Metadata performance optimization method and system based on system disk sharing

Abstract

The embodiment of the invention discloses a metadata performance optimization method and a metadata performance optimization system based on system disk sharing, which are applied to a video monitoring scene, and comprise the following steps of automatically filling a node OS on a system disk, and reserving a GPT partition on the system disk as a metadata partition; traversing all drive charactersin a video monitoring scene, and identifying whether a system drive is an SSD or not; if the system disk is the SSD, deploying metadata on the metadata partition, and if the system disk is not the SSD, deploying the metadata on the data disk; and automatically separating metadata. In the invention, after a node OS is automatically filled on an SSD system disk, the partitions of the SSD system disk serve as metadata pools, metadata services are deployed on the system disk to be specially used as a video monitoring scene, and due to the fact that the read-write performance of the SSD is much higher than that of a mechanical disk, the metadata are deployed on the system disk, the requirement for cost can be met, and the read-write performance of the metadata can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of metadata performance optimization, in particular to a metadata performance optimization method and system based on system disk sharing. Background technique [0002] With the rapid development of information technology, more data needs to be stored. The data in the distributed storage system is divided into data and metadata. Data refers to the actual data in ordinary files, while metadata refers to the metadata information in the distributed storage file system. It belongs to hot data and is generally stored on high-speed devices. . [0003] In video surveillance scenarios, only mechanical disks are configured for data disks, and metadata is deployed to mechanical disks. 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. Therefore, the performance of manipulating files is limited by ...

Problems solved by technology

[0005] The embodiment of the present invention provides a metadata performance optimization method and system based on system disk sharing, which is applied to video surveillance scenarios. After the node OS is automatically filled on the system disk, metadata partitions are reserved, and the system disk is identified as SSD, the metadata is deployed on the metadata partition to solve the problem of poor performance of the metadata disk caused by the metadata being deployed to the mechanical disk in the prior art
