Hello guys, sorry I'm really in trouble because everything I use daily is on my unraid server as well as my smart home. Randomly, at 8am, while I was sleeping, the server died. I could not open the WebGUI of unraid anymore, so I did an unclean shutdown.

I restarted it and thought it was over, or some hardware died (even though the server was still running technically before). Unraid was able to boot again (felt longer than normally) and now everything looks normal but the Docker Service failed to start. And I need to know what the reason of the crash was. This never ever happened.

I hope the diagnostics have information about the crash. I could not really find out what the reason was...

So thankful for any help here.

The syslog in the diagnostics is the RAM copy and only shows what happened since the reboot.   It could be worth enabling the syslog server to get a log that survives a crash/reboot so we can see what happened prior to the reboot. The mirror to flash option is the easiest to set up, but if you are worried about excessive wear on the flash drive you can put your server’s address into the Remote Server field.

@itimpi thank you for the quick reply. I had the syslog server set to this:

But there are no logs/syslog-previous.txt for me.

And honestly, I only got the unraid server in use. There is no other server, so I don't know how to set up a remote syslog server. I know that mirroring to flash is not made to be used all the time.

That has only set the syslog server into ‘listen’ mode! To get it to actually start recording you either need to set the mirror to Flash option OR put your server IP address into the Remote Server field as mentioned in the link.
