Zusammenfassung:A method for reprovisioning a logical storage volume (151) for an application running in a computer system (100) that is connected to a storage system (130) via input-output command, IO, paths (601) and non-IO paths (602). The method comprises issuing (1716) a request to the storage system (130) via a said non-IO path (602) to increase a size of the logical storage volume (151) provisioned in a selected logical storage container (142); receiving acknowledgement of the increase in size from the storage system (130); and updating (1718) a metadata file associated with the logical storage volume (151) to indicate the increased size.
