Abstract
Techniques for wear leveling involve identifying a detected disk as a target disk in response to detecting the disk with a degree of wear greater than a first threshold in a plurality of disks of a storage array. Such techniques further involve determining, in response to the number of the target disks being greater than or equal to a second threshold, an updated weight for disk wear based on the degree of wear of the target disk and an impact attenuation factor associated with the degree of wear. Such techniques further involve performing, based on the updated weight for the disk wear, wear leveling for an input/output (IO) request on the plurality of disks in the storage array. In this way, it can effectively avoid deterioration of the storage performance caused by end of life (EOL) of too many disks at the same time point or cycle.
