Embodiment approach

[0164] As an implementation manner of the embodiment of the present invention, the method may also include:

[0165] regularly send the system time of the storage server itself to the management server, so that the management server can obtain the standard time according to the system time of each storage server at regular intervals, wherein the standard time is after the system time of each storage server is synchronized time.

[0166] As an implementation manner of the embodiment of the present invention, the system time of the storage server is synchronized with the system time of the NTP server through NTP.

[0167] In the embodiment of the present invention, the system time of each storage server can be synchronized with the system time of the NTP server through NTP, and the synchronization method is the same as the synchronization method mentioned above, which will not be repeated here.

Abstract

The embodiment of the invention provides a data deletion method and a distributed storage system, and a method applied to a management server in the distributed storage system, and the method comprises the steps of determining a target time point according to a preset data deletion rule when it is determined that data needs to be deleted in batches; and sending the determined target time point toa storage server, so that the storage server receiving the target time point deletes the to-be-deleted data according to the target time point, and the to-be-deleted data is the stored data of which the storage time is before the target time point. By applying the data deletion method provided by the embodiment of the invention, the storage space release efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data deletion method and a distributed storage system. Background technique [0002] A distributed storage system is a system in which different servers are interconnected through a network and work together to provide users with massive data storage capabilities. The distributed storage system mainly includes: a management server and a storage server, and the index information of the data stored by the management server. The index information of the data includes information such as the size, storage time, and storage location of the data. In the case of data block storage, The index information of the data also includes the index information of the data blocks corresponding to the data; for example, the management server may be a metadata server ((MetadataServer, MDS) in the object storage system; the storage server is mainly used to store data, for example Specifica...
