Embodiment Construction

[0034] refer to Figure 1-12 . The specific steps of the method for realizing the automatic streamlining of the storage system in the present invention are as follows:

[0035] The used system of the inventive method comprises: (1) file system metadata management module; (2) IO reading and writing monitoring module, wherein IO refers to Input / Output, input and output; (3) storage space monitoring module; (4) A file system scaling adjustment module; (5) a storage space scaling adjustment module. The functions of each part are as follows:

[0036] The file system metadata management module provides file and storage device metadata organization forms;

[0037] The IO read and write monitoring module monitors the IO read and write requests, searches for available blocks and stores data according to the metadata information provided in the file system metadata management module;

[0038] The storage space monitoring module monitors the space usage. If the space usage reaches a ...

Abstract

The invention discloses a method for realizing thin provisioning of a storage system, and aims to solve the technical problem of poor practicability in an existing thin provisioning method for the storage system. According to the technical scheme, a user and a manager of uniform resources ensure on-demand allocation of data storage by adding control information into file system metadata, and ensure that data is not stored in any unallocated space. In combination with an API (Application Program Interface) provided by a cloud storage system, expansion and use of an online storage space are realized, and the aim of thin provisioning is fulfilled. File system metadata information is redefined to include equipment information and address mapping information; a logical space is partitioned into allocated spaces and unallocated spaces in a file system, and address mapping management is performed; and a read-write process is monitored, so that read-write operation does not access the unallocated spaces. Through the method, the storage space can be managed conveniently; dynamic extension and retraction of the storage space are realized; and the practicability is high.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a method for realizing automatic compaction of a storage system. Background technique [0002] Thin provisioning is a capacity allocation technology. It does not allocate storage space to applications at one time, but gradually increases the storage space allocated to applications according to the growth of application requirements. Traditional thin provisioning techniques provide large-capacity virtual drives to the operating system. The actual capacity of the virtual drive is not large, but the virtual drive reports to the operating system that it has a larger capacity. The operating system can format a larger-capacity file system on the virtual drive. In a thin-provisioned storage system, physical resources need to be increased only when capacity increases. This method delays the deployment time of physical resources and improves equipment utilization. [000...
