Hi @andyxning. Thanks for your PR.

I'm waiting for a kubernetes-csi member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

imo, Having all PVC labels on PV may not be ideal, considering the ownership of these objects are different. however lets get thoughts from others too @msau42 @jsafrane

I agree with @humblec, PV and PVC is a different object with a different purpose and blindly copying labels from one to the other is IMO bad. For example, copying bad topology labels could make a PV not usable.

At the same time, I see a good use case of copying some labels from PVC to PV, controlled by some policy. Just brainstorming an idea: there could be a list of labels to copy in a new StorageClass field.

Another question is when to copy these labels. If user adds a new label to a PVC that is already bound to a PV, should this label be copied to the PV too? Or when a new label is added to the policy, e.g. StorageClass suggested above, should it re-sync all existing PVCs/PVs?

This will need broader discussion among sig-storage folks. cc @gnufied @msau42 @xing-yang @saad-ali

I agree that this way may not be a good choice to pass some labels from pvc to pv. All i want to do is we need a way to pass some labels to pv from pvc.

Another question is when to copy these labels. If user adds a new label to a PVC that is already bound to a PV, should this label be copied to the PV too? Or when a new label is added to the policy, e.g. StorageClass suggested above, should it re-sync all existing PVCs/PVs?

This is not the objective for my initial PR. The coordination of pvc labels and pv labels is not needed, imho. After initial settings of pv labels, the updation of pvc labels does not need to propagate to pv since they are not the relation like deployment and pod.

Friendly Ping @xing-yang @jsafrane @humblec

@andyxning: this change has no tests. Can you add some?

I agree with @jsafrane that this needs more discussion.

@andyxning Can you elaborate your use case for copying these labels?

It almost feels like there should be pvc.spec.persistentVolumeTemplate, at least with annotations and labels. And perhaps with a way how to transform some PVC fields into PV labels / annotations.
