I have a Kubernetes cluster on Google Cloud Platform. It has a persistent Volume Claim with a Capacity of 1GB. The persistent volume claim is bound to many deployments.

I would like to identify the space left in the persistent Volume Claim in order to know if 1GB is sufficient for my application.

I have used the command "kubectl get pv" but this does not show the storage space left.

If there's a running pod with mounted PV from the PVC,

kubectl -n <namespace> exec <pod-name> df

...will list all file systems, including the mounted volumes, and their free disk space.
