Swap the cards between the Pi 4 computers. If the fault moves with the card, the card is causing the node crashes. If the fault remains with the Pi, then something else is wrong.Hi,
I have three raspberry pi 4 (8gb) running a Kubernetes cluster with Ubuntu server and k3s. All pis are powered with PoE.
Some of the nodes crash periodically and then I can't ssh into them until I restart the pi.
They are not overloaded either on memory or CPU, so my best guess is that the storage (SD card) is causing it.
Is there any way that I can confirm that the memory card is causing the error?
