You recently deployed an application to GKE where Pods are writing files to a Compute Engine persistent disk. You have created a PersistentVolumeClaim (PVC) and a PersistentVolume (PV) object on Kubernetes for the disk, and you reference the PVC in the deployment manifest file.
You recently expanded the size of the persistent disk because the application has used up almost all of the disk space. You have logged on to one of the Pods, and you notice that the disk expansion is not visible in the container file system. What should you do?
