Disk scanning method and device of file system and file management system

Abstract

The invention provides a disk scanning method and device of a file system and a file management system. The method comprises the following steps: a construction step: constructing a shared message queue which is used for storing a to-be-scanned disk directory; a starting step: starting a plurality of threads; an obtaining step: obtaining a plurality of to-be-scanned disk directories, the to-be-scanned disk directories being in one-to-one correspondence with the threads; a control step: controlling the thread to obtain file information of a file under the uppermost directory of the to-be-scanned directory or controlling the thread to return the updated to-be-scanned directory to the shared message queue; and a repeating step: repeating the obtaining step and the control step until the disk sweeping is completed. Compared with the prior art that a find tool performs single-thread disk scanning and an fd tool performs disk scanning and needs to be connected with a tool for checking file information, the disk scanning method of the file system has the advantages that disk scanning efficiency is greatly improved, disk scanning time consumption is reduced, and the problem that disk scanning methods in the prior art consume too long time is solved.

Description

technical field [0001] The present application relates to the field of software development, in particular, to a disk scanning method and device for a file system, a computer-readable storage medium, a processor, and a file management system. Background technique [0002] In the Linux system, the file system is like a tree structure, starting from a common root directory and gradually branching downwards. When a file system is very large, for example, many companies' Linux clusters often have very large and complex files. system, the number of files involved is often above tens of millions. The work that Linux cluster administrators often need to do is to scan these file systems. Scanning is to traverse all files to obtain all files in the cluster and their related information, for example, the last modification date of the file, the file Size, owner, group and other information, and then manage and make decisions based on these file information. The traditional method is ...
