Dual Redundancy / raid-6 on OS 6

So I have am serveral days into the process of getting a dual redundant OS 6 nas. Really, there has got to be a better way than this; assuming starting with a new clean nas, - update to latest...

I tried to follow this process. Here is my result. My system is OS 6.3.5 beta on Pro 6 with upgraded RAM and processor, 5 x4 TB when fully configured.

- update to latest firmware
- factory default with the number of drives you intend to use, minus 1 (4 drives in my case)

- wait ~16 hours for xraid2/raid5 volume to become redundant
- totally un-intuitively disable x-raid mode (don't panic it can be re-enabled later)
- insert last drive - 30 seconds later it started to rebuild. I could see the "Add Parity" button greyed out and nothing happened when clicked. This Add parity button disappeared once the new disk had completed rebuilding.
The process does not offer to allow me to delete newly created volume

I am left with RAID 5 XRAID -- I am at a loss about how to get to dual parity.

Unfortunately, once the volume has expanded you can't get to dual parity.

  Ouch. That means I need to start again. If I redo the process, it sounds like the instruction to put all the drives into the RNAS and quickly switch to Flex-RAID is the way to go.
