GPU resources are not recovered even XID error is resolved

[jslouisyou]

Hello, NVIDIA team.

I recently faced an issue while GPU resources (nvidia.com/gpu) can be shown from kubelet are not recovered (e.g. 7 -> 8) even any XID error is resolved.

I got nvidia-device-plugin-daemonset from gpu-operator and I'm using gpu-operator v23.9.2.

Here's more details:

I found that there were only 7 GPU cards shown from Kubernetes, even I'm using 8 GPU cards in H100 node:

Capacity:
  cpu:                        128
  ephemeral-storage:          7441183616Ki

  hugepages-2Mi:              8448Mi
  memory:                     2113276288Ki
  nvidia.com/gpu:             8
  pods:                       110
Allocatable:
  cpu:                        128
  ephemeral-storage:          6857794809152
  hugepages-1Gi:              0
  hugepages-2Mi:              8448Mi
  memory:                     2062682496Ki
  nvidia.com/gpu:             7       <=========== here
  pods:                       110

nvidia-device-plugin-daemonset reports that there is XID 94 error is coming out in one of GPU card:

But after elapsed some time, it seems that XID error is somewhat resolved (I think application is restarted or removed). I can't find XID error from nvidia-smi:

But even if XID error is resolved, nvidia-device-plugin-daemonset won't try to fetch new status of GPU cards and reports to kubelet, so kubelet thinks that only some of GPU cards can be used.

After I restarted nvidia-device-plugin-daemonset pod, at then it reports kubelet that they can use 8 GPU cards (the number of nvidia.com/gpu is changed in Allocatable):

Capacity:

I think nvidia-device-plugin-daemonset should fetch status correctly and report to kubelet.
Could you please take a look this issue?

Thanks.
