 The apiserver will allow for increases to storage requests in the `volumeClaimTemplates` component of a StatefulSet.
 
-During the StatefulSet update process, the StatefulSet controller will detect an update to a `volumeClaimTemplate` by comparing the updated and current revision of the StatefulSet.
+During the StatefulSet update process, the StatefulSet controller will detect an update to a `volumeClaimTemplate` by comparing the updated and current revision of the StatefulSet. This requires the `VolumeClaimTemplates` component of the StatefulSet to be recorded in the StatefulSet's `ControllerRevision` object.
 
 While updating a pod, the StatefulSet controller will update a referenced persistent volume claim object if its storage request in the associated `volumeClaimTemplate` has been increased.
 
-The pod will be restarted after the `FileSystemResizePending` condition is True on all updated persistent volume claims it references.
+The Statefulset controller will delete and recreate the pod after the `FileSystemResizePending` condition is True on all updated persistent volume claims it references. However, if the `ExpandInUsePersistentVolumes` feature is enabled, then deleting the pod is unnecessary to complete file system expansion on updated persistent volumes.
 
-### Risks and Mitigations
+The functionality provided by this enhancement will be gated by the `StatefulSetVolumeExpansion` feature gate.
 
-Under the `ExpandPersistentVolumes` feature, pods referencing a volume must be restarted for file system expansion to occur after the `FileSystemResizePending` condition is True on the persistent volume claim. If the StatefulSet is configured with the `RollingUpdate` update strategy, then the StatefulSet controller would need to wait for the `FileSystemResizePending` condition to be satisfied on each persistent volume claim referenced by the pod it is updating before restarting the pod. This could noticeably increase the update time of a StatefulSet with many replicas. 
+### Risks and Mitigations+
 
-A potential mitigation would be the eventual adoption of the `ExpandInUsePersistentVolumes` alpha feature in Kubernetes v1.11 which enables file system expansion on volumes being used by a pod.

+A potential mitigation would be the eventual adoption of the `ExpandInUsePersistentVolumes` feature, which enables file system expansion on in-use volumes thus, making it unecessary to delete and recreate any refrencing pods during volume expansion.
