Problems solved by technology

However, in actual application scenarios, due to the need to delete a large amount of aging data in the storage system to free up enough storage space for the storage of newly generated data, and the read and write rate of HDD is far lower than that of SSD, the storage system The data deletion efficiency is low, making it difficult to efficiently utilize the storage space of the storage system

Abstract

The present application discloses a data deletion method, which includes determining the HDD where the data to be deleted is located according to the received deletion instruction; migrating the journal and omap corresponding to the HDD to the SSD through a preset migration script; and deleting the to-be-deleted journal and omap through the SSD Deleting data; this data deletion method is based on the fact that the read and write efficiency of SSD is much higher than that of HDD. The journal and omap of data stored in HDD are migrated to SSD through a preset migration script, and the data stored in journal and omap is deleted through SSD. , which greatly improves the data deletion efficiency of the storage system, frees up storage space for new data storage more efficiently, facilitates the integration and utilization of the storage space of the system, and effectively improves the utilization rate of storage space. The present application also discloses a data deletion system, a device and a computer-readable storage medium, all of which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of storage technologies, and in particular, to a data deletion method, and also to a data deletion system, an apparatus, and a computer-readable storage medium. Background technique [0002] With the continuous development of information technology, data as a valuable resource is gradually being valued by people. As one of the core elements of data resources, data storage has also ushered in a period of rapid development. For storage systems, it can be used as a storage medium for storing data. There are various types, such as disks, hard disks, etc. [0003] Generally speaking, a storage system corresponds to multiple OSDs (Object Storage Device), each OSD corresponds to a set of journal and omap for storing data, and each OSD corresponds to a hard disk, which can be SSD (Solid State Drives, solid-state drives), or HDDs (Hard Disk Drives, mechanical hard drives). For a storage system, the number of HDDs i...
