Problems solved by technology

The mass storage space of the distributed file system is constructed through the storage devices at the back end of the data node cluster. In a data node cluster with a certain number of nodes, it is a frequent phenomenon that the data storage volume cannot be accessed due to node failure. By mapping the data storage volume to The physical addresses of all data nodes and the introduction of high-avail

Embodiment Construction

[0016] The method of the present invention is described in detail below with reference to the accompanying drawings.

[0017] The content of the present invention is based on the construction of a distributed file system. By establishing a virtual address pool on the data node (sub) cluster, the virtual IP address in the pool is dynamically allocated and migrated in the data node sub cluster; the backend of the data node (sub) cluster The data storage volume is mapped to all virtual IP addresses in the virtual address pool, so that the mounting of the data storage volume no longer depends on the physical address of the data node, and when any data node fails or the load is high, the data storage volume can be migrated to Any node in the sub-cluster, and the network-related parameters of the replacement node do not have to be the same as the network parameters of the faulty node; by deploying the monitoring module on all data nodes in the data node (sub-) cluster, the running st...

Abstract

The invention provides a distributed file system data volume deployment method based on a virtual address pool. A node cluster or a sub-cluster is built according to different node roles of metadata nodes, data storage nodes and client side nodes in a distributed file system; a data storage volume is deployed in a mode based on the virtual IP address pool on a data node cluster to separate the deployment of a distributed file system data storage volume from physical addresses of data nodes so as to combine the deployment of the data storage volume with virtual addresses of the data node cluster; a monitoring module is deployed on an operating node of the distributed file system so as to realize real-time monitoring of the operating conditions of the node and a load; according to the conditions of the node and the load, a virtual IP borne by any node and the data storage volume mounted on one virtual address are transferred in real time in the data node cluster; meanwhile, a failure of a physical node is also isolated, so that the effect that data services of the data storage volume are not interrupted when the physical node is maintained is ensured.

Description

technical field [0001] The invention relates to the field of distributed file systems applied in the fields of cloud computing and cloud storage, and in particular to a method for deploying data volumes of a distributed file system based on a virtual address pool. Background technique [0002] With the further development of cloud computing technology and cloud storage technology application, the distributed file system as the core of its application has been rapidly applied and developed. Because cloud computing and cloud storage applications carry features such as scalable and massive storage content, the existing stand-alone file systems cannot meet the storage requirements of cloud-related services due to their limited capacity and lack of real-time scalability. ; Therefore, a distributed file system with dynamic high scalability, cluster architecture, support for high concurrency, and large capacity has become the choice of cloud computing business back-end storage devi...
