摘要： A storage system including: a storage device for storing a file; a plurality of file systems for managing the file; and a plurality of NAS servers that control access from a client to the file systems via a global namespace formed by grouping local namespaces for the one or more file systems; wherein, each NAS server includes a memory to store global namespace management information including global paths of the file systems; one NAS server of the NAS servers accepts a request to obtain snapshots of the file systems from external of the storage system; the one NAS server instructs itself and the other NAS servers to obtain snapshots of the file systems; the one NAS server and the other NAS servers obtain the snapshots of the file systems, and inform the one NAS server of snapshot identifiers and of local paths of the snapshots; the one NAS server makes snapshot management information including global paths of the snapshots based on each of the snapshot identifiers received from the other NAS servers and each of the global paths of file systems corresponding to the snapshots, included in the namespace management information so that both the global paths of the file systems and the global paths of the snapshots are configured on the same global namespace simultaneously, with a directory configuration of the snapshots being same in configuration layout as a directory configuration of the file systems; and the one NAS server informs the other NAS servers of the snapshot management information.

摘要： A storage system including: a disk device including an original volume and a plurality of snapshot generations; and a storage control unit which includes a processor unit. The processor unit receives write data to a storage area of the original volume, and determines whether data stored in the storage area of the original volume is already copied to the snapshot volume or not; if the data stored in the storage area of original volume is not already copied to snapshot volume, the processor unit copies the data from original volume to the snapshot volume, when a use capacity of the snapshot volume is larger than threshold amount by the copy, the processor unit indicates a specified snapshot generation, the processor unit migrates data of the specified snapshot generation from the snapshot volume to tape device; the processor unit deletes information of the specified snapshot generation in the snapshot volume.

摘要： A bicycle crank assembly has a right crank crimp-fastened to a crank shaft in such a manner that the external appearance is attractive. The crank shaft has a first and second portions with the second portion being positioned on the right side of the first portion and having a larger diameter than the first portion. The right crank has a sprocket mounting part, a right crank arm part, and an engagement bore formed in the center of the sprocket mounting part. The right crank is crimp-fastened to the crank shaft by installing the second portion of the crank shaft into the engagement bore and pressing the periphery of the engagement bore toward the outside in the axial direction of the crank shaft such that the pressed portion bulges radially inward and an annular space is formed between the crank shaft and the engagement bore.
