2 months ago Hey, seems that you don't have the required SriovOperatorConfig named default.
It can be created with helm using the following parameters: https://github.com/k8snetworkplumbingwg/sriov-network-operator/tree/master/deployment/sriov-network-operator#sr-iov-operator-configuration-parameters

2 months ago @rollandf Thank you. set sriovOperatorConfig.deploy to true in default values.yaml, ran helm upgrade, the config daemon is up.
Compared to the example in quick-start, we're still missing the service obj, is that expected? shall we create the svc manually?

2 months ago Hi @hymgg there is a bug you can see the PR https://github.com/k8snetworkplumbingwg/sriov-network-operator/pull/679
in general please check your nodeSelector in the sriovNetworkNodePolicy can you do
kubectl -n sriov-network-operator get sriovnetworknodepolicy -oyamlI think your node selector is not right and it gets empty selector that triggers the bug
hymgg
commented
2 months ago @SchSeba The SriovNetworkNodePolicy spec was pasted in my last comment. original nodeSelector from quickstart example was feature.node.kubernetes.io/network-sriov.capable: "true", but I didn't find any node with that label, so changed it to node-role.kubernetes.io/worker:, then daemonset.apps/sriov-device-plugin found 3 nodes and started 3 pods. Shall I instead keep the original nodeSelector and label the nodes accordingly?
Thanks. -Jessica policy-ens1f1.yaml.txt

2 months ago @hymgg I ran into this almost 8 months ago. Almost everything in your post. On a single node, clean test cluster this thing works. But our nodes have hundreds labels.
Are your clusters rke?
Generally this project did not seem great. Just even that the labels are hard coded is absolutely terrible.
I'm already not looking forward to trudging down this path again.

are the created SR-IOV virtual functions bound to intel driver ? from the logs it doesnt seem so.
is the VF driver installed in your OS ?
does cat /sys/bus/pci/devices/0000\:3b\:00.0/sriov_drivers_autoprobe return 1 ?

2 months ago @SchSeba One of my biggest issue with that labels were hardcoded in the code. It didn't have a configurable option. I can hack around, I'm a good dev when I need to be. It was just a pain.
Then I hit the segfaults same as this post and I called it. I just took a look at issues before I started again. For our current configurations we laid down the plugin manually. We have new node configurations coming as well as some other requirements so it was just more manual config or trying this.
I should add too, same node, minikube, no segfaults. Production cluster config, seg faults.
I'll track it down, im just not excited about it.
https://github.com/k8snetworkplumbingwg/sriov-network-operator/issues/507
I'm sorry I've not been good with responses. I'm a little selfish in this. I at least do give some break fix
edit: There's a helm chart: https://github.com/k8snetworkplumbingwg/sriov-network-operator/tree/master/deployment/sriov-network-operator#sr-iov-operator-configuration-parameters
Idk why the quick start doesn't lead with this, and instead uses this custom make system. Seems like it's just a docs gap.

1 month ago Hi @hymgg,
Sorry for the late response. To be sure there is no problem from the operator system point of view please try
echo 5 > /sys/bus/pci/devices/0000\:3b\:00.0/sriov_numvfsif that returns and error then the problem is something in the operating system/drivers and the operator will also not be able to configure the virtual functions.
you can try to check with dmesg after the echo command to see if the drivers print any error.

Can you also share the a kubectl cluster-info dump -n <operator-namespace> --output-directory <xxx>?

so, the problem here is that on the VF driver. Can you check that when you manually create VF (echo 5 > /sys/bus/pci/devices/0000:3b:00.0/sriov_numvfs) the network devices appear in the system (i.e. you can see them via ip link show).
If they don't spawn, there is a problem with the drivers and we have to check the kernel journal.

Removed SriovNetworkNodePolicy to restore node/pod to healthy state.

Install using helm was much easier than following the quick start steps. However, it only brought up the sriov-network-operator pod, according to quick start guide, there should be a sriov-network-config-daemon too?
