Identify cause of crash

[X4V1]

My proxmox node crashed yesterday. The computer was still on (power led) but nothing was accessible anymore (gui, ct and vm were down). The node did not reboot. I had to force restart the node (pressing the hardware button).

On the following screenshot you can see that there is a gap between 10:30pm and 11:30pm.


I would like to understand what happened but I can't find anything in logs.

I have no informations between 10:30pm and 11:30pm. I wanted to check system logs so I tried to run the command:

journalctl --since "2024-02-27 22:20:00" --until "2024-02-27 22:32:00"

but logs are empty.

Could you please help me to figure out what happened ? I'm not a linux expert and I'm not really sure where to start investigation from.

The command only seems to check from 10.20pm to 10.32pm. You might wanna extend the timeframe. Also - I assume you are running the command as root? Since otherwise you wouldn't get any important system messages.

Can you post the output of:

journalctl --since "2024-02-27 22:00:00" --until "2024-02-27 23:30:00" > syslog.txt

This should create a syslog.txt in your working directory which you can then download via e.g. scp (linux) or WinSCP (Windows)

@shanreich Thank you for your help.
I already tried to expand the timeframe but I'm not seeing any relevant log (to me at least).
I'm attaching the log file requested here, maybe you or someone else will see something that I missed.
