Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] With the development of storage technology, especially for distributed storage systems, the use of BlueStore for local object storage has gradually become the mainstream trend, and the performance of distributed storage has also been greatly improved. Compared with the original FileStore, BlueStore abandons the traditional local file system, and directly uses raw disks as storage media, and needs to manage the allocation and recovery of disk space by its...

Abstract

The invention discloses a disk space management method and device, equipment and a storage medium. The disk space management method comprises: obtaining an allocation instruction for allocating disk space for target data; determining a target disk space matched with the data size of the target data from a first storage structure for managing a large disk space according to the allocation instruction, and if the matched target disk space does not exist in the first storage structure, determining the target disk space from a second storage structure for managing the small disk; and placing the target data into the target disk space, and updating the disk spaces in the first storage structure and the second storage structure. The disk space is managed by using the first storage structure for managing the large disk space and the second storage structure for managing the small disk space, so that the disk space allocation performance and the storage system stability are greatly improved.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a disk space management method, device, equipment and storage medium. Background technique [0002] With the development of storage technology, especially for distributed storage systems, the use of BlueStore for local object storage has gradually become the mainstream trend, and the performance of distributed storage has also been greatly improved. Compared with the original FileStore, BlueStore abandons the traditional local file system, and directly uses raw disks as storage media, and needs to manage the allocation and recovery of disk space by itself. The disk space management method determines the disk space allocation efficiency in the storage system, which in turn affects the performance of distributed storage. However, the existing disk space management methods are too simplistic and cannot effectively manage the raw disks of the distributed storage system. The all...
