Method, electronic device and computer program product for managing storage space

An electronic device, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor and having instructions stored thereon, the instructions causing, when executed by the at least one processor, the device to perform actions comprising:
• determining, based on sizes of a storage space used by a file system at a set of historical moments and a current moment, a plurality of predicted sizes of a storage space to be used by the file system at a plurality of future moments;
• determining sizes of an available storage space and available durations of a set of candidate future moments in the plurality of future moments based on the plurality of predicted sizes, the available storage space being a storage space that is not used in a storage space allocated to the file system;
• determining, based on the sizes of the available storage space and the available durations of the set of candidate future moments, a plurality of predicted values that characterize available storage capacities of the set of candidate future moments;
• and
• determining a target moment from the set of candidate future moments based on the plurality of predicted values, so as to recycle at least part of an available storage space of the target moment.

A computer program product having a non-transitory computer readable medium which stores a set of instructions to manage a storage space;

• the set of instructions, when carried out by computerized circuitry, causing the computerized circuitry to perform a method of:
• determining, based on sizes of a storage space used by a file system at a set of historical moments and a current moment, a plurality of predicted sizes of a storage space to be used by the file system at a plurality of future moments;
• determining sizes of an available storage space and available durations of a set of candidate future moments in the plurality of future moments based on the plurality of predicted sizes, the available storage space being a storage space that is not used in a storage space allocated to the file system;
• determining, based on the sizes of the available storage space and the available durations of the set of candidate future moments, a plurality of predicted values that characterize available storage capacities of the set of candidate future moments;
• and
• determining a target moment from the set of candidate future moments based on the plurality of predicted values, so as to recycle at least part of an available storage space of the target moment.
