Abstract

The invention provides a distributed file system. The distributed file system comprises a client, a metadata node, a data node and a volume management node, wherein the client corresponds to one or more containers. The metadata node is used for storing a first corresponding relationship, the first corresponding relationship is a corresponding relationship between file system attributes and a storage position of data, and the data is actual data in a file. The data node is used for storing data. The volume management node is used for responding to a received volume creation request of the client, and creating one or more volumes, wherein each volume is an instance of a file system which can be mounted by at least one container, each file system attribute comprises an index node and corresponding index node identification information, and the index node identification information comprises a file name and any one or more of the following information: a file size, creation time, modification time, a link number, a user, a user group and a file permission. The invention further provides a computer system and a computer readable storage medium.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and more specifically, to a distributed file system, computer system and media. Background technique [0002] In the field of computer technology, virtualization (Virtualization) is a resource management technology that can abstract and convert various physical resources of a computer, such as servers, networks, memory, and storage, and present them after transformation, breaking the gap between physical structures. Indivisible barriers allow users to apply these resources in a better way than the original configuration. [0003] Container is a virtualization technology that is more efficient and lightweight than traditional virtual machines. Currently, the most popular container engine is Docker. Docker is an open source application container engine that allows developers to package their applications and dependencies into one Portable container, and then publish to any popular Linux...
