Embodiment Construction

[0040] The core of the present invention is to provide a method, system, SMB client and cluster server for reconnecting clusters of SMB clients, improve the speed of reconnecting clusters of SMB clients, reduce waiting time, and make client users almost unconscious, thereby improving Continuous availability of the cluster.

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, 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 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.

Abstract

The invention discloses a cluster reconnection method for an SMB (server message block) client. The method comprises steps as follows: after a first node in an SMB file service cluster is connected, a request for returning an IP (internet protocol) address list of all cluster nodes operating RPC (remote procedure call protocol) service in the SMB file service cluster is sent to the first node; one cluster node is selected from the IP address list returned from the first node to serve as a second node; a request of connection establishment and a request of registering notification are sent to the RPC service in the second node; an RPC reply sent by the second node is received to inform that the first node is unavailable; one cluster node is selected from the IP address list to serve as a third node, a request of connection establishment is sent to the third node, and the cluster reconnection of the SMB client is realized. The speed of the cluster reconnection of the SMB client is increased, the waiting time is shortened, and the continuous availability of the cluster is improved. The invention further discloses a cluster reconnection system of the SMB client, the SMB client and a cluster server.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and system for SMB client to reconnect to a cluster, an SMB client and a cluster server. Background technique [0002] Generally, when a cluster node becomes unavailable due to some reasons, the SMB client will prompt a connection disconnection error after waiting for a certain timeout period. ) mechanism to judge whether the node is unavailable, and then give an error prompt that the connection is disconnected, which will inevitably affect the operation perception of the client user. continuous availability of the cluster. [0003] Therefore, how to increase the speed at which the SMB client reconnects to the cluster, reduce the waiting time, and make the client user almost unaware, so as to improve the continuous availability of the cluster is a technical problem to be solved by those skilled in the art. Contents of the invention [0004] The purpose of the prese...
