ReadyNAS NV+ Kernal Panic
Trying to determine if it's possible to recover from a Kernal Panic situation on the following unit and, if so, get guidance on how to proceed:
ReadyNAS NV+ [X-RAID]
Firmware: RAIDiator 4.1.14 ...

OK. Can you point me to a link that describes what's involved in that process, and/or how I pursue it?
Netgear's service is here: https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service
Seagate has a service, and they claim support for any NAS. I haven't seen any posts here from people who've used it. But there is information here: https://www.seagate.com/services-software/recover/in-lab-recovery/ Note they don't limit their service to seagate drives.
If you can connect the drives to a Windows PC, then you could use R-Studio or ReclaiMe. Both allow you to see what might be recoverable before you need to pay.

Assuming I accept the data loss, what are my next steps to rebuild the NAS with my 3 existing good disks plus the new blank one? [Recognizing that doing this rebuild will wipe the data from the 3 existing disks].
You do a factory reset with the disks installed. See page 23 here: http://www.downloads.netgear.com/files/GDC/RND2110/Duov1_NV+v1_HW_en_06Dec11.pdf
Alternatively, zero the disks with vendor tools in a Windows PC (lifeguard or seatools), and just power up the NAS with the disks in place. That will do a factory install. Zeroing the disks is a good diagnostic, it can find drive issues that the non-destructive tests miss.
You have removed all critical disks, and installed a new blank. OK, so now you can re-install the default firmware (factory reset) and check that it works?
I believe (*fairly certain*) that the firmware reinstall will have zero impact should you later need to insert your original data disks.
This will at least get as far as checking that the unit is working fine.
Thanks for the reply. Can you point me to a link with instructions for reinstalling the firmware for this unit?

Start with just the OS reinstall: https://kb.netgear.com/24874/How-do-I-access-the-boot-menu-on-my-ReadyNAS-Duo-NV-NV-X6-or-600
OK thanks. Am I correct that I'm dealing with two separate issues - a failed disk (#3), and a corrupted OS? If so, are these related or did I just happen to discover the failed disk as a result of the OS becoming corrupted?

They likely are related.
The OS-reinstall might not help and the factory reset will destroy your data - which of course is something you want to avoid. You might need RAID recovery if the OS reinstall fails (or accept the data loss).
