Embodiment Construction

[0052]In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0053] In a distributed data storage system, different files are stored on different nodes or the same file is divided into multiple parts and stored on different nodes respectively. When accessing files, the metadata server provides the mapping relationship between data logical names and physical information , to achieve the correct positioning o...

Abstract

The invention discloses a failure diagnosis method and device of a distributed storage system. The method includes the steps: a monitoring process obtains a data operation process identification according to registration information of a data operation process to be detected, whether the data operation process corresponding to the identification exists on terminal equipment, and if the data operation process does not exist, the fact that failures occur to the data operation process is confirmed. According to the method and device, the independent monitor process is used for monitoring the data operation process, when the data operation process does not exist, the fact that the failures occur to the data operation process is confirmed, accordingly following failure processing can be triggered, failure discovery time is shortened, and failure diagnosis efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of distributed system data processing, and in particular to a fault diagnosis method and device for a distributed storage system. Background technique [0002] Traditional network storage systems use centralized storage servers to store all data, but the storage space of centralized storage servers is limited, which cannot meet the needs of large-scale storage applications. The distributed network storage system adopts a scalable system structure, dispersely stores data on multiple independent devices, and utilizes the limitation of multiple storage servers to dispersely store data, providing a solution for large-scale data storage. However, in a distributed storage system, when the process of running data (data running process) fails, if the fault cannot be detected in time and the running data is migrated to other devices, the service will stop and the service availability will be poor.
