Management method and device for file system directory entry

Abstract

The invention discloses management method and device for a file system directory entry, and relates to a file system with the storage organization mode that the directory properties are embedded into a directory list. The method comprises the steps of receiving a first operation request from a client, wherein the first operation request is used for creating a file in the directory of the file system; creating the file in the directory, and distributing a file identity to the file; inserting the file name and property information of the file into a directory storage object corresponding to the directory; determining that the file name and property information of the file are inserted, sending a response message of the first operation request to the client, wherein the response message includes a directory entry handle corresponding to the directory; the directory entry handle includes the file identity and the identity of the directory storage object. With the adoption of the method and device, the problem of large delay of operation response in file creation in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and device for managing directory items in a file system. Background technique [0002] A file system is a system for managing files and directories. Files and directories are collectively called directory entries, and these directory entries form a file system directory tree. When a user creates a new directory item, the file system will assign a file and directory unique identifier (file identity, fid) as the unique identifier of the directory item; when the user accesses a directory item specified by a certain path, the file system starts from the root directory and Level search resolves the directory item name, and finally obtains the attribute information of the last level directory item. This process is called forward indexing. [0003] However, in some scenarios, it is necessary to reversely obtain information about the path of the corresponding directory item thro...
