System for testing file system capacity based on virtualization and method thereof

Abstract

The invention relates to a system for testing file system capacity based on virtualization and a method thereof. The system comprises a capacity testing managing module, a virtual storage module, a physical storage module and a mapping managing module, wherein the capacity testing managing module is used for establishing the virtual storage module for testing the file system capacity under the tested file system, and managing the file system to create, read and delete files on the virtual storage module; the virtual storage module is used for virtually storing the file written in by the capacity testing managing module; the physical storage module is used for actually storing the file written in the virtual storage module by the capacity testing managing module; and the mapping managing module is used for dynamically managing the mapping from the virtual storage module to the physical storage module in an operation system block device drive layer, and directly mapping the file operation of the virtual storage module into the file operation to the storage unit of the physical storage module so as to guarantee that the virtualized virtual storage module can be normally read and written, thereby effectively testing the file system capacity.

Description

technical field [0001] The present invention relates to a test system and method, in particular to a test system and method based on virtualized file system capacity. Background technique [0002] In order to store the ever-increasing mass of information data, research institutions at home and abroad have proposed a variety of stand-alone or distributed file systems, such as ext3 (full name is Third extended file system), Lustre (evolved from Linux and Clusters, is for A new file system designed to solve the problem of mass storage), etc. The maximum capacity supported by these file systems is different. For example, ext3 supports a maximum of 8TB (full name TeraByte, terabyte), while Luster theoretically supports at least 64PB (full name PetaByte) space. Although the current development of disk arrays has already exceeded the limit of TB level, in general, there are still various factors such as technology and cost to reach the PB level. Therefore, when testing the capaci...

Problems solved by technology

[0004] For this reason, what the present invention is to solve is the technical problem that existing storage device virtualization tools cannot virtualize storage devices capable of normal reading and writing, and provides a virtualization-based file system capacity test that can perform normal reading and writing of data systems and methods
