@cdesiniotis Have you seen this error?

[cdesiniotis]

@lengrongfu I am not familiar. It is recommended to blacklist nouveau as it can conflict with the nvidia driver.

I am using gpu-operator to install the driver. Do I need to manually add nouveau to the blacklist before installing gpu-operator?

k8s-driver-manager pod exec rmmod nouveau error. https://github.com/NVIDIA/k8s-driver-manager/blob/659892aea6af4442e6e63b8a97cadc838c84782c/driver-manager#L494

This is not a required pre-requisite, but because you are seeing errors from nouveau I recommended that you try blacklisting it. Like you pointing out, we do take care of unloaded in the module.

Ok, thanks, i exec blacklist nouveau after, k8s-driver-manager can exec success,

@cdesiniotis Let's discuss whether it is possible to develop a new feature to add an option to k8s-driver-manager to perform the operation of blacklist nouveau

[cdesiniotis]

Since blacklisting would require updating the initramfs and rebooting the node, it is not something we would be open to adding to this component. This should be done during infrastructure provisioning.
