Abstract

Techniques for storage management involve: if it is determined that a source storage slice of a file system is to be recycled, identifying, from the source storage slice including a plurality of storage blocks, an orphan storage block that is inaccessible by a client of the file system; replicating data of the orphan storage block to a target storage block, the target storage block being located in a target storage slice within a predetermined isolation area of the file system; and generating second metadata of the target storage block based at least on first metadata of the orphan storage block, the second metadata including at least an identification of the orphan storage block. Therefore, the management performance can be improved, and the storage costs can be reduced.
