DCGM initialization error

[AnkitPurohit01]

1. Quick Debug Checklist

• Are you running on an Ubuntu 18.04 node?
• Are you running Kubernetes v1.13+?
• Are you running Docker (>= 18.06) or CRIO (>= 1.13+)?
• Do you have i2c_core and ipmi_msghandler loaded on the nodes?
• Did you apply the CRD (kubectl describe clusterpolicies --all-namespaces)

1. Issue or feature description

We installed Nvidia GPU operator version 1.7.1 on our kubernetes cluster using HELM.
But there seems to be DCGM initialization error and GPU resources are not discovered by the node

Please check the following logs

2. Steps to reproduce the issue

@AnkitPurohit01 Can you get logs from device-plugin-daemonset pods? I see that some of those pods have restarted, so the logs might help. Also please run this command from any of the worker nodes and attach along with syslog. /run/nvidia/driver/usr/bin/nvidia-bug-report.sh

did you found a solution or cause to this problem @AnkitPurohit01 ?

[francescov1]

For anyone still looking, I found this solution worked for me: NVIDIA/dcgm-exporter#59 (comment). And there's some additional info about the solution here: NVIDIA/gpu-monitoring-tools#96 (comment)
