Readynas Ultra 6 Expansion Failed

Hi guys

I have a ReadyNAS Ultra 6, initially with 6x2TB drives (one drive redundancy).
I have replaced 4 of those with 3TB Seagate drives (so now 4x3TB + 2x2TB).

All drives are working fine but when I reboot the unit in order to expand it, I get a Expansion failed error
Under the Volumes tab on Frontview it seems all the space on the new drives has been allocated.

I downloaded the expansion log and it reads as follows (my bol in the "Permission denied" bit).

Any ideas what I could do that does not involve a factory reset? Not sure where I'll plonk 7 TB of data...

    So were all 6x2TB drives installed when you last did a factory reset?

    Hmmm... I can't remember for sure. I think I initially had 4x2TB and then added another 2.

    If you started out with 3 or less 2TB drives it's possible you might be hitting the 8TB online expansion limit where you can only expand the volume online by 8TB over the life of the volume.

    Well, my volume was already 10TB (5x2TB + 2TB for redundancy) so that doesn't seem to be the case...

    I don't think you understood what I was trying to say. The 8TB online expansion limit would mean if your volume started out with a volume capacity of say 4TB then it couldn't expand beyond 12TB.

    Ah, I clearly misunderstood what you meant, sorry...

    I thought the limit was 16TB?

    So this is really going to be a case of factory resetting the unit? What a major PITA, if so...

    That's a separate expansion limit. You can't expand past 16TB you have to factory default with that capacity in place. So even if you factory default with say a volume of 15TB you can't expand past 16TB.

    You could contact NetGear support to see if they can confirm my suspicion that you may be hitting the 8TB online expansion limit. If that is the case then you will need to do a factory reset. You should really backup important data regularly anyway and now would be a good time to start.
