Got this message today. Everything was working fine. Where do I even start?

I found this:

but it does not clarify what resolved the issue, reinstalling freenas on the USB or upgrading the ram.

Typically that means the boot device died, so reinstalling on a new stick should resolve it. It never hurts to add more RAM while you're at it :smile:

Do you have a backup of the config db?

I've actually tried reinstalling on the same USB stick, and it will run again; but once I reimport the ZFS array, it fails. The logs show that the system had unauthorized reboots several times. I think perhaps the power going to the server wasn't as reliable as I thought. I have since bought a UPS, but with my luck, the UPS was DOA. I have warrantied it back to the company and am awaiting the new UPS.

My new question is how do I reimport the ZFS array without it failing?

It is, but it is almost a month ago and it was from the U2 revision.
If you didn't change anything since then, it would be fine.

Thanks, I haven't changed anything since then. I'm still waiting for my Sinewave UPS to arrive so I can run my server safely from it. Hopefully, this will eliminate future problems. That being said, import of my existing ZFS array causes the kernel panic. I have not yet tried a new USB key, but reinstalls on that USB key appear to work up until I reimport my ZFS array. Is there a way to repair my ZFS array so that it loads up? I'd like to be able to save all the data on there if at all possible.

Thanks!
