Node processing method, device and equipment based on distributed storage system and medium

Abstract

The invention discloses a node processing method and device based on a distributed storage system, electronic equipment and a computer readable storage medium, and the method comprises the steps thata main node sets a detection program, and reduces the process priority of the detection program to a preset detection priority; after the detection program is started, obtaining false dead node mark information of a false dead node by utilizing the detection program; and deleting the false dead node from the detection queue according to the false dead node marking information, and sending storageservice information of the false dead node to the monitor, so that the monitor stops the storage service of the false dead node. According to the invention, the detection program is set and the priority of the detection program is reduced; when the node is falsely dead, the detection program cannot normally run; and the main node obtains the false dead node mark information of the false dead nodeby using the detection program, monitors the storage service of the false dead node in real time, and can determine the false dead node and delete the false dead node from the detection queue, so thatthe monitor stops the storage service of the false dead node, and the storage service of the false dead node is offline.

Description

technical field [0001] The present application relates to the technical field of distributed storage systems, and in particular to a node processing method based on a distributed storage system, a node processing device based on a distributed storage system, electronic equipment, and a computer-readable storage medium. Background technique [0002] As one of the core elements of data resources, data storage has also ushered in a period of rapid development. Traditional network storage systems use centralized storage servers to store all data. Storage servers become the bottleneck of system performance and the focus of reliability and security, which cannot meet the needs of large-scale storage applications. The distributed network storage system adopts an expandable system structure, which not only improves the reliability, availability and access efficiency of the system, but also is easy to expand, thus being accepted and recognized by more and more enterprise units.

SSHD is to participate in process scheduling, but the priority is not as high as the Killer process of the OOM mechanism.

In this way, it will not be scheduled by the system all the time, so that it will not be able to provide services correctly to establish a new connection with the SSH client

[0004] When the server freezes, the response of the storage service on the server is very slow. At this time, the heartbeat of the storage service cannot detect that the storage service on the node is unavailable in time, which makes the read and write performance of the entire storage cluster very low, seriously affecting the front end. business
