Abstract
Storage blocks are managed. For instance, a set of write parameters and a set of deletion parameters are obtained related to a target storage block. In response to the set of write parameters matching the set of deletion parameters, a first data length is obtained for the target storage block, the first data length being determined in response to receiving a write request for the target storage block. Further, reclaim information is determined related to the target storage block based on the first data length and the set of deletion parameters. It is thus possible to reduce times of scanning the entire object table to determine whether there is an object referring to the storage block, thereby reducing the time consumed by the verification process and improving the reclaiming speed of storage blocks.
