So, for a while now i am experiencing random server crashes.

Sometimes the server is running fine for a week or two, sometimes only for a day.

 

Most of the crashes happen at night when i am not using the sever actively, but background stuff is happening. 

When i say crash i mean that the server is completely unreachable. No WebUI, no SSH.

I have switched most of the Hardware recently (MoBo, CPU, RAM) and the Crashes happen on both sets of Hardware, so i guess it might be Software related or a problem with the drives.

On the other Hardware i had VGA Output and the last Messages where about Kernel Panic, but i don't have the exact error since i switched back to my old setup again and that does not have a running VGA output.

 

I have gathered:

- Diagnostics after i restarted the server

- SMART Logs for the three drives that have warnings (Parity + 2 Array drives)

- LOG.txt the last hours of syslog from the USB BEFORE the restart.

 

I have activated Syslog Server but i am not quite sure where the syslog is saved besides the Flash drive, since it just says <custom> under Settings-> Syslog -> Location

I have also activated Mover Logging since the drives and the Software are the common denominators between both setups.

 

 

What i have done so far:

a while ago i started a reddid thread but i was not at home so could not follow through with all suggestions in real time: 

-  switched from macvlan to ipvlan

- i update all my docker containers at least once a week

 

 

My Hardware currently:

BIOS: American Megatrends Inc. Version 2.1. Dated: 03/17/2012

Memory: 80 GiB DDR3 Multi-bit ECC (max. installable capacity 384 GiB)

OpenSSL: 1.1.1q

I hope i have gathered all the right stuff to get some help  Feel free to ask for more

Enable the mirror to flash drive option in the syslog server and post that after a crash.

This should be the other way around.

ok, i activated the mirroring, and yes you are correct. I switched from macvlan to ipvlan  i will fix that in the post

OK, i just had an other crash, here is the syslog. Hope this helps

 

syslog-1683021113

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.

ok, since i have swapped all the Hardware exept Power already i guess it would be one of the drives? Any Idea how to check them if my smart reports dont show much?

Unlikely that a problem with one of the drives would make Unraid crash without anything logged, PSU would be a possibility.

oh... ok... how would i go about checking that? Just Buy a new PSU and hope that fixes it?


I have it running in safe mode now and will for a week or so. But how do i go about turning on the services one by one? can i do this from safe mode or what would be the ideal way?
And with services do you mean Plugins/Docker/ VM or individual plugins and docker containers? Just trying to make sure i get everything right

Docker and VMs can be run in safe mode.
