Abstract

The invention discloses a fault recovery method and system applied to a pre-established storage system. The storage system comprises at least one storage node group. Each storage node group comprises M first storage nodes executing storage work and N second storage nodes not executing the storage work, wherein M and N are both positive integers. The method comprises: when any first storage node has a fault, determining that the first storage node with the fault is a faulted storage node, wherein a storage node group corresponding to faulted storage nodes is a faulted storage node group; selecting one second storage node in the faulted storage node group as a substitutive storage node according to a preset principle; and replacing the faulted storage node with the substitutive storage node, and completing the storage work that the faulted storage node needs to execute. Therefore, the workload of operation and maintenance is reduced, the recovery time of system faults is shortened, the data volume of migration is reduced, and the risk caused by system recovery is lowered.

Description

technical field [0001] The present invention relates to the field of computer technology, more specifically, to a fault recovery method and system. Background technique [0002] With the advent of the Internet era, websites for ordinary Internet users such as Weibo, WeChat, and online shopping are booming, and giant companies in the Internet industry provide various Internet-based services to hundreds of millions of users. Internet users all over the world publish information online every day, and the information data they generate is several times the amount of personal computer data. [0003] In order to cope with the surge of user requests at any time, more and more companies adopt distributed storage systems. The distributed storage system has high reliability, high availability and high scalability. It can comprehensively utilize distributed resources and transfer the load from a single storage node to multiple storage nodes, thereby improving the performance of the st...
