No Web or Local CLI access? Tips to prevent

[Shu]

Been running well for more than a month but started having issues accessing the UI from both WAN & LAN but my containers were still working (I even tried my local IP from a firefox container running on my machine. The login page loaded but signing in just kept spinning then future attempts didn't even show the login page).

Later in the night, I noticed my dockers were unresponsive (no Home Assistant, for example). Plugged a monitor into my machine and saw the CLI with weird text I assume were errors. I couldn't figure out how to reboot (I wasn't sure if I was logged in or not but couldn't figure out how to login if I wasn't).

Did a hard reset, nothing Unraid-related showed after my BIOS posted. After another unsuccessful hard reset, I went into the bios to confirm boot option (it was correct) and I changed boot wait time from 3s to 10s. Save & Reset then Unraid started to load/show. 

 

Attached diags.

Syslog looks normal to me, try booting in safe mode.

All is working fine now, so far. I was able to get in eventually. I was hoping something in the diags would point to the cause for this crash. Would booting in safe mode tell me more?

Only if normal boot doesn't work.

Perhaps the errors on the screen I saw didn't get mirrored to the syslog; I'll make sure to take a picture next time. All is seemingly fine now - maybe it was a cosmic bit flip. I'll come back if it happens again, hopefully next time with more helpful information (though, hopefully there is no next time)
