Embodiment Construction

[0019] A metadata cluster design method based on a real-time application cluster of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] as attached figure 1 As shown, the present invention proposes a metadata cluster design method based on a real-time application cluster, and its specific design process is as follows:

[0021] one, Initial deployment: First, perform the initial configuration of the metadata cluster, which consists of several metadata nodes to form a metadata cluster, generate configuration files and synchronize them to each metadata node, and complete the initialization of metadata storage on each metadata node; when starting the cluster Start each metadata node sequentially, and the metadata node with the smallest number in the configuration file automatically obtains the leadership, and guides the entire metadata cluster to establish a globally consistent cache and shared lock.

[0022] 2. Fault ...

Abstract

The invention provides a metadata group design method based on a real-time application group. The particular design process comprises the step of initial deployment, wherein initial configuration is carried out on a metadata group, the metadata group is composed of a plurality of metadata nodes, a configuration file is generated and synchronized to each metadata node, and the initialization of metadata storage is finished on each metadata node; the step of sequentially starting each metadata node when the group is started, wherein the metadata node with the smallest number in the configuration file automatically obtains the hegemony and guides the whole metadata group to build an overall consistency buffering and sharing lock; the step of fault recovery; and the step of adding new metadata nodes. Compared with the prior art, the metadata group design method based on the real-time application group achieves transverse expansion of the metadata group in a group file system, effectively resolves the performance bottleneck of metadata in a large-scale group file system, is high in practicability and is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of computer clusters, in particular to a metadata cluster design method based on real-time application clusters. Background technique [0002] With the rapid development of network applications, the amount of network information data is increasing, and PB-level mass data storage is becoming more and more important. The traditional file system can no longer meet the requirements of large capacity, high reliability, and high performance of existing applications. In order to meet these new requirements, the application of new cluster storage systems has been widely valued. [0003] In traditional cluster file systems, metadata performance often becomes the performance bottleneck of the system. Early cluster file systems have one and only one metadata node responsible for metadata storage, access and processing. In a more advanced cluster file system, there are multiple metadata nodes providing services at the...
