Unraid server suddenly becomes unable to operate and must force shutdown

[severanced]

Hello, I've been having an issue for the past several months and I'm hoping that I can get some direction on it, I've had an issue where, without warning, my Unraid server looses all connectivity and basically freezes, I can't get anything to show up on screen on the machine itself, and, obviously I'm not able to connect to it. I'm using version 6.12.3.

 

I have to force an unclean shutdown and, of course, a parity check has to ensue once it starts up, I I don't think it's a network issue or power issue and I thought it might be an issue with the USB drive so I replaced it entirely but the issue continued happening, is there anything I can look for, logs or whatever to possibly find out what the issue is?

Enable the syslog server and post that after a crash together with the diagnostics.

Thanks, I've got one set up so I'll see what happens with the next crash.

Hi, My server had a hard crash again and I had to do a hard shutdown. I was able to pull some syslogs and some diagnostics, I hope these will point to something that might be causing the crash.

Unfortunately there's nothing relevant logged, this usually points to a hardware issue, one thing you can try is to boot the server in safe mode with all docker/VMs disabled, let it run as a basic NAS for a few days, if it still crashes it's likely a hardware problem, if it doesn't start turning on the other services one by one.

Thanks, I've been buying parts to build a new server, motherboard, memory Etc. My concern with these crashes was that I was going to be taking a piece of hardware that was causing the crash to the new server.
