ABSTRACT:
An operating system-independent file map generator generates an operating system-independent map of a file stored on a mass storage subsystem, the mass storage subsystem including at least one storage device, the at least one storage device including a series of blocks, and the file being stored on a least device extent comprising at least one block. The generator comprises a file identifier receiver, a query module and a file map entry generator. The file identifier receiver receives a file identifier for the file. The query module queries a volume manager to obtain disk extent information for the file identified by the file identifier, the disk extent information identifying the at least one extent. The file map entry generator generates a file map entry for the file map for the file, the file map entry including the disk extent information obtained by the query module.
