Abstract

The invention provides a hot upgrade assembly and method for a GlusterFS client side. A GlusterFS client hot upgrade module is provided with: a control unit for controlling hot upgrade processing of a GlusterFS client; the first customer service unit provides customer services, the control unit creates a second customer service unit according to a latest configuration file when receiving a hot upgrade command, and performs service switching processing of the first customer service unit and the second customer service unit after performing initialization processing of the second customer service unit. And issuing the new I / O operation to the second customer service unit, waiting for returning a result of the I / O operation issued to the first customer service unit from the first customer service unit, and carrying out destruction processing on the first customer service unit under the condition that all the issued results of the I / O operation are returned from the first customer service unit.

Description

technical field [0001] The invention relates to a GlusterFS client hot upgrade component and method applied in the fields of cloud storage, distributed storage and the like. Background technique [0002] GlusterFS is a distributed file system. Compared with distributed file systems such as MooseFS, OpenAFS, and GoogleFS, GlusterFS has the advantages of high scalability, high availability, high performance, and horizontal scalability. [0003] However, in the prior art, when the program needs to be upgraded, the GlusterFS client needs to stop the client service program using its distributed file system service first, then perform the client upgrade, and then restart the client service after the upgrade is complete. . Therefore, the use of client services is severely affected during the upgrade process. SUMMARY OF THE INVENTION [0004] The present invention is completed in view of the above-mentioned problems, and proposes a GlusterFS client hot upgrade component and meth...
