Problems solved by technology

In order to avoid this inconsistency, the Lustre file system implements a dynamic adjustment scheme on the data server, allowing each data server to negotiate and update their local quotas when the global quota remains unchanged, so as to solve the problem of uneven local quotas problem, which in turn impacts server performance

Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with accompanying drawings and examples.

[0034] figure 1 Shown is a schematic flow chart of the method of the present invention.

[0035] The specific steps of the network storage system quota management and control method in this embodiment are:

[0036] First start the metadata server, run the main thread on it, the quota periodic synchronization client thread and the administrator service thread. The main thread provides metadata services, the quota synchronization client thread periodically queries the object storage server for user resource usage information, and the administrator service thread receives requests from the administrator client thread on the management end and returns the processing results to the management end. Start the object storage server, run the main thread and the quota periodic synchronization service thread. The main thread provides the data storage service of the ...

Abstract

The invention discloses a management and control method for user quota in a multi-network storage system. The method comprises the following steps of starting a metadata server, starting an object storage server, starting a management end, carrying a client end, controlling quotas and back writing quotas. The invention further discloses a management and control system for user quotas. The system comprises a management end, a client end, a metadata server and an object storage server; the management end has an administrator client thread; the client end comprises a quota control module; the metadata server comprises a metadata service thread, a quota regularly synchronized client thread and an administrator service thread; and the object storage server has a document service thread and a quota regularly synchronized service thread. With the adoption of the method and system provided by the invention, waste of network bandwidth caused by unnecessary communication and excessive quota data among servers due to change of resource usage can be avoided, the influence of the quota control function to the system performance is reduced, and meanwhile, a quota consistency synchronizing mechanism is further provided to ensure correctness and consistency of the usage amount of user resources in the system.

Description

technical field [0001] The invention belongs to the technical field of computer storage, and in particular relates to a user quota management and control method in a multi-party network storage system, which is applicable to the quota control management of the network storage system. Background technique [0002] With the explosive increase of information volume, network storage technology has been continuously matured and widely used. In many network storage systems, metadata and data are separated and managed by separate servers, called metadata server and data server respectively. Users store their own data on the data server, using a certain amount of system resources. When multiple users use the system together, the system must provide a method for each user to use system resources reasonably and effectively, so that limited system resources can be used efficiently, that is, user quota management. The user quota referred to in the present invention refers to the numbe...
