Hey Lads,

since little bit more than 2 Weeks Unraid started to crash suddently. First i didn't realize it only Friday when parity sync was starting while i did the last three days ago. Now run 100 Loops memtest and Memory is fine.

Today it already crashed two times out of sudden. No heavy usage etc.

C246M-WU4-CF

Xeon E-2144G

64 GB DDR4 ECC

RTX 3090 FE

Unraid 7.2.4

Asus Rog 850W PSU

Unraid running on Cruzer FIT USB Sick

Any ideas ?

This is a little unclear. I assume you mean you are getting parity check due to unclean shutdown, not that you are running these parity checks intentionally.

Setup syslog server.

Hey Trurl,

ah sorry. Yes it's like you have understood. I'm getting parity check due to unclean shutdown. I have not realized the crashes but then i realized the parity checks and kept monitoring it and the server just crashed 4 - 5 times without any notice. Just rebooted.

I've now setup local syslog. So now i'm waiting for the crash and then upload again ?

Do that but a server rebooting by its own is almost always a hardware issue, and there may not be anything relevant logged.

Hey,

thanks for the feedback. When disabling the NVIDIA driver, the crashes are gone. Tested at 3090 in another PC and it's running the stress test flawlesly. retried it with Unraid and older driver, but unraid still crashes suddently.

Now im undecided if the PSU is faulty, the motherboard is faulty or if its related to the Nvidia Driver Plugin....

Does this happen when the GPU is under significant load on the unraid system or when it's idle?

If it occurs when the GPU is under heavy load it is probably the PSU having a problem supplying power to the GPU.

Didn't want to believe it but after undervolting the GPU system became stable. Now change the PSU for another one and all is solid again also without undervolting. THave not expected to have a dying 2 year old Asus Rog PSU...looks like not only their Mobo are .....
