 10TB drives to complete the 4 drive stack but when added, the GUI webpage shows the drives in situ but does not appear to show a way to integrate them into the RAID stack

Am I missing something?

@RDF Doesn’t sound like you have a My Cloud Home so you probable want to post your topic here.
