Abstract

The embodiment of the invention provides a space recovery method, device and equipment. A plurality of storage structures corresponding to different utilization rates are set; when data is written into any data block in a plurality of data blocks in the storage system, the utilization rate of the data block is calculated, and the data block identifier of the data block is stored in the corresponding storage structure based on the utilization rate when the data block is full; and in response to the space recovery instruction, a plurality of data blocks corresponding to the at least one storage structure are selected to perform data migration according to the arrangement sequence of the utilization rates from small to large. According to the technical scheme provided by the embodiment of the invention, the recovery efficiency of the storage system in the space recovery process can be effectively improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of distributed storage, and in particular, to a space reclamation method, device, and equipment. Background technique [0002] In order to meet the storage needs of individuals and enterprises for rapidly growing data, distributed storage systems emerged as the times require. In order to improve the reliability of the distributed storage system, many enterprises use the method of appending to store data, that is, when a certain data needs to be modified, the modified data is written in a new storage location on the disk. Therefore, the data stored in the original storage location will become invalid data, and the way of appending writing will cause a large amount of invalid data in the disk, so that a large amount of storage space on the disk will be wasted. Recycle. [0003] Since the existing storage system generally divides the storage space of all the disks of the storage sy...
