Embodiment 1

[0030] figure 1 A flow chart showing the implementation of the method for managing the storage space of the distributed file system provided by Embodiment 1 of the present invention is described in detail as follows:

[0031] In S101, acquire instructions and parameters for operating storage resources;

[0032] In this embodiment, the storage resources may be hard disks, storage nodes, and storage volumes.

[0033] In this embodiment, the instructions may be creating a storage volume, deleting a storage volume, adding storage space to a storage volume, reclaiming storage space of a certain volume, creating a node, deleting a node, and so on.

[0034] Optionally, S101 specifically includes: receiving user instructions and parameters for operating storage resources, that is, directly inputting instructions and setting parameters for operating storage resources by users, so that users can actively participate in the management of storage space of storage resources.

[0035] Opt...

Embodiment 2

[0077] image 3 It shows the structural diagram of the management system of the storage space of the distributed file system provided by the second embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown. The system can be built into the distributed file A software unit, a hardware unit, or a combination of software and hardware in the storage space management device of the system.

Abstract

The invention relates to the technical field of storage and provides a memory space management method of a distributed file system and a system. The method comprises steps that: a storage resource obtains instructions and parameters of storage resource operation; finding a preset storage resource recording linked list; obtaining storage resource information corresponding to the instructions and the parameters; carrying out corresponding operations to the distributed file system according to the storage resource information. The memory space management method of the distributed file system and the system achieve the dynamic elasticity distribution and management to the memory space of the distributed file system.

Description

technical field [0001] The invention belongs to the technical field of storage, and in particular relates to a method and system for managing storage space of a distributed file system. Background technique [0002] At present, there are two main management methods for storage space, the management method based on the centralized architecture and the management method based on the distributed architecture. Only some professional storage companies can provide and implement the above two methods. The storage based on the centralized architecture Space management not only requires expensive professional equipment, but also provides a single interface for external services, and does not have horizontal expansion and dynamic expansion capabilities; traditional distributed architecture-based storage space management is generally static configuration and does not have dynamic expansion capabilities , there is no recovery and release of storage resources during system operation, and...
