Method, device and equipment for returning quotas and computer storage medium

Abstract

An embodiment of the invention discloses a method, a device and equipment for returning quotas and a computer readable storage medium. The method includes transmitting permission application information and quota value application information to a metadata service side according to write operation requests transmitted by users, wherein the quota value application information includes pre-application quota values; acquiring authorization information and allocated quota values fed by a metadata server; receiving data written by the users, recording timestamps of the data currently written by theusers, and updating the allocated quota values according to the data size of the currently written data to obtain current quota residual values; judging whether difference values of the timestamps ofthe currently written data and current timestamps are larger than preset values or not, judging whether the current quota residual values are larger than 0 or not if the difference values of the timestamps of the currently written data and the current timestamps are larger than the preset values, and returning the current quota residual values to the metadata server if the current quota residualvalues are larger than 0 so as to update total quota residua values by the aid of the metadata server according to the current quota residual values. The quota value application information comprisespre-application quota values. The method, the device, the equipment and the computer readable storage medium have the advantages that the utilization rate of quota spaces can be increased, and the performance of systems can be enhanced to a certain extent.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of distributed file systems, and in particular, to a quota return implementation method, device, device, and computer-readable storage medium. Background technique [0002] When the user writes data, the client needs to pre-apply for the quota to the metadata server. After successfully applying for the quota value, the client writes the data. If the client finishes writing the data, the requested quota value remains , the remaining quota value will be reserved for the next data write. However, when multiple clients have remaining quota values ​​when the user finishes writing data, and the metadata server does not have enough quota values ​​for other clients to apply for, it will cause other clients to apply for quotas when the user writes data The value fails, and the quota occupied by the client with the remaining value of the quota cannot be used by other clients, thereby reducing th...
