Abstract

The invention provides a method and a device for controlling the capacity of a cluster file system. Removing at least a portion of the data of the PG in the object storage device in the full capacitystate to remove the full capacity state of the object storage device; Setting the cluster file system to turn on automatic data migration to recover at least part of the deleted PG data. It can be seen that this method can guarantee the consistency of data and solve the problem of capacity overrun caused by data imbalance.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a capacity control method and device for a cluster file system. Background technique [0002] With the increasing demand for data volume, distributed storage technology has emerged as the times require, and is widely used in various fields such as video surveillance, radio and television media consulting, biotechnology, and transportation operations. [0003] Cluster File System (CFS, Cluster File System) is a kind of distributed storage technology. Multiple object storage devices (Object Storage Device, OSD) are distributed on each cluster node, and each object storage device is used to provide data services, and use the metadata server for unified management of clients and object storage devices. In the application process, with the continuous expansion of the system scale, the storage capacity of the cluster file system continues to increase. Due to the problem of data bala...
