Ok, so I almost have my N5200Pro working exactly as I want it to, but not quite. I created a 5 disk RAID5 array using all the internal disks, assigning 10% of space for data, the rest for iSCSI. I now have an eSATA caddy that is hooked up, the disk is visible but it seems impossible to make the disk available to use - I cannot expand the RAID to include it, not can I make a second RAID as all 5 internal disks are in use. How can I go about this?
