Problems solved by technology

Therefore, when the number of files is large, the number of subtree information will also increase exponentially, and the required log data will therefore become huge, which will affect the readability of the log and further affect the performance of metadata.

Abstract

The invention discloses a distributed file system subtree storage method. The method comprises the steps that a meta-data cluster conducts zoning processing on an catalogue, and a catalogue subtree is obtained; a meta-data service is distributed for information of the catalogue subtree and authority information corresponding to the catalogue subtree respectively, and the meta-data services are used as subtree information; the subtree information is stored into a meta-data pool on the basis of an SSD disk. The SSD disk is used as a magnetic disk of the meta-data, the operating property of a file system for the meta-data can be accelerated by using the quick-reading characteristic of the SSD. Due to the fact that the operating speed of a user for the file is determined by the operating speed of the meta-data, the property of the whole file system is also improved. The invention further discloses a distributed file system subtree storage device, and the device has above advantages.

Description

technical field [0001] The present application relates to the field of metadata performance optimization of a distributed file system, in particular to a method and device for storing subtrees of a distributed file system. Background technique [0002] With the rapid development of information technology, more data needs to be stored, so a file system is needed to manage the stored data. The data in the file system is divided into data and metadata. Data refers to the actual data in ordinary files, while metadata refers to the system data used to describe the characteristics of a file, such as access rights, file owners, and file storage distribution. information etc. In a cluster file system, directory information includes the location of the file on the disk and the location of the disk in the cluster. To operate a file, the user must first read the metadata of the file in order to locate the location of the file and obtain the content or related attributes of the file. ...
