Problems solved by technology

In fact, the data deletion operation needs to occupy the bandwidth of the disk, and will preempt other read and write request resources of the user. If it is executed during the data migration process, it will make the system under greater pressure due to the data migration to bear more pressure

Abstract

The invention provides a data deletion method and system for a distributed storage cluster comprising following steps: data to be deleted corresponding to a data deletion request is distributed to a list to be deleted according to the data deletion request; whether a data deletion operation of the disk based on a list to be deleted according to at least a data migration state of a disk in the distributed storage cluster is performed or not is determined. The invention also provides a corresponding system. Because of the pressure on the disk when data migration occurs in the disk, the embodiment of the present invention can at least delete the data to be deleted when the disk does not have data migration; Compared with the prior art, it is possible to avoid deleting data when the disk pressure is large, to reduce the system load of the special period, to avoid the situation that the system performance is degraded due to preempting the disk resource with other read and write requests, and to realize the stable operation of the system. And the process of avoiding large disk pressure to delete the data is automatic without human action to enhance the user experience.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data deletion method and system for distributed storage clusters. Background technique [0002] The distributed storage system is to divide the data according to certain rules and store them scatteredly on multiple independent general-purpose storage servers. Traditional network storage systems use centralized storage servers to store all data. Storage servers become the bottleneck of system performance and the focus of reliability and security, which cannot meet the needs of large-scale storage applications. Distributed storage systems use scalable systems Structure, using multiple storage servers to share the storage load, using the location server to locate the storage information, it not only improves the reliability, availability and access efficiency of the system, but also is easy to expand. Thousands of servers in the storage cluster can make data fully redundant, wh...
