@infa-kvaibhav this will almost certainly be an issue with your cluster not provisioning or binding the PersistentVolume correctly to the Pod.

Search around for running PreBind plugin "VolumeBinding": binding volumes: timed out waiting for the condition based on whatever CSI driver you are using.

Also, check the logs of the Pods for your CSI driver.

Because this is unrelated to the chart, I am going to close it, but feel free to provide an update if you figure out what was wrong with your cluster.
