Problems solved by technology

First of all, even if the backup frequency is high, it is still unavoidable that the system configuration may be changed between two backups
In particular, operations such as adding or reducing storage units, changing client authorization information, etc., the restored information is different from the real information, which will affect the normal operation of the system
Secondly, even if no information is lost, it still takes a long time to rebuild a management node, which is obviously unacceptable for those systems with large scale, many users, and frequent management operations
Using shared disk array can solve the above problems, but the cost of shared disk array is too high

Embodiment Construction

[0029] Specific embodiments of the present invention will be further described in detail below.

[0030] The present invention aims to realize the high availability of Parastor200 management nodes. By analyzing the problems existing in the prior art, we know that the present invention is to solve the following two problems: (1) synchronization of management node storage system information; (2) management node failover.

[0031] To solve the synchronization of management node storage system information files, it is to realize that when any changes occur in the storage information files of the management node, the storage system information files in the corresponding directory of the standby management node also change at the same time, and the information in the corresponding directories of the active and standby nodes is completely consistent. This patent uses distributed block devices to solve this problem. Distributed Block Device is a software-implemented, shared-nothing, ...

Abstract

The present invention relates to a high-availability method for Parastor200 management nodes based on distributed block devices. The method is realized through the following two aspects: (1) synchronization of management node storage system information; (2) management node failover. The present invention enables the Parastor200 to realize a fully redundant design in a complete sense by realizing the high availability of the Parastor200 management node, and the damage of any part in the system does not affect the use of the storage system. If any part of the management node is damaged, the service can be switched to the standby node within seconds. This will not affect the normal use, and there is enough time to repair the fault.

Description

technical field [0001] The invention relates to a high-availability method of a Parastor200 parallel storage management node based on a distributed block device. Background technique [0002] The ParaStor200 parallel storage system adopts a parallel architecture representing the development direction of storage technology, network communication technology and data management technology. It is a high-end storage system with independent intellectual property rights for massive unstructured data processing. It can provide TB / s-level high-speed bandwidth and EB-level massive storage space, which can meet the requirements of aircraft, automobile and ship design, biological gene research, material science research, weather forecast, earthquake monitoring, environmental monitoring and analysis, energy exploration, e-commerce, network Applications that require extremely high storage capacity and I / O performance in the fields of games, social networking and video sharing website cons...
