Debugging NVIDIA Graphics Cards on Talos Linux

This guide outlines the procedure for debugging NVIDIA graphics cards on a Talos Linux node. Due to Talos Linux's immutable and secure nature, direct driver installation and typical debugging steps are not possible. Instead, we leverage Kubernetes features and NVIDIA's containerized drivers.

Procedure:

1. Run the Debug Pod:

   Execute the following kubectl command to launch a privileged debug pod on the target Talos Linux node. This pod will contain the NVIDIA driver binaries.

kubectl get pv -o=jsonpath='{range .items[*]}{.spec.csi.volumeHandle}{"\t"}{.spec.claimRef.namespace}{"/"}{.spec.claimRef.name}{"\n"}'

IMAGE=pool_name/image_name
rbd feature enable $IMAGE exclusive-lock

rbd object-map rebuild $IMAGE
rbd du $IMAGE

# Enabling for all images in a pool
POOL=pool_name
for IMAGE in $(rbd ls $POOL); do if rbd info $POOL/$IMAGE | grep -q object-map; then echo "$POOL/$IMAGE has been processed"; else echo "processing $POOL/$IMAGE" && rbd feature enable $POOL/$IMAGE exclusive-lock && rbd feature enable $POOL/$IMAGE object-map && rbd object-map rebuild $POOL/$IMAGE; fi ; done
