Embodiment Construction

[0033] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] Memory may include non-permanent storage in computer readable media, in the form of random access memory (RAM) and / or nonvolatile memory such as read only memory (ROM) or flash RAM. Memory is an example of computer readable media.

[0035] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random access memory (SRAM), dynamic ran...

Abstract

The invention provides a file self-reduction method and device for distributed cluster storage. The method includes allocating storage space quotas for a directory or a user; counting storage space quota usage information during directory or user data operations in real time; reporting the quota usage information; and controlling directory or user data operations based on the reported quota usageinformation. By the method, a certain amount of space can be automatically pre-allocated for a target user, and when the pre-allocated space is reached, any operation that causes the directory to become large is prohibited.

Description

technical field [0001] The invention relates to the field of computer servers, in particular to a file self-simplification method and device for distributed cluster storage. Background technique [0002] With the development of the times, a large number of data files are generated. The computer manages and stores data through the file system, and simply increases the number of hard disks to expand the storage capacity of the computer file system. In terms of capacity size, capacity growth rate, data backup, data Safety and other aspects of the performance are unsatisfactory. The distributed file system can effectively solve the problem of data storage and management. A file system fixed at a certain location can be extended to any number of locations / multiple file systems, and many nodes form a file system network. Each node can be distributed in different locations, and the communication and data transmission between nodes can be carried out through the network to establis...
