发明名称 MIGRATION-DESTINATION FILE SERVER AND FILE SYSTEM MIGRATION METHOD
摘要 A migration-destination file server is coupled to a migration-source file server that provides a migration-source file system, and provides a migration-destination file system. The migration-destination file server comprises a storage device and a controller. When migrating a first hard-linked file, which is included in multiple hard-linked files referencing the same file management information in the migration-source file system, to the migration-destination file system, the controller stores data related to the first hard-linked file in the storage device, creates the first hard-linked file in the migration-destination file system, and creates a dummy hard-linked file for referencing the same file management information as the first hard-linked file in the migration-destination file server, and when migrating a second hard-linked file included in the multiple hard-linked files, the controller renames the dummy hard-linked file as a pathname of the second hard-linked file in the migration-destination file system.
