Abstract
Techniques for managing storage blocks involve: according to a first request for allocating a target number of consecutive storage blocks from a storage device, querying an index table that is used to record index information of a plurality of groups of consecutive idle storage blocks in the storage device to determine a first group of consecutive idle storage blocks from the plurality of groups of consecutive idle storage blocks; allocating the target number of consecutive storage blocks from the first group of consecutive idle storage blocks; updating a bitmap that is used to record states of a plurality of storage blocks in the storage device; and updating first index information of the first group of consecutive idle storage blocks recorded in the index table. Accordingly, such techniques may reduce storage complexity and improve system performance.
