Problems solved by technology

In the prior art, when the state of the management nodes in the management cluster changes or when the management nodes in the management cluster are added or deleted, a new round of election will be triggered, because during the entire election process, the distributed storage system cannot For providing services, if the network status of one of the management nodes in the management cluster is unstable and the management node is abnormal, it will cause frequent elections of the management cluster, which will affect the normal business continuity in severe cases and reduce the reliability of the entire distributed storage system. sex

Abstract

The invention relates to the technical field of distributed storage, which provides an election request processing method and device, a management node and a storage medium. The method comprises: receiving an election version number recorded by an abnormal recovery management node sent by the abnormal recovery management node and a latest election time; when the election version number is greaterthan the local version number, whether the election request is ignored is judged according to the current system time and the last election time; when the difference between the last election time andthe current system time is less than or equal to the preset threshold, the election request is ignored. When the difference between the last election time and the current system time is greater thana preset threshold, the election request is accepted to start the election. By conditionally ignoring the election request, the invention realizes shielding and isolating of the problem management node, and reduces the election frequency of the management cluster, thereby ensuring that the management cluster can normally provide the service, and further improving the reliability of the whole distributed storage system.

Description

technical field [0001] The present invention relates to the technical field of distributed storage, in particular, to an election request processing method, device, management node and storage medium. Background technique [0002] In the distributed storage system, the management node is used to maintain the status information of the distributed storage system. Before the client reads and writes the data stored in the distributed storage system, it must first obtain the status information of the distributed storage system through the management node. For normal read and write operations, therefore, the reliability of the management node is very important for the distributed storage system. In order to avoid single point of failure, improve the reliability of the management node, and then improve the reliability of the distributed storage system, distributed In a storage system, multiple management nodes are usually formed into a management cluster, and the role of each manag...
