Problems solved by technology

[0002] For small and medium-sized clusters, especially small clusters, there is generally no dedicated parallel file system. Cluster computing node sharing is generally implemented through nfs. After submitting too many jobs with high IO requirements, the efficiency of the file system will be seriously reduced.

Embodiment Construction

[0018] The method of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] The Earth Observation Center of the Chinese Academy of Sciences in Beijing purchased a small cluster, a management node and 10 computing nodes, and the hard disk capacity of the computing nodes is 500G.

[0020] Luster file system implementation method:

[0021] 1. Creation of mds server

[0022] Divide a 30G partition on the management node and format it as mdt and mgs partitions;

[0023] 2. Creation of ost server

[0024] A total of 10 computing nodes, each node has 500G of disk space, take out 50G to install the operating system, and the remaining 450G space is used as the ost space of lustre;

[0025] Format the free partitions of 10 computing nodes as ost1—ost10 in sequence

[0026] So far, the luster file system has been built, consisting of 10 ost partitions with a capacity of 450G, and the file system has a total capacity of...

Abstract

The invention provides a method for expanding a parallel file system by the free hard disk space of a cluster computing node. According to the method, the goal of expanding the parallel file operation by the free hard disk space of the cluster computing node is realized through a Lustre file system, a Lustre object storage file system consists of three main parts including a client, an OST (object storage target) and an MDS (metadata server), the Lustre client operates the Lustre file system, carries out file data I / O (input / output) interaction with the OST and carries out namespace operation interaction with the MDS, i.e. the free disk space of the computing node is used as the OST of the Lustre file system and is integrated into a large file system, and then, the client of the computing node mounts the file system for use. The method for expanding the parallel file system by the free hard disk space of the cluster computing node has the advantages that the IO concurrency and bandwidth problems of the file system can be solved, in addition, the storage space of the whole cluster system can be improved, and the cluster resource is reasonably utilized.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for expanding a parallel file system by utilizing the idle hard disk space of cluster computing nodes. Background technique [0002] For small and medium-sized clusters, especially small clusters, there is generally no dedicated parallel file system. Cluster computing node sharing is generally implemented through nfs. After submitting too many jobs with high IO requirements, the efficiency of the file system will be seriously reduced. Contents of the invention [0003] The technical task of the present invention is to solve the deficiencies of the prior art, and provide a method for expanding the parallel file system by utilizing the idle hard disk space of cluster computing nodes. [0004] The technical scheme of the present invention is realized in the following manner. The parallel file operation is realized by using the idle hard disk space of cluster computing n...
