= Expanding local volumes
You can manually expand persistent volumes (PVs) and persistent volume claims (PVCs) created by using the local storage operator (LSO).
.Procedure
. Expand the underlying devices, and ensure that appropriate capacity is available on theses devices.
. Update the corresponding PV objects to match the new device sizes by editing the `.spec.capacity` field of the PV.
. For the storage class that is used for binding the PVC to PVet, set `allowVolumeExpansion:true`.
. For the PVC, set `.spec.resources.requests.storage` to match the new size.
Kubelet should automatically expand the underlying file system on the volume, if necessary, and update the status field of the PVC to reflect the new size.
