Abstract

The invention discloses a storage cluster and service data maintenance method and device and a computer readable storage medium, the method is applied to each storage node in the storage cluster, andeach storage node operates a network attached storage service based on a deployed CTDB. The method comprises the following steps: calling a network card monitoring service preset in the CTDB so as toperiodically detect the network state of the storage node, if the network of the storage node is abnormal, generating a kill command based on the CTDB to terminate the residual process of the networkattached storage service running on the storage node so as to remove the currently cached service data, continuing to call the network card monitoring service to periodically detect the network stateof the storage node, and after the network of the storage node is recovered, restarting the network attached storage service on the storage node. According to the method and the device, the problem ofdata inconsistency of the storage nodes due to the cache data of the residual process is effectively avoided, so that the data storage reliability of the storage cluster is improved.

Description

technical field [0001] The present application relates to the technical field of cluster storage, and in particular to a maintenance method, device and computer-readable storage medium for storing cluster and business data. Background technique [0002] In today's society, with the rise of cloud computing and big data, the amount of data generated every day is increasing exponentially; traditional storage can no longer meet the demand, and distributed mass storage that supports dynamic capacity expansion has emerged as the times require. [0003] CTDB (Cluster Trivial Database, database cluster) is a lightweight cluster database implementation. It is a cluster database component of cluster Samba, and is often used to process cross-node messages of Samba. CTDB is a distributed TDB database implemented on cluster nodes, which can be effectively used to ensure high availability of storage services, and in particular, can be specifically applied to network attached storage servi...
