lifesupp on Netgear ReadyNAS NV+ v2
It finally happened - I have the dreaded lifesupp message. I've powered down the unit to hopefully preserve whats there. 3 x 5TB Seagate drives XRAID2 (RAID5), started to get warning messages ab...

I have a suspicion 2 out of the 3 drives have failed so i'm not holding out much hope.
Try connecting them to a Windows PC (either sata or usb) and testing them with Seatools (using the long test). Label them by slot as you remove them from the NAS.

Would 3rd party RAID recovery software work? Something like R-Studio. Or could Netgear Tech help to confirm if this is something recoverable? It's a very old unit so well outside of any warranty or support period.
- Netgear does offer a data recovery service: https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service
- R-studio is an option.
- If the disks are reasonably intact, you could try cloning them.
Though you haven't asked, it's best to get NAS-purposed replacement drives (in particular, don't get Seagate DM drives). 5 TB isn't popular now, so you'd need to move up to 6. In this size range, Ironwolf drives are a better choice than the WD EFAX drives.

Thanks - running 'Long Generic' test on the first drive now. Might take a while!

Disk 1 (Bay 2)
Short test: Pass
Long Test: Fail after 10 minutes (Code F167CCDB)
Disk 2 (Bay 3)
Short test: Pass
Long Test: Pass (10 hours)
Disk 3 (Bay 4)
Short test: Pass
Long Test: Pass (10 hours)
So i'm hopeful that I can still recover the data from the 2 working drives, but why would the NAS suddenly not be able to mount the volumes?
If i try any sort of error correction to recover bad sectors on disk 1, will that risk further data loss?
If i go ahead with R-Studio, should I mount all three disks into a virtual raid, or just the 2 functioning disks?
The errors on NAS boot are as follows:
_________________________________________________________________
***** File system check performed at Tue May 26 10:25:31 GMT 2020 *****
fsck from util-linux-ng 2.17.2
fsck.ext4: No such file or directory while trying to open /dev/c/c
Possibly non-existent device?The paths for the shares listed below could not be found. Â Typically, this occurs when the ReadyNAS is unable to access the data volume.

You could try rebooting it with the failed disk removed, and see if that works. Use the boot menu to skip the volume check (pages 24-25): http://www.downloads.netgear.com/files/GDC/RND2110/ReadyNAS_Duov2_NV+v2_HW_en_23-Mar-12.pdf
Or just go right to R-studio. I'd start with just the two functioning disks.

Likely it would, and if the two remaining disks are healthy I think you are better off just using those two.
I've kicked off R-Studio with the autodetection of the RAID parameters, as expected it's taking a while - 1 hour and still no viable configurations.
I dont suppose you know what they would be for a 3-disk XRAID2 do you?
