Problems solved by technology

In practical applications, the communication traffic of the heartbeat mechanism accounts for more than 25% of the business traffic of the entire system, which limits the efficiency of other communication services in the system, that is, the heartbeat mechanism limits the concurrent processing performance of the system

Embodiment 1

[0042] Please refer to figure 1 , figure 1 It is a flow chart of a method for implementing a one-way heartbeat mechanism in an embodiment of the present invention. The method uses the TCP communication protocol to communicate, and includes the following steps:

[0043] S101. When the first node in the storage cluster receives a ping message regularly sent by the second node according to a preset heartbeat frequency, record a heartbeat time stamp corresponding to the ping message.

[0044] In this embodiment, the first node and the second node may respectively correspond to different servers in the storage cluster, and the first node and the second node may also be different storage disks or hard disks under the same server in the storage cluster. In addition, the first node and the second node are only used for different descriptions, and there is no substantial difference. In this embodiment, it is described that the second node sends a ping message to the first node. In pr...

Embodiment 2

[0057] Please refer to figure 2 , figure 2 It is a flowchart of another one-way heartbeat mechanism implementation method in the embodiment of the present invention. The method uses the TCP communication protocol to communicate, and includes the following steps:

[0058] S201. When the first node in the storage cluster receives a ping message regularly sent by the second node according to a preset heartbeat frequency, record a heartbeat time stamp corresponding to the ping message.

[0059] Wherein, the storage cluster is a ceph cluster, and the first node is a master node determined by an election mechanism in the storage cluster.

[0060] When applied to a ceph (distributed file system) cluster, the first node may be a master node determined by an election mechanism in the ceph cluster.

[0061] The election mechanism is as follows: the election mechanism ensures that there is a master node in the partition group at any time. When the master node is down, the master nod...

Abstract

The invention discloses a method for implementing a one-way heartbeat mechanism. The method performs communication by using a TCP communication protocol and comprises the steps of when a first node ina storage cluster receives a ping message sent timely by a second node according to a preset heartbeat frequency, recording a heartbeat timestamp corresponding to the ping message; calculating a timedifference between a current heartbeat timestamp and a heartbeat timestamp recorded at a previous time; judging whether the time difference is greater than a preset threshold value or not; and if yes, judging that the ping message is overtime, and sending overtime statistical information to the first node. By applying the method for implementing the one-way heartbeat mechanism provided by the embodiment of the invention, the occupation of communication resources of a storage system can be reduced, and the concurrent processing capacity of a cluster is improved. In addition, the heartbeat frequency of the heartbeat mechanism can further be doubled so that a functional module having a problem is detected more quickly. The invention further discloses an apparatus, a device and a system for implementing the one-way heartbeat mechanism, and a readable storage medium, all of which have corresponding technical effects.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a method, device, equipment, system and readable storage medium for realizing a one-way heartbeat mechanism. Background technique [0002] In a storage cluster, each storage node communicates with each other to replicate data and dynamically redistribute data. The heartbeat mechanism plays a role of keeping alive in the storage cluster, and can detect problematic functional modules in time. [0003] The existing heartbeat mechanism is a two-way heartbeat mechanism. Specifically, after the client sends a ping message to the server, it needs to receive the reply message returned by the server, and count whether the heartbeat times out by receiving the reply information. In practical applications, the communication traffic of the heartbeat mechanism accounts for more than 25% of the business traffic of the entire system, which limits the efficiency of other communica...
