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.
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).
Maybe. Your final step was to insert a new blank disk, which is not part of the array, and that needs to have the OS installed.
Your original array seems to have a failed disk (#3). Let's cross that bridge after getting the system back up.
Thanks for the replies. I've made some progress but now need further guidance.
I have two known good spare unused drives. I tried the OS reinstall on the first one (the same one I used in the earlier test) and it failed with the "ERR: Bad Firmwar" error. I powered it down and tried a second time, using my other good spare disk in bay#1 (replaced the first one). This time it worked, and I can now access the RAIDar interface using the default login credentials. [When I did this, I got a message that there's a newer firmware version available and directing me to install this, but I have not yet done so].
What are my next steps toward the goal of recovering functionality and data?
