Have RAID5, 5TB populated out of 10 available: any hope of increasing to RAID6 without reloading?
Somehow I messed up in my RAID level specification.
Now, after two days of loading, my new RN316 with 4-4tb drives has 5 tb of data on it but the RAID level is only 5 and I wanted 6.
Projected capacity at 6 is 7.something tb and only 5 tb is loaded - so it would seem like there might be a glimmer of hope....
I have no probem with buying a couple more 4-tb drives because that's where I am headed anyhow.
The Question:
Is there a way for me to change from RAID5 to RAID6 without having to reload the array?

I cannot find any way to edit my OP, so here goes....
I think I answered my own question and the answer is "No, a RAID5 array cannot be upgraded to RAID6 without wiping the data and then reloading after the upgrade.".
But that begs another question: Do I want RAID6 or X-RAID2?
The desired bottom line is that the box can have two (2) drives fail and still not lose any data.

If you are going to be wiping things out and stating over, you may want to consider moving to OS6 on your Ultra6. It gets rid of a lot of the volume limitations, allows you to move between XRAID and FlexRAID (as long as there is only one data volume), and is based on a current Debian distro.
Don't be confused about the "2" in X-RAID2, it's just the name of the feature as shown on your device. It was called X-RAID on RAIDiator 4.1, then X-RAID2 on RAIDiator 4.2, and X-RAID again on ReadyNAS OS6.
To use RAID6 on your Ultra6, you need to use Flex-RAID (For OS6: disable X-RAID after initial setup, recreate the volume as desired. For RAIDiator 4.2: use RAIDar during initial setup.).
- Thanks for correcting.
