Problems solved by technology

However, due to the high price and poor scalability of the SAN system, it can no longer meet the requirements of thousands of CPU-scale systems.
[0007] At present, the network file system stores data on a single file server, so the file server becomes the bottleneck of system performance and the focus of reliability and security, which cannot meet the needs of large-scale storage

Abstract

The invention discloses a network file system which comprises an NFS client terminal, a server and a storage space resource pool. A Ceph client terminal, an NFS service terminal and a cluster management device are installed on the server. An RADOS block storage device logic volume is established on the storage space resource pool. An RBD logic volume is loaded on a designated catalog in the server in a hanging mode. According to the network file system, the storage space resource pool is a bottom-layer distributed storage frame which is obtained through a Ceph and the NFS service terminal in the server provides an access interface of the network file system. Namely, the network file system is the block storage frame based on the Ceph, the Ceph client terminal and the NFS service terminal server are installed and the network file system is simple, easy to use, high in reliability and easy to expand. The requirement for the storage system by a cloud platform is met.

Description

technical field [0001] The invention relates to file sharing technology, especially a network file system. Background technique [0002] Network File System (NFS, Network File System), which is used to mount the directory of the remote server file system to the directory of the local file system, allowing users or applications and other clients to access the directory structure of the remote server file system. Like accessing the directory structure of the local file system, there is no need to care about the specific types of the remote server file system and the local file system. Through the network file system, it is very convenient to realize the sharing of directories and files on different machines. [0003] Although NFS is not the only file system that implements the above-mentioned access to remote server file system functions, it is undoubtedly the most successful network file system. When the NFS client accesses the remote server file system, it needs to obtain ...
