Replaced failing disk in NV+ v2 - both volume expansion and volume scan fail

Hi folks, I'm getting some slightly peculiar behaviour from my NV+ v2, and would really appreciate some help in troubleshooting. A week or so ago, I started getting errors on disk 1 of my NAS...

I think you mean TB. With 2x2TB+2x1TB, the system first creates a 3 TB volume, and then immediately expands it to 4 TB. It's not completely clear if the 8 TiB growth limit starts from 3 TB or 4 TB in your case. But either way, you haven't reached the 8 TiB threshold yet (assuming you are correct on the starting point). With 2x3TB+2x4TB you should be at 10 TB, which is only 6 (or 7) TB of growth.

So either something else is wrong, or you didn't have all four disks in place when you did the factory install.

FWIW, what you are attempting has some risk, and you could lose your data.

  That's good news, but wait for the prompt to come back before you reboot.

    Using the "&" backgrounds the process, so you'll get the prompt back right away (the reason I did that is so I could drop that particular shell login and have the process run to completion).
    
    To check that the resize has completed before you reboot, run "top" or "ps -x" and ensure that resize2fs no longer appears in the process list.
