Abstract

The invention provides an expansion method and device of a lustre file system. The method comprises the following steps: determining a to-be-expanded lustre file system which comprises at least one client; creating a RAID storage pool by using at least one storage server; adding the created RAID storage pool in the lustre file system to obtain the expanded lustre file system; and mounting the expanded lustre file system on each client. Therefore, the scheme provided by the invention can expand the volume of the lustre file system.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for expanding the capacity of a lustre file system. Background technique [0002] The Luster file system is a Linux file system developed by the U.S. Department of Energy and Intel Corporation. It has the advantages of high concurrency and fast reading and writing. 90% of the world's top 500 supercomputers use this file system. [0003] The Luster file system is a cluster-oriented storage architecture that can provide massive capacity storage, high concurrency, and high read / write solutions. However, after the Luster file system is used for a period of time, the capacity and performance usually cannot meet the computing needs. Contents of the invention [0004] The invention provides a method and device for expanding the capacity of a lustre file system, which can expand the capacity of the lustre file system. [0005] In order to achieve the above objec...
