i have installed TrueNAS Scale and since the installation either TrueNAS hangs or reboots on its own.
This morning the server hung again. There was no message on the monitor. TruNAS is simply frozen. After a restart I got the message that the middleware was not running, and I had to reboot. After that everything worked again.
Does anyone have an idea what this could be?
I have already replaced the board (BKHD NAS N100 DDR5 motherboard) with CPU and RAM. I have also increased the power supply.
An upgrade from TrueNAS 24.10.2-1 to 25.04-RC.1 did not bring any improvement. The kernel is probably not the problem.
System:
INTEL N100
16GB RAM non ECC
2 x Crucial 512GB M2
5 x Seagate 4TB HD
I suspect this might be a contributing factor, if they are SMR drives and deciding to fall offline/go non-responsive. Can you post the model number?
The N100 chip also has only 2 native SATA ports on its SoC I believe, so the other ports will have to have come from either an add-on chip (ASM1166/JMB585) or through a port multiplier.
What model are the Seagate drives - and how large is the power supply? Generally insufficient power is seen on boot time and manifests as drives failing to spin up when the inrush current spikes.
The controller is given for 5 ports, so there might be a port multiplier here.
We’ve seen here another N100 board having issues with cooling RAM. Run MemTest extensively and check temperature.
That’s my thought. If the JMicron is being hung off of a PCIe port then it will not be using a port multiplier, but if it’s actually the JMB575 then that might be the case.
Okay, but have you also verified RAM stability by running something like memtest86 overnight? I would describe N100 RAM compatibility as somewhat temperamental.
