ReadyNAS NV+ V2 Disk Error, But Not Showing Which Disk?
I have a ReadyNAS NV+ V2 with 2 x 2TB (bay 1 and 2) and 2x 3TB (bay 3 and 4) running the most recent firmware.
It's had a panic attack and 3 disks showed up with a first aid icon, this then boiled itself down to disk 4. I swapped disk 4, for the system to start resync, only for the unit to show lifesupp!
I swapped the old drive back in, and it started to resync again, I could see and access all the files, and was doing well, but again failed.
I assume this is because of bad sectors on other drive/s? The system is reporting healthy on RAIDar, but although I can see the shares, I can't drill down into them. The admin also won't show any system data, only the logs.
The logs are showing that "volume scan failed to run properly" and also that the "all the paths for the shares listed below could not be found", finished with "system is up"...
How do I workout which disks to swap out? Or have I a situation where multiple disks have failed?
Which log file should I look at for more detail to the drive and problem?

I suggest downloading the full log zip.
If you have trouble figuring out what's in there, I'd be willing to take a look. Put the full zip into cloud storage (dropbox, google drive, etc), and send me a download link in a PM (private message). Make sure the link permissions allow anyone with the link to download. You can send a PM using the envelope icon in the upper right of the forum page.
Maybe also power down the NAS and test the disks in a PC with vendor tools. Label them by slot as you remove them.
UPDATE: I pulled the bay 4 disk out and restarted - I can see all the files and folders, but the unit is "unprotected". I've ordered a USB SATA cable to run diagnostics on the failing disks, and the replacement disk which flunked. Hopefully I can bring the whole thing back to life and protected again - and then repurpose.
Thankfully, the ReadyNAS had a single USB drive connected which backed up the whole box - I was able to use this to transfer the files to a 4 bay synology. What I'm doing now is simply checking the USB and the ReadyNAS are sync'd and up-to-date.

I like to run both a full non-destructive test and a full write test. Unfortunately WDC's Dashboard doesn't include a full write/erase test. I think Seatools might let you do it (even with a WDC disk).
On disk options - best to avoid WD Reds, as they are SMR (shingled magnetic recording). Sustained write speeds can be extremely slow. WD Red Plus (and Pro) are CMR (conventional magnetic recording), as are all Seagate Ironwolf drives. Stick with NAS-purposed drives, as most desktop drives in the 2-6 TB size range are SMR (and many shucked USB drives are also).
