For OceanStor V700R001C10 as well as OceanStor Dorado V700R001C10 and later versions, the minimum capacity of a file system after capacity expansion is limited. For details, see the product documentation of the corresponding storage device.

When the capacity of a PVC used by a container is insufficient, you need to expand the capacity of the PVC.

Prerequisites

A PVC has been created, the backend to which it resides exists and supports capacity expansion.
