Abstract

Various embodiments of the present invention provide a method and apparatus for reusing storage blocks of a file system. The file system is based on a thin-provisioned storage configuration and shares a storage pool with other file systems. The method includes detecting unused storage blocks in the storage space of the file system in response to a predefined trigger event. The method also includes providing the unused storage blocks to the storage pool for reuse in response to detecting the unused storage blocks in the storage space. According to various embodiments of the present invention, efficient utilization of storage space of a storage pool is achieved.

Description

technical field [0001] Various embodiments of the invention relate to the field of data storage, and more particularly, to methods and apparatus for reusing storage blocks of a file system. Background technique [0002] In recent years, thin provision storage configurations have been widely used because they enable users to use storage space efficiently. In a storage system using thin-provisioned storage configurations (for example, thin-provisioned LUN (Logical Unit Number) slices), one or more file systems are created based on actual storage devices with a certain storage capacity, where the created file system The total size of the set storage space may be greater than the storage capacity of the actual storage device. The storage space of the actual storage device can be regarded as a storage pool, and the created file system shares the storage pool according to the actual storage requirements. Such a configuration is beneficial to expand the actual storage device acco...
