Problems solved by technology

[0005] In a traditional distributed storage system, the general practice is to record the Lunmap relationship in the configuration file, and synchronize the Lunmap configuration file to different nodes through rsync+keepalived. This method cannot guarantee the consistency of the cluster configuration. , when a node fails or recovers, the cluster cannot detect it in time, and when the number of nodes in the cluster increases, this method will be difficult to meet high efficiency, high reliability and real-time performance

Abstract

The invention discloses a Lunmap management method based on ZooKeeper. The Lunmap management method based on ZooKeeper comprises the following steps that a user sends a Lunmap data request to a ZooKeeper server side through a ZooKeeper client side according to Lunmap data to be stored, and the ZooKeeper server side stores and synchronizes the data, wherein the Lunmap comprises three elements, namely Lun, Target and Initiator, and the Lun is used as a Lunmap storage main body to construct a Lunmap storage structure. The invention at least aims to significantly reduce data inconsistency in cluster management and effectively improve the storage efficiency and reliability.

Description

technical field [0001] The present application relates to the technical field of distributed storage management, and in particular, relates to a ZooKeeper-based Lunmap management method. Background technique [0002] With the rapid development of distributed technology and SAN (Storage Area Network, storage area network) storage technology, the magnitude of storage system resources has been greatly improved. However, in the face of such a huge amount of resources, how to manage them efficiently and reliably is particularly important. In order to provide users with efficient and reliable SAN services, a Lunmap management method based on ZooKeeper came into being. ZooKeeper is a distributed, open source distributed application coordination service, providing configuration maintenance, domain name service, distributed synchronization, group service and other functions. ZooKeeper guarantees the strong consistency of data in a distributed environment and can solve many distribu...
