First random weirdness

[whipdancer]

After about 9 years of using Unraid, I experienced my first set of seemingly bizarre issues.

It seemed to occur overnight: 3 docker images disappeared, 2 other docker images quit functioning, 1 docker image showed as orphaned, 1 data drive reports no file system, and random CPU spikes hitting 100%.

• Plex and Jackett dockers disappeared.
• Deluge quit working (I could get into the UI for it, but all downloads reported errors).
• Tautulli quit working (It showed as running the but UI wouldn't load).
• Radarr docker showed up as orphaned.
• One data disk now shows as having no file system.

I dug into the logs as best as I could, but I really didn't see anything obvious. After shutting everything down and rebooting, I have restored/re-installed the dockers as appropriate, kicked off a long smart report on the drive and it seems like everything is working again.  No other drives report errors or are missing or anything like that.

The dockers/apps that I re-installed all picked up with data intact as if nothing had happened, and the CPU spikes seem to have stopped.  I will be testing drive 12 (the drive missing the file system) more to see if anything else turns up - but the smart report is clear for it.

I'm at a loss to explain what happened, so if anyone has any ideas I'd love to hear them.

Really needed to see the diags before rebooting to help further. Sounds very bizarre though!

Yeah, I didn't think about preserving them until I had rebooted.  Hopefully I'll remember to do it if next time happens.
