Problems solved by technology

[0004] In the process of research and development, it is inevitable to need a storage cluster environment for testing and debugging, but if you want to build a cluster with a real physical device area, it will be a very large expense, and if the cluster is very large, the entire debugging and development cycle will be exhausted. very long

Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0023] The present invention designs an implementation method of a virtual file system that simulates a cloud storage device. Based on the ext3 file system of Linux, the physical structure of its data storage is expanded, and the relevant parameters are calculated according to the parameters passed in when the file is mounted. Configure the threshold so that it is the same as a common file system within the configured threshold range when starting to write. When the configured threshold is exceeded, only metadata information is written, and data information is not written, the...

Abstract

The present invention designs an implementation method for a virtual file system of simulating a cloud storage device. The method comprises: taking an ext3 file system of Linux as a basis, extending a physical structure of data storage of the system; according to an incoming parameter when a file is mounted, calculating a relative configuration threshold to enable the ext3 file system to be the same as a common file system within a configuration threshold range when starting writing, and when the configuration threshold is exceeded, only writing metadata information and not writing data information, so as to utilize finite physical devices to simulate a huge memory capacity.

Description

technical field [0001] The invention relates to the field of NAS storage of computer clusters, in particular to a method for simulating large-scale cloud storage cluster devices by using limited storage devices. Background technique [0002] With the advent of the Internet era, a large amount of data is generated every day in all walks of life around the world, including personal data. In order to collect and manage these data, some large Internet companies or other companies that generate large amounts of data have to With the establishment of public or private data centers, the traditional storage model can no longer meet the explosive growth of data, and each enterprise building a data center will cause a huge waste of resources. Cloud storage technology came into being in this context. [0003] Cloud storage is a new concept extended and developed from the concept of cloud computing. It is an emerging network storage technology. It is a system in which various types of ...
