Abstract
A storage management technique involves: determining a spare degree of physical storage space of a file system and access characteristics of the file system; determining, using a provision operation classification model and based on the spare degree and the access characteristics, a target storage provision operation to be performed for the file system from multiple storage provision operations, wherein the multiple storage provision operations include at least a storage space expansion operation and a storage space reclamation operation, and the provision operation classification model characterizes an association relationship between different spare degrees and different access characteristics of the file system and the multiple storage provision operations; and performing the determined target storage provision operation for the file system. Accordingly, a better balance is achieved between storage efficiency and I/O performance.
