ReadyNAS NV+ after HDD upgrade
I decided to upgrade my NV+ V1 with 4.1.16 and X-RAID from qty 4 1TB drives to qty 4 2TB drives yesterday morning. Followed the Netgear recommendation to pull the 1st drive hot and replace it, and AF...
My situation gets worse: I've reverted to the original 4x1TB drives, all of which have worked fine for years and which have good Health/SMART status afaict, and today I got another kernel panic, after it had been working just fine for a couple days (though only a few hours at a time--today is Backups day and so I leave it on all day and make an rsync bu to USB which btw worked fine too, but it paniced mid-afternoon after being on for 8 or 10 hours).
After pulling the plug on the NV+ and re-powering, I ran a Memory Test which came-out OK (I have the stock RAM) and upon Booting it did the expected FS and Quota CHKs, but now the box is doing a Resync, as if I'd pulled or replaced a drive or ??? Says it's gonna take 12 hours to do this.
What to do next? Shut it down and pull each drive one-by-one and test them? Or maybe I should try instead an OS Reinstall in case something got hosed in the config files, maybe when I installed those 2TB drives?
I do have a spare platform I could try, but I'd have to update its firmware first and honestly this doesn't feel like a Sparc or mobo or power supply problem to me.
Here is the dmesg.log which shows a bad block in the NAND? What's that, the onboard firmware? I checked back on ancient (working system) logs and it has always been there so I dunno that could be the problem now?

Yes. The firmware install is stored in the onboard flash (and I believe the boot loader is also). It looks like the system is sparing the bad block, so I agree that doesn't seem to be the main issue.

I'd let the resync continue to completion. This is likely a side-effect of the kernel panic (unclean shutdown).

Ok. So this means the kernel panic isn't linked to the new disks.
I'd suggest backing up the data and trying to do a factory reset with the 4x1TB drives in place. You could do an OS reinstall first I guess, and see if it helps. The OS reinstall doesn't reinstall everything, so it might not help if there's some corruption in the OS partition.
Another option is to do a factory install with one of the 2 TB drives (leaving the other bays empty). Don't use the one that initially failed Seatools, since it's health is unknown. Then add the other disks one of a time, and see if the kernel panic strikes again. If all looks well, then reconfigure the NAS and restore the files from backup.
Though I do think you should consider how much time/energy you want to put into this. It might be time to get a new NAS and let this one go.
All good thoughts, thanks. Now For The Dumb Questions: I've been backing-up the entire volume, the C: drive, using Rsync to an external USB. If I were to do the Factory Reset/Reinstall, how do I recover from this USB backup? And do I restore my CONFIG file using FV Before or After I get the files from USB drive back onto the NAS?
As far as ordering goes, it's best to
- reinstall add-ons
- restore configuration
- restore data
The add-ons are first because some of the configuration files relate to the add-ons.
Frontview won't let you restore the full hardrive in one restore operation (annoying limitation). So you'd need to restore share by share. Do you use the private "home" shares?
You could also run rsync directly from the linux CLI. That would let you restore the full C volume.

Dunno what "private 'home' shares" are? I have Security as User Mode with just 4 users, then 4 shares: backup, downloads, tom, and media. When I look in Windows Network Neighborhood I find a "home" directory at the root level, with 4 subfolders named according to my 4-person user list, and these are all empty. So maybe the answer is No?
If you know the rsync CLI command I do know how to access via SSH and would give that a try first I guess.
Thanks!
