Abstract
While providing a storage service to a client system, a storage system maintains a complete set of storage service metadata for the service on the same storage device that stores the user data received from the client system. When an event is detected that requires the storage service to be moved to a new storage system, the storage service can be moved to a new storage system by moving the storage device containing both the user data and the storage service metadata to the new storage system. The new storage system detects the storage device that has been moved, and detects the storage service metadata and user data. The new storage system then uses the storage service metadata and user data from the storage device to immediately reestablish the storage service with the client system, without having to perform a separate step of copying the storage service metadata from the previous storage system.
