Problems solved by technology

[0004] It can only restore the abnormal operation of the software of the faulty machine. It can be restored by automatic restart. Only its own host can be restored, and other hosts cannot be restored.
In addition, the system disk (including SSD, DOM disk, EMMC, FLASH and other power-off non-volatile storage media) is physically damaged, its working life expires, or the contents of the system disk are damaged by malicious attacks. The restart method is irreversible and has great limitations. It lacks security and stability.
[0005] Aiming at the problem that the automatic restart method in the related technology can only restore the abnormal operation of the software, no solution has been proposed

Abstract

The invention provides a cluster system exception recovery processing method and device. The method comprises the following steps: switching the state of standby equipment from a ready state to a working state when the abnormality of main equipment is detected; dividing a preset global system disk to the main equipment; and controlling the main equipment to recover from the internal system disk, or controlling the main equipment to recover from the global system disk under the condition that the main equipment fails to recover from the internal system disk. The problem of recovery through an automatic restart mode in related technologies can be solved; the problem that software operation abnormity can only be recovered is solved; the system disk can be automatically recovered when the system disk is physically damaged, expired in service life or maliciously attacked and damaged, and global recovery can be performed when any working machine in the cluster system is abnormal, so that thesafety and availability of each working machine in the cluster system are greatly improved, and long-term stable operation can be ensured.

Description

technical field [0001] The present invention relates to the field of security systems, in particular to a method and device for processing cluster system abnormality recovery. Background technique [0002] With the development of storage technology, most storage systems use multiple storage controllers to form a storage controller cluster to improve the performance and stability of the storage system. When a controller node in the cluster fails, other nodes can take over. The work of the controller keeps the overall system working, so as to ensure that the reading / writing (Input / Output, referred to as I / O for short) is not interrupted. Moreover, when the faulty controller is replaced or repaired and then added to the cluster, the cluster can automatically restore the controller node to be consistent with other controllers and resume normal work. [0003] In the related technology, it is proposed that if one or more storage systems in the cluster system are detected to be ru...
