Once I create a statefulset, I could see pvc and pv being created and are in bound state
kubectl get pv
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE
pvc-aa65bc02-d0bf-432d-a943-dc1223e03687 20Gi RWO Delete Bound enterprise/data-sceptre-themes-manager-0 local-path 2d8h
kubectl get pvc -n enterprise

I ssh into the statefulset container and I could see the /storage is mounted.
root@sceptre-themes-manager-0:/usr/src/app# df -h

I go to /storage dir and touch a file called test. Then I delete the stateful, I could see the pvc and pv remains intact in bound state. I recreated SFS and ssh into new container and this test file is gone. I could see a proper 777 permission directory is getting created inside /var/lib/rancher/k3s/storage/ for this volume.

Any idea what might be wrong. Is there something here I am missing?
