novice ReadyNAS user: "volume expansion failed", how to address this problem?
Hi all, I'm very much a novice when it comes to this machine (I just have put in drives and used it) and I'm having a problem, really hope someone can help. I've just added a WD 6TB drive to my l...

There is no technical reason why the 6 TB drive won't work - Netgear essentially never updates the HCL for end-of-life NAS. There is at least one other v2 user who reported here that he success with this drive.
As far as XRAID expansion goes, on the v2 it does support mismatched drive sizes. The original 3 TB + 2x4TB configuration would not have wasted any space. Adding a 6 TB drive to the mix will result in 2 TB of wasted space, but it should have expanded from 7 TB to 11 TB (10 TiB would be shown on the dashboard).
What volume size are you seeing?

Hi StephenB, thanks also for the help!
That's very helpful info (and I suspected as such, given that specs are often set long before new tech, like 6TB drives, exist).
The volume size I'm seeing now is 6.3TB (the 6TB drive is in, but of course not being used).
I have an 8TB drive coming in (it was going to be an archive drive). With it, I can offload all of the data on my ReadyNAS to start from scratch. Is there a way I can use all the 4 drives I have (3TB, 2 x 4TB and 6TB), avoid any wasted space and keep redundancy? If the 2TB of wasted space is inevitable, I'll just get a 4TB drive instead.
Cheers!
Chas
