I was trying to create a pvc with RWX access mode in the kind cluster. I see an error that it is not supported.

I was using kind cluster to create resources. As part of that I was creating a pvc with RWX access mode. I see the kind cluster comes with standard storage class as below-

NAME                     PROVISIONER             RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
standard (default)   rancher.io/local-path   Delete                   WaitForFirstConsumer         false                                         12h

It looks like the default storage class not allow to create pvc with Read Write Many access mode. Whereas the default storage class in minikube cluster environment allow us to create pvc with RWX mode.
Below error seen in pvc -
rancher.io/local-path_local-path-provisioner-bd4bb6b75-sbf49_ccebea37-56a9-405c-b76b-3cd0e113fb23 failed to provision volume with StorageClass "standard": Only support ReadWriteOnce access mode

Can someone please let me know if something is missing or is it a known issue?

I think this is a limitation of rancher.io/local-path ,rancher/local-path-provisioner#70

Unlike minikube we need to support multi-node clusters. We use the driver above.

Most clusters do not have readwritemany out of the box. If you're not doing a special cased single node cluster where you can just bind mount a folder to all the pods you need some synchronized network attached storage like NFS. See #1487

@BenTheElder: The label(s) kind/feeature cannot be applied, because the repository doesn't have them.
