Problems solved by technology

The distributed file system consists of a client, a metadata server and a data server. The metadata server has the metadata corresponding to the file stored by the data server. Metadata, also known as intermediary data and relay data, is the Data (data about data) is mainly information describing data properties (property), which is used to support functions such as indicating storage location, historical data, resource search, file recording, etc.; metadata contains the creation time of files, and the client It is necessary to display the creation time of the files downloaded from the distributed file system, but the distributed file system does not save the creation time of the files

Embodiment 1

[0062] as attached figure 1 as shown,

[0063] A method of obtaining the creation time of a file in a distributed system, comprising:

[0064] Step 100: establish a metadata virtual file system corresponding to the acquired target file through the metadata server;

[0065] Step 101: Send a target file request download command through the client, and obtain the target file in the metadata virtual file system;

[0066] Step 102: Confirm the storage information of the target file according to the metadata in the target file;

[0067] Step 103: Confirm the creation time of the target file according to the storage information of the target file;

[0068] Step 104: Display the creation time of the target file through the client screen.

[0069] The principle of the above technical solution is that the present invention sends the metadata upload command in the metadata server to the command interface by setting an upload command interface from the metadata server in the distribut...

Abstract

The present invention provides a method for obtaining the creation time of a file in a distributed system. The method includes: establishing a metadata virtual file system corresponding to a target file through a metadata server; sending a file request download command through a client, and sending a file requesting download command through a client. Obtain the target file in the metadata virtual file system; confirm the storage information of the file according to the metadata in the file; confirm the creation time of the file according to the storage information of the file; The time is displayed through the client screen. The invention solves the problem that the creation time of the file cannot be directly obtained from the distributed system.

Description

technical field [0001] The invention relates to the technical field of file processing, in particular to a method for acquiring the creation time of files in a distributed system. Background technique [0002] At present, Distributed File System (DFS) means that the physical storage resources managed by the file system are not necessarily directly connected to the local node, but are connected to the node (which can be simply understood as a computer) through a computer network; Or a complete hierarchical file system formed by combining several different logical disk partitions or volume labels. The distributed file system consists of a client, a metadata server and a data server. The metadata server stores metadata corresponding to the file in the metadata server. Metadata, also known as intermediary data and relay data, is used to describe data. Data (data about data) mainly refers to the information describing data properties (property), which is used to support function...
