unRaid crashed loop2 error

[joshopkins]

I found that my unRaid server had crashed. I was able to restart it and when I logged in it showed that docker was offline. I tried to disable and re-enable the service. When that did not work I looked in the logs and it shows the following

I looked at the smart reports for my disks and while some show some non-critical errors it says that all disks have passed. I have attached the diagnostics.

 

Not sure where to look or what to do from here.
