= Using the LVMS

The LVMS `StorageClass` is deployed with a default `StorageClass`. Any `PersistentVolumeClaim` objects without a `.spec.storageClassName` defined automatically has a `PersistentVolume` provisioned from the default `StorageClass`. Use the following procedure to provision and mount a logical volume to a pod.
