Abstract

The invention provides a cloud environment distributed file system reliability test suite, and relates to the field of cloud computing. The test suite aims to solve the problems that in an existing distributed system, a suite for testing distributed file system reliability lacks, preparation for problems occurring in the distributed system can not be made in advance, and reliability of the system is low. A management module of the test suite is used for calling a corresponding node fault injection module, a data operation failure fault injection module and a data intended effect fault injection module according to operation commands of test staff, collecting fault injection results of the node fault injection module, the data operation failure fault injection module and the data intended effect fault injection module and feeding back the fault injection results to the test staff through a user main interface. The user main interface is used for being located between the test staff and the management module, providing a man-machine interaction interface, receiving commands of a user and feeding back the fault injection results. The cloud environment distributed file system reliability test suite can be used for fault injection of the cloud environment distributed file system.

Description

technical field [0001] The invention relates to a distributed file system test suite in a cloud environment. It belongs to the field of cloud computing. Background technique [0002] With the continuous development and popularization of cloud computing technology, the concept of cloud storage has emerged as the times require, and the distributed file system is the core foundation of cloud storage, carrying the heavy responsibility of data storage. On the other hand, with the improvement of the degree of social informatization, the dependence on information and data is also increasing, which means that the reliability of data is becoming more and more important. Fault tolerance is an important criterion for measuring the reliability of a system. The stronger the fault tolerance of the system, the more reliable the services it can provide. Therefore, it is of great research significance to evaluate the fault tolerance of distributed file systems in cloud environments. [00...
