// we bypass the check for VolumeExpansionPendingOnNode state during the pre-check
// and then directly call the NodeExpandVolume method on the plugin.

// However, it does not make sense where the csi driver does not support node expansion.
// We should not treat this as a failure. It is a workaround for this issue:
// https://github.com/kubernetes/kubernetes/issues/131381.
//
// For other access modes, we should not hit this state, because we will wait for
// VolumeExpansionPendingOnNode before trying to expand volume in kubelet.
// See runPreCheck() above.
//
// If volume is already expanded, then we should not retry expansion on the node if
// driver returns OperationNotSupportedError.
