Abstract
Embodiments of the present disclosure relate to a method, an electronic device, and a computer program product for storage management. The method for storage management includes determining the data volume of corresponding failed data in a plurality of candidate sub-storage spaces of a disk, the plurality of candidate sub-storage spaces being formed by dividing the original storage space of the disk and having consecutive physical addresses, and the size of one candidate sub-storage space being associated with the size of the storage space of at least one block that constitutes the disk; and selecting a target sub-storage space to be released from the plurality of candidate sub-storage spaces based at least on the data volume of the corresponding failed data. As such, since the operation of moving valid data in an SSD block to a new SSD block is reduced, the WAF of a storage system, especially an SSD, can be effectively reduced, and the service life of the SSD can be prolonged.
