unraid stops working/crashes almost daily and needs hard reset

[dest0]

Hi there,

 

I'm running unraid and daily it seems to crash. I have to hard reset it. I'm not really sure on what next steps i should be taking for troubleshooting.  I've attached the diagnostics

ok thank you. I've disabled the global c-states. Will see how that goes for a while

[dest0]

Server froze up again yesterday. What else can I try?

[JorgeB]

Enable the syslog server and post that after a crash.

[dest0]

ok it crashed last night. i had enabled the syslog data capture before the tower-diagnostics-20211223-1056.zipcrash. Is this what you need or do i need to grab logs from somewhere else?

[dest0]

the crash was around 11pm pst last night

Yes, from where you chose to save them in the syslog server.

[dest0]

i told it to mirror locally in appdata, but i don't see a folder for logs so where do i grab them from?

[dest0]

[dest0]

syslogoh maybe this?

[JorgeB]

Nothing obvious logged, some strange SMB related errors, pool detected some corruption, which suggest possible RAM issues, crashes are likely hardware related.

memtest came back clear. What else do you suggest?

 

Is there a way to schedule a graceful reboot daily?  system seems to crash about 2 days after a reboot consistently

You can do this via the User Scripts plugin using the ‘reboot’ command.  This is equivalent to hitting the Reboot button on the Main tab, so you should test that you actually DO get a graceful reboot (in case there is something running that is preventing a graceful reboot). 

[dest0]

it took 25 minutes of looking around before i got this working. Incredibly frustrating

For the next poor soul that is searching, the information you need to set this up and have it working can be found in this post. Just the powerdown -r does not work

 

Do the moderators here have any suggestions regarding hardware diagnostics?

It's not easy to diagnose hardware without starting to swap some things around, like PSU, board, RAM, etc, one more thing you can try before that is to boot the server in safe mode with all docker/VMs disable, let it run as a basic NAS for a few days, if it still crashes it basically points to a hardware problem, if it doesn't start turning on the other services one by one.
