HiveOS crashing intermittently - how to tell which GPU failed?

Nvidia Cards
1

Hi everyone
I have 10 Nvidia cards in my rig, and the stupid thing crashes every hour or so, sometimes less, sometimes more.

Sometimes a GPU will crash (Trex miner will say ‘get get temperatures’ or something), and sometimes the OS will just hang and crash completely (cant ping the machine, yet it stays on and doesnt reboot and shows up as ‘offline’ through the web interface)

Is there any way to see what GPU is causing the problem? I would assume that its probably one card that is finicky, crashes, and takes down the whole machine.

Heres an example, rig crashes at ~11:23pm. This is what I can find from the various logs:

Is this the line I am looking for?
Oct 14 23:23:32 Main kernel: [ 992.409856][ T3736] NVRM: GPU Board Serial Number: 156xxxxxxxx097

Does that mean the GPU with that serial number crashed?

PCI:0000:2c:00 this is what you are looking for. In Hive Under every GPU number there is a series of digits.
check which one is 2c:00.0. i think this should be the one. do you have such number under one of the GPUs? also you can try by disconnecting one by one and see if it doesnt crash.

Hi All,

Sorry to bumping an old thread. but i do have similar issue, sometimes the rig just froze.
I notice that OP got some log there, any kind soul can guide me how to reach the logs?

should i activate the watchdog?

thanks!
