Thanks so much in advance,

After a graceful restart of nodes, I'm experiencing an unusual access denied error on the pvc used for llm model cache stored on a local-nfs storage class.

This is causing pods to be stuck in ContainerCreating status.

videosearch        vss-blueprint-0                                                   0/1     ContainerCreating   0              20h    <none>            worker-1    <none>

vllm               llama3-70b-bc4788446-9q8c2                                        0/1     ContainerCreating   0              21h    <none>            worker-2    <none>

The pv and pvc are both healthy, it seems just the mount command that the pods are issuing is failing.

My previous solution was to delete the pv and pvc and then redeploy the entire helm chart, but this is not ideal to have to redeploy a major workload after restart.

Would anyone happen to have a suggestion for something like this?
