Problems solved by technology

However, the manual disk removal method is suitable for clusters with a small number of nodes and disks. When the number of nodes and disks in the cluster increases, the manual disk removal method requires a lot of manpower and low test efficiency.
In addition, when the number of nodes and disks is large, the number of test cases will increase accordingly, and manual operation may cause omission or confusion of test cases, which affects the accuracy of the test

Abstract

The invention provides an OSD (object-based storage device) disk fault testing method applied to a distributed file system. The OSD disk fault testing method includes: after receiving a fault testing order, determining a testing script type according to a redundancy rule of a data pool of the distributed file system; according to the testing script type, determining test cases respectively corresponding to nodes in the distribute file system and fault scripts in one-to-one correspondence with the test cases, wherein the fault scripts include orders for simulative plugging-out and simulative insertion of OSD disks; according to names of the nodes and IDs (identifications) of the OSD disks, realizing fault testing by executing corresponding fault scripts on the OSD disk on every node until all the test cases corresponding to the nodes are used completely. The OSD disk fault testing method has the remarkable advantages that the amount of labor is decreased, testing efficiency is improved, and cover degree and accuracy of are increased. The invention further provides an OSD disk fault testing system having the same advantages.

Description

technical field [0001] The invention relates to the field of data storage systems, in particular to an OSD disk failure testing method. The invention also relates to an OSD disk failure testing system. Background technique [0002] In a distributed file system, data is scattered and stored on OSD (Object-based Storage Device, object storage) disks of cluster nodes according to specified redundancy rules. In practical applications, a node usually has 12 to 36 disks. Compared with other hardware, the probability of disk failure is significantly higher. The distributed file system allows one or more disk failures of cluster nodes within the scope of the specified redundancy rules, but it must ensure that the cluster can be used normally without data loss. Therefore, it is very important to perform OSD disk failure testing during product development. important. [0003] In the prior art, a certain or some OSD disks are usually manually pulled out, and then it is judged whethe...
