Abstract
A storage system stores data in at least one partition of a physical storage media in accordance with file system information specifying a plurality of logical blocks having logical block addresses within the partition. The logical blocks include excess logical blocks that are not mapped to space in the physical storage media by the mapping employed by the storage system. Unusable block data marks those excess logical blocks as unusable. This makes it easy to adjust the data storage capacity of the storage system by changing the mapping to map more or less logical block addresses to space in the physical storage media and thereby destroy or create excess logical blocks, and by changing the unusable block data to correspondingly change the excess logical blocks marked as unusable.
