Abstract

The invention discloses a writing method for data of a distributed storage cluster. The method includes the steps that the preset maximum storage space quota and available storage space capacity of acurrent catalog of data writing are obtained; whether the available storage space capacity is larger than storage space capacity needed for data writing is judged; if yes, a storage space quota of data writing is distributed from the maximum storage space quota through application for MDS of the distributed storage cluster; data writing is executed in storage space appointed by the storage space quota. The maximum storage space quota is set in advance for the catalog of the storage data in the distributed storage cluster, data writing is performed on the distributed storage space quota domainobtained under application, and the using efficiency of storage resources of the distributed storage cluster is effectively improved. The invention further discloses a data writing device for the distributed storage cluster, and meanwhile the data writing device has the advantages.

Description

technical field [0001] The present application relates to the technical field of distributed storage, and in particular to a data writing method and device for a distributed storage cluster. Background technique [0002] The wide application and rapid development of distributed storage clusters provide a broad development space for modern storage technologies. [0003] However, in the prior art, when users use the storage resources of the distributed storage cluster to write data, the storage resources they preempt are often inconsistent with the resources they actually need. In fact, different users actually need different amounts of storage resources, that is, some have a large demand for storage resources, while others have a small demand for storage resources. However, since the existing technology does not set a quota for each user's storage resources, it will cause the situation that each user seizes each other's storage resources and wastes storage resources, thereby...
