Abstract

The invention relates to a data deleting method, a data deleting device and a computer readable storage medium. The data deleting method is applied to the distributed storage system and comprises: receiving a data deleting request sent by a client side, and the data deleting request comprises identification information indicating a file to be deleted; storing the metadata of the file correspondingto the identification information into an object existing in a cluster mode, and returning deletion success information to the client; analyzing the file into fragmented data according to the read metadata, and deleting all the fragmented data one by one; and when all the fragmented data of the file are deleted, deleting the metadata stored in the object. According to the data deleting method, the metadata of the file to be deleted is stored in the cluster, the fragmented data are analyzed according to the metadata to be asynchronously deleted, finally, the metadata is deleted, the file can be safely and rapidly deleted, and meanwhile the deleting integrity and data consistency can be guaranteed.

Description

technical field [0001] The application belongs to the field of computer software applications, and in particular relates to a data deletion method and a data deletion device. Background technique [0002] With the rapid development of network applications, the amount of network information data is increasing, and mass data storage is becoming more and more important. The application of virtual disk technology in data security is becoming more and more common. Currently, a commonly used mapping virtual disk The way to create a disk is to create an image file and map it as a virtual disk. [0003] Compared with data storage, data reading, writing and deletion are also commonly used operations. For the client, the deletion operation is a simpler operation type than the reading and writing operation, and it should be completed quickly. In the prior art, when the client deletes the image file, it will first confirm the distribution of the fragment data that constitutes the file,...
