Abstract

The invention provides a distributed storage system and method based on a data arbiter copy and used for online distributed data storage. The method comprises the following steps that: S1, the distributed storage system receives a data write-in operation request; S2, the distributed storage system starts data write-in operation after receiving the data write-in operation request and synchronously writes the written data into a data copy storage module; S3, the data write-in operation of the data copy storage module is completed, and the data copy storage module directly returns writing operation confirmation information; S4, a data arbiter copy module continuously and asynchronously write in data from the data copy storage module, and a complete data arbitration information backup used for data migration and restoration is carried out; and S5, the write-in operation of the data arbiter copy module is completed, and asynchronous writing operation confirmation information is returned. The distributed storage system and method solve the problems in the prior art that an existing distributed storage system has a relatively small effectively storage space, is low in reading and writing efficiency and has difficulty in data restoration, and a conventional double-copy storage method leads to a brain-split phenomenon.

Description

technical field [0001] The invention relates to a distributed storage system, in particular to a distributed storage system and method based on a data arbiter copy. Background technique [0002] With the development of information technology, the global data is exploding. Centralized storage servers rely too much on traditional magnetic storage devices, which is inconvenient to operate and difficult to expand performance. However, the recent online centralized storage servers need to be improved in technology, which cannot meet the requirements of high reliability and scalability of the system, and will affect performance. Hotspots, abnormal errors occur from time to time. Online distributed storage solves these problems well. [0003] Ceph is an open source unified distributed storage system, which has excellent data access performance, system reliability has been significantly improved, and storage performance is scalable. It is used in e-commerce, online enterprise data...
