    摘要: Mechanisms are provided for importing pre-existing data into a storage system utilizing a current storage management system that is different from an original storage management system used to create the pre-existing data. One or more data storage devices are integrated into the storage system in-place without modification of the pre-existing data stored on the one or more data storage devices. Metadata for the pre-existing data is created based on a linear progression of data in the pre-existing data. Read access requests targeting the pre-existing data are executed using the created metadata. Write access requests targeting the pre-existing data are executed by redirecting the write access requests to a copy of the pre-existing data created in another storage location.

    摘要: Embodiments include a method comprising detecting addition of a new nonvolatile machine-readable medium to a data storage pool of nonvolatile machine-readable media. The method includes preventing from being performed a first operation of a file system that requires a first parameter that identifies a logical indication of a location within the nonvolatile machine-readable media for the file system, until logical indications of locations within the new nonvolatile machine-readable medium for the file system have been stored in the data storage pool. The method includes allowing to be performed, prior to logical indications of locations within the new nonvolatile machine-readable medium being stored in the data storage pool, a second operation of the file system that does not require a second parameter that identifies a logical indication of a location within the nonvolatile machine-readable media, wherein the second operation causes data to be written into the new nonvolatile machine-readable medium.
