Abstract

The invention discloses a cluster file system. The cluster file system comprises an lvm management module and an nfs management module, wherein the lvm management module creates a block device according to block device creation information and provides the block device to a cluster user so that the cluster user can directly conduct IO operation in the block device; the nfs management module mounts an nfs file system in a node which mounts an lvm storage pool, and manages the lvm storage pool through sanlock. The cluster file system provides the block device so that a virtual device can format the block device into a file system according to a file format needed by itself, and thus the procedures of the IP operation for each time are lowered; the IO operation with higher speed is provided at the same time, the efficiency of improving the cluster file system is improved, and the IO speed of the clustered virtual equipment is increased at the same time.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a cluster file system. Background technique [0002] With the rapid development of computer technology and network technology, the cluster system has gradually become the focus of the computer industry with its powerful computing power and robust fault-tolerant mechanism. However, the development of the supporting cluster file system is affected by distribution, and the development is slow. Most of the cluster file systems recreate the file system format required by the virtual machine on the basis of the original file system. This type of file system deepens the process of each IO operation and reduces the access rate of the file system. Therefore, how to improve the efficiency of the cluster file system is a technical problem to be solved by those skilled in the art. Contents of the invention [0003] The purpose of the present invention is to provide a cluster file syste...
