TrueNas Scale server silent shutdown

[greentin]

Hi guys,

It is the second time in a month that I encounter a strange behavior of my TrueNas Scale server (22.02 -RC2).
My system goes offline without any apparent reason. I have access to the IPMI of my motherboard but can't reboot the system via the IPMI software. I have to do a hard reset, turning off and on the system. After that Truenas Scale boot normally.
I never had such problem with TrueNas Core.

I have checked the logs but can't find any reason causing these sudden silent shutdowns of my server. Any idea where to look?

My system specs :
Case : Fractal Node 804
PSU : Seasonic Prime TX (650W)
Motherboard: Supermicro X11SCH-F
CPU: Intel Xeon E-2226G 3.4 Ghz
CPU cooler: Noctua NH-U12S
Ram : Samsung M391A4G43MB1-CTD 32 Gb DDR4 - 2666 Mhz ECC
HDD: 4x 4Tb WD RED PLUS (CMR)
SSD: Supermicro SATA DOM 32 Gb
SSD: Intel Optane 800p 58 Gb

Thanks for your help.

Hi greentin,

Did you find the cause and solution for this problem? I'm curious because I'm having the same issue with my system. I thought it was RAM because I only have 12 GB, but I see your system had 32 and it was still happening. Any insight would be appreciated!

I'd look for hardware problems.

First, RAM, not the amount but quality (i.e. try other sticks).
Second, bootable disk (USB, DOM, etc.), try a different one...

Thank you! I didn't realize the quality of the hardware might cause that kind of problem. Most of it is scavenged from an old Dell xps pre-built. The boot drive is a cheap generic ssd.

The boot drive is a cheap generic ssd.

Then try replacing this first...

In most cases I encountered, faulty RAM causes random reboots.
Faulty storage devices more often cause freezes...
