Problems solved by technology

There are a lot of cluster configuration data. If the fault recovery mechanism is tested, it is not only very cumbersome but also inaccurate to manually compare whether the data before the fault and after the fault recovery meet expectations. Moreover, for different test scenarios, the verification The data information is different; the injected faults are different and the verified data are also different
The current automation tools only check all the check items for certain fault injection tests, and cannot adapt to changes in storage systems and test scenarios.
[0003] There is currently no effective solution to the problem that the test of the fault recovery mechanism in the prior art cannot adapt to changes in the storage system and test scenarios

Abstract

The invention discloses a storage fault recovery test method and device. The method comprises the steps of obtaining or generating a check item configuration file recording a plurality of check itemscorresponding to different fault recovery scenes; processing a storage cluster of the to-be-tested storage fault to obtain pre-fault check information corresponding to the execution command item, andstoring the pre-fault check information in a pre-fault list in a key value pair form; injecting a specific fault into the storage cluster, determining a corresponding fault recovery scene according tothe specific fault by using a storage fault recovery mechanism, and further recovering the availability of the storage cluster; processing a storage cluster storing fault recovery to obtain recoveredcheck information corresponding to the execution command item, and storing the recovered check information in a recovered list in a key value pair form; and determining a test result of storage faultrecovery. According to the invention, the fault recovery test can adapt to the changes of the storage system and the test scene, the test time is shortened, the manpower is saved, and the result accuracy is improved.

Description

technical field [0001] The present invention relates to the field of virtual machines, and more specifically, to a storage failure recovery testing method and device. Background technique [0002] For storage software, for the protection of system data, there is a fault recovery mechanism, and different levels of protection are applied to achieve different degrees of fault recovery, including the fault recovery level for single-node hardware or software failures, and the cluster level for cluster software failures. Restore clusters from hard disks to cope with multiple hardware failures at the same time, configuration backup and restore levels Use the backup configuration data to quickly create and configure a new cluster. There are a lot of cluster configuration data. If the fault recovery mechanism is tested, it is not only very cumbersome but also inaccurate to manually compare whether the data before the fault and after the fault recovery meet expectations. Moreover, for...
