Document Type and Number:
Japanese Patent JP4146380
Kind Code:
B2
Abstract:
A fragmentation information collecting section in a file system control section collects fragmentation information on a target volume for which a fragmentation state is to be eliminated, the target volume being managed by a file system. An analysis section in the file system control section analyzes the fragmentation state of the target volume on the basis of the fragmentation information collected, to generate block rearrangement information required to eliminate the fragmentation state of the target volume. A block rearrangement command generating section in the file system control section generates a block rearrangement command row corresponding to the block rearrangement information. A disk array control device executes the block rearrangement command row to eliminate the fragmentation state of the target volume.
