- pod-0 k8s 85.9G => from the Pod, shows the space of PVC.
- kube metrics 96.78G => from the kube Metrics
- Netap metrics 79.34G => from NetApp Metrics "volume_size_used", which has the same value shows in AIQUM

There are a gap between these three numbers: 85.9G, 96.78G, 79.34G, what could be the reason resulting the gap.
Is the "volume_size_used" querying the same data source as "volume_space_physical_used"?
