Embodiment Construction

[0012] The DNS service configuration is introduced into the cluster storage system based on CTDB, and the DNS service is used to resolve the same domain name into external virtual IP addresses of multiple conversion nodes in turn, and the client uses the domain name to access the storage system. load balancing.

[0013] The selection of the DNS master-slave server depends on the application environment. Simply speaking, it can be divided into the following two situations:

[0014] (1) There are external DNS master-slave servers available

[0015] This is the ideal situation, perform the following steps:

[0016] a) On the main DNS server, resolve the same domain name to the virtual IP address between conversion nodes provided by CTDB service;

[0017] b) Set the DNS master and slave server addresses of all clients to the IP addresses of the external master and slave servers respectively;

[0018] However, there is more another situation in the actual application scenari...

Abstract

The invention provides a method for converting load balancing among nodes in a cluster storage system, and relates to the field of distributed cluster storage systems. DNS service configuration is introduced into the cluster storage system achieved based on CTDB, the same domain name is analyzed into virtual IPs provided for the outside by the CTDB in sequence, automatic load balancing is achieved through an IP load balancing mechanism of a DNS, and therefore when a client side has access to the storage system through the domain name, the problem that due to the fact that too many client sides have access to the same IP address at the same time under a simple IP address access mode, the load of the single node is too large can be solved, the resources of various conversion nodes can be used in a balancing mode, and DNS service single node failures are eliminated from the configuration of the server by the DNS.

Description

[0001] technical field [0002] The invention relates to the field of distributed cluster storage systems, in particular to a load balancing method among switching nodes in the cluster storage system. Background technique [0003] For the conversion nodes in the cluster storage system that provide external file access functions, the CTDB (Clustering TDB) service configuration can be constructed based on the Glusterfs cluster shared storage to realize the IP Takeover between them, which is what we often call the IP high availability mechanism, so that one or When some conversion nodes fail, customers can still use the original IP address for file access. [0004] However, the actual project application shows that in the IP address access mode of the conversion node, the access to one or some IP addresses largely depends on the user's habit of using the IP address; the client request received by each conversion node Load balancing can only be controlled manually, and there...
