Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] In the prior art, although the application of the thin provisioning technology has improved the utilization rate of the storage space, there is still idle storage space in the storage space; and the present invention effectively identifies the idle space and reclaims the idle storage space, which can further Improves storage space utilization in thin-provisioned host file systems.

[0040] The embodiment of the present invention discloses a method for r...

Abstract

The present application discloses a method for reclaiming storage space, which is applied to a host file system of a self-thin configuration, including: obtaining idle storage space in a disk block according to metadata of the host file system; judging whether the idle storage space meets the recovery requirements, If yes, reclaim the idle storage space; wherein, the reclaim requirement includes that the size of the idle storage space exceeds a preset threshold. This application is applied to a system of self-thin provisioning, uses metadata to effectively identify and obtain idle storage space, and then reclaims the idle storage space that meets the recovery requirements, further improving the utilization rate of the storage space. Correspondingly, the present application also discloses a storage space reclamation system, device and readable storage medium.

Description

technical field [0001] The invention relates to the field of self-thin configuration, in particular to a storage space recovery method, system, device and readable storage medium. Background technique [0002] With the rapid development of cloud computing, mobile Internet, Internet of Things and other technologies, massive data is growing exponentially, and the IT market has entered the era of big data. Massive data and data mining have become new opportunities and gold mines for enterprises, which put forward higher requirements for enterprise data centers and storage planning, as well as storage systems. In order to reduce upgrade and operation and maintenance costs, improve storage space utilization, and protect customers' initial investment, the storage virtualization system introduces self-thin provisioning. The self-thin provisioning technology allocates on demand and allocates as it is written, which can maximize the use of storage space and solve the problem of low ...
