Unable to run pod on G5 48xlarge instance, other g5 instance works well

[arpitsharma-vw]

1. Quick Debug Information

• Container Runtime Type/Version(e.g. Containerd, CRI-O, Docker): CRI-O
• K8s Flavor/Version(e.g. K8s, OCP, Rancher, GKE, EKS): Openshift v4.13.23
• GPU Operator Version: 23.9.1 , gpu-operator-certified.v1.11.1

2. Issue or feature description

We have openshift cluster where we have installed nvidia gpu operator. When we run any pod on G5.48xlarge machine, we get error as

Allocate failed due to device plugin GetPreferredAllocation rpc failed with err: rpc error: code = Unknown desc = error getting list of preferred allocation devices: unable to retrieve list of available devices: error creating nvml.Device 0: nvml: Unknown Error, which is unexpected

Same pod on other machine like g5.4xlarge,g5.12xlarge works well. We see this behaviour recently. Earlier same pod worked on g5.48xlarge instance.

We also see pod from nvidia-dcgm-exporter is failing with following error:

(combined from similar events): Error: container create failed: time="2023-12-13T11:17:30Z" level=error msg="runc create failed: unable to start container process: error during container init: error running hook #0: error running hook: exit status 1, stdout: , stderr: nvidia-container-cli.real: detection error: nvml error: unknown error\n"

Error: container create failed: time="2023-12-13T10:29:12Z" level=error msg="runc create failed: unable to start container process: error during container init: error running hook #0: error running hook: exit status 1, stdout: , stderr: nvidia-container-cli.real: initialization error: driver rpc error: timed out\n"

3. Steps to reproduce the issue

Assign pod on g5.48xlarge works, but it doesn't run

4. Information to attach (optional if deemed irrelevant)

• kubernetes pods status: kubectl get pods -n OPERATOR_NAMESPACE
• kubernetes daemonset status: kubectl get ds -n OPERATOR_NAMESPACE
• If a pod/ds is in an error state or pending state kubectl describe pod -n OPERATOR_NAMESPACE POD_NAME
• If a pod/ds is in an error state or pending state kubectl logs -n OPERATOR_NAMESPACE POD_NAME --all-containers
• Output from running nvidia-smi from the driver container: kubectl exec DRIVER_POD_NAME -n OPERATOR_NAMESPACE -c nvidia-driver-ctr -- nvidia-smi
• containerd logs journalctl -u containerd > containerd.log

@shivamerla Hi, Can you help here? Many thanks :)

[shivamerla]

@arpitsharma-vw can you check dmesg on the node and report any driver errors. dmesg | grep -i nvrm. If you see GSP RM related errors please try this workaround to disable GSP RM.

[chiragjn]

please try this workaround to disable GSP RM.

@shivamerla What if the driver is already installed (as is the case with EKS GPU AMI), will the driver component still try and apply the kernel module config?

[arpitsharma-vw]

Many thanks @shivamerla for your input. I can confirm that we see GSP RM related errors here. But regarding the fix, we have installed the GPU operator via OLM(not Helm). I am afraid that these changes will get wiped out again on the next upgrade.

[empovit]

Let me explain how this can be done on OpenShift:

First, create a ConfigMap as described in the doc for disabling GSP RM.

oc create configmap kernel-module-params -n nvidia-gpu-operator --from-file=nvidia.conf=./nvidia.conf

Then add the following to the ClusterPolicy:

  driver:
    <...>
    kernelModuleConfig:
      name: kernel-module-params
    <...>

You can do it either via the Web console, or using this command:

oc patch clusterpolicy/gpu-cluster-policy -n nvidia-gpu-operator --type='json' -p='[{"op": "add", "path": "/spec/driver/kernelModuleConfig/name", "value":"kernel-module-params"}]'

Essentially, the outcome should be the same, no matter if done via Helm or using the method I described. That is, the ClusterPolicy resource will have the right section added to it. The oc patch command above assumes that there is already a ClusterPolicy resource, but you can also add the required kernelModuleConfig section right away when creating the ClusterPolicy (via the Web console or from a file).

I believe that the changes will persist as they will be part of the ClusterPolicy. Also, the operator will probably restart the driver to pick up the changes. Please correct me if I'm wrong @shivamerla

[farioas]

Same here. I'm using EKS 1.29 with the latest AMI with "a fix" awslabs/amazon-eks-ami#1494 (comment).
Gpu-operator v23.9.1

Even the DCGM exporter failed to start with a message:

      Message:     failed to create containerd task: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error running hook #0: error running hook: exit status 1, stdout: , stderr: Auto-detected mode as 'legacy'
nvidia-container-cli: detection error: nvml error: unknown error: unknown

[farioas]

After applying a suggest fix with disable of GSP:
