Abstract:

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.
