Abstract

The invention discloses a fault processing method, device and electronic equipment of a distributed storage system. Wherein, the method includes: when it is determined that a network failure occurs between target data centers, using a preset data placement process OSD in the target data center to detect whether a regional level failure occurs; The faulty fault domain is partitioned to obtain multiple network partitions; the target network partitions that meet the preset filtering conditions are obtained from the multiple network partitions, and the non-target network partition is determined as the faulty network partition; The disk process OSD is switched so that the distributed storage system can access services normally, and the OSD of the data disk process in the faulty network partition is controlled to stop accessing services. The invention solves the technical problems in the related art that the distributed storage dual-active system competes with each other for shared resources when a split-brain occurs, which easily leads to system confusion and unusable services.

Description

technical field [0001] The present invention relates to the field of distributed storage systems, and in particular, to a fault processing method and device for a distributed storage system, and electronic equipment. Background technique [0002] In the related art, for a distributed storage system, especially an active-active storage system, when the "heartbeat line" connecting two nodes (or data centers) is disconnected (that is, when the two nodes or data centers are disconnected), the original As an overall, action-coordinated active-active system, it is split into two independent systems. Because they lost contact with each other, they thought it was the other party's fault. The active-active software on the two systems, like "split-brain people", "instinctively" competed for "shared resources" and "application services". There are more serious drawbacks: 1) or the shared resources are divided up, and the "services" on both sides cannot be started; 2) or the "services"...
