Expanding volume on 626 - Raid 5 to Raid 6 not automatic
A quick note, the RN626X is not listed in the Model drop down when starting a new converstation. So I choose the 716X which is close enough. That said, I recently expanded the volume on my 626 from 4x4TB to 6X4TB. The existing volume was Raid 5, but I was expecting it to automatically migrate over to Raid 6 after adding the 6th drive. However, this did not happen so I'm guessing it requires manual intervention and if true then I fear the existing volume may be destroyed in the process. Can any confirm the process either way?
Before the upgrade:
After the upgrade:
You had to disable X-RAID and choose the next disk added to add parity, add that disk and then you could have re-enabled X-RAID again.
Now all the drive bays are full it's too late to convert the existing volume to RAID-6.

It won't migrate to RAID-6 unless you tell it to. So now destroying the volume would be necessary to switch to RAID-6.

That's a bummer since it would have been nice to know this in advance. I like the idea of having 2 redundant drives but not if I have to destroy the existing volume to achieve it. Although, Raid-5 does provide more volume so I guess that's a positive. Anyhow, what is the process to move from Raid-5 to Raid-6 should I want to do this in the future? I don't see Raid-6 as an option when clicking on X-Raid button. The only option is for Flex-Raid. I suspect a factor reset would get it done and the option for Raid-6 would be present then?
