Abstract
A method for garbage collection for a storage system in an illustrative embodiment includes determining input/output (IO) access popularity of a plurality of partially occupied unit blocks in response to receiving an instruction for garbage collection for the storage system. The method further includes selecting two unit blocks from the plurality of partially occupied unit blocks based on the utilization and the IO access popularity of the plurality of partially occupied unit blocks. In addition, the method further includes determining to fully release the two unit blocks or to partially release the two unit blocks based on the two unit blocks and a target block. In this manner, by considering the IO access popularity of the unit blocks, the less active unit blocks are merged as preferentially as possible, which reduces the probability of fragment jitter, thereby improving the efficiency of garbage collection.
