Document Type and Number:
WIPO Patent Application WO/2019/072004
Kind Code:
A1
Abstract:
Provided in an embodiment of the present application is a data processing method, a device, and a distributed storage system, wherein the method and device are applied to a dual control storage server. The dual control storage server comprises two controllers. If one controller is abnormal, the other controller determines the storage device managed by the abnormal controller. The another controller scans the data in the determined storage device to obtain metadata of the storage device, and uses the metadata to read the data stored in the determined storage device. In this solution, if one controller is abnormal, another controller will take over the abnormal controller to provide external services, which improves the stability of data stored in the dual control storage server.
