Abstract:
A method of operating a storage system includes moving a block of data stored in the storage system to a new location in the storage system, such as for purposes of defragmentation. After the block has been moved to the new location, the storage system receives a request requiring access to the block. The storage system uses metadata appended to an identified block to detect that the block may have been relocated. The metadata can further be used to distinguish a block that has been relocated from a lost write.
