File system capacity expansion method and device, electronic equipment and storage medium

Abstract

The invention provides a file system capacity expansion method and device, electronic equipment and a storage medium, and relates to the technical field of data storage. The method comprises the following steps: determining whether a file system meets a capacity expansion condition or not according to the capacity of a new logic space of the file system and the size of a data block; if yes, determining a capacity expansion state value of the file system according to the utilization rate of each preset type of resource of the file system in the preset unit time period, the capacity expansion state value being used for indicating a capacity expansion mode of the file system; and according to the capacity expansion state value and the determined capacity expansion parameter, carrying out capacity expansion on the file system. In the method, when the expansion of the file system is executed, the expansion state value is determined by taking the utilization rate of the system resources as a reference factor, so that the expansion mode is determined to accurately judge whether the expansion of the file system is executed or not, normal storage and updating of data in the file system can be ensured while the expansion of the file system is performed, and the storage service performance of the file system is improved.

Description

Technical field [0001] The present application relates to the field of data storage, and in particular, there is a file system expansion method, device, electronic device, and storage medium. Background technique [0002] With the rapid development of the economy and technology, the amount of Internet data increases, and the reliability and high performance storage of data are especially critical. The software institution responsible for managing and storeing file information in the operating system is called the file management system, referred to as File system. The capacity size of the file system often determines the storage service capability of the storage system. As the amount of data is increasing, it is very important to expand the file system. [0003] In the prior art, the expansion process is performed directly according to the current capacity of the file system, when the current capacity of the file system does not satisfy the preset threshold. [0004] However, the...
