STORAGE SYSTEM, BLOCK RELOCATION CONTROL METHOD, AND PROGRAM

摘要

PPROBLEM TO BE SOLVED: To make it possible to solve a fragmentation status in a volume at high speed. PSOLUTION: A fragmentation information collecting section in a file system control section 124 collects fragmentation information in an object volume which is managed by a file system 122, and solves the fragmentation status. An analysis section in the file system control section 124 analyzes the fragmentation status of the object volume based on the collected fragmentation information, and generates the block relocation information for solving the fragmentation status of the above object volume. A block relocation command generating section in the file system control section 124 generates a series of block relocation commands corresponding to the block relocation information. A disk array control unit 112 solves the fragmentation status of the above object volume by executing this series of block relocation commands. PCOPYRIGHT: (C)2006,JPO&NCIPI
