Method and device for setting osd heartbeat mechanism of distributed file system

Abstract

The invention discloses an OSD heartbeat mechanism setting method and device of a distributed file system, and a computer-readable storage medium. The method includes: a first node assembles a heartbeat message according to state information of all its own OSDs at a preset time interval, and Send the heartbeat message to the corresponding receiving node; each receiving node calls the heartbeat processing function of all its own OSDs according to the received heartbeat message, and updates the heartbeat related information of the OSD corresponding to the PG group information heartbeat message saved by all its own OSDs ; In the present invention, the first node assembles the heartbeat message according to the state information of all OSDs of itself according to the preset time interval, and sends the heartbeat message to the corresponding receiving node, which can be sent between nodes in single-process mode. The heartbeat message containing the status information of all OSDs on the node can reduce the number of OSD heartbeat messages, reduce system resource consumption, and improve system stability.

Description

technical field [0001] The invention relates to the field of distributed file systems, in particular to an OSD heartbeat mechanism setting method, device and computer-readable storage medium of a distributed file system. Background technique [0002] With the development of science and technology in modern society, the application of distributed file system has been paid more and more attention by people. During the operation of the distributed file system, it is necessary to respond to failures in a timely manner, so it is necessary to rely on the OSD heartbeat mechanism to detect the health of the system. [0003] In the prior art, the OSD (Object-based Storage Device, object storage device) heartbeat mechanism is a group of OSDs that send messages to each other for state detection. The sending and receiving of the OSD heartbeat mechanism can be as follows: figure 1 As shown, the OSD where a PG (collection of data object storage) is located is a heartbeat detection group,...

[0003] In the prior art, the OSD (Object-based Storage Device, object storage device) heartbeat mechanism is a group of OSDs that send messages to each other for state detection. The sending and receiving of the OSD heartbeat mechanism can be as follows: figure 1 As shown, the OSD where a PG (collection of data object storage) is located is a heartbeat detection group, and each node in the group sends heartbeat messages to each other. The scale will increase exponentially, which will not only consume system resources, but also easily lead to heartbeat timeout due to lack of system resources, which will lead to abnormal cluster status
