Problems solved by technology

[0004] However, in the existing dual-controller storage devices, when one controller is abnormal, some storage services are still abnormal, and the stability of data stored in the device is poor.

Embodiment approach

[0134] As an implementation manner, the device further includes a judging module (not shown in the figure) applied to the first controller,

[0135] The judging module is configured to judge whether the first controller obtains the metadata in the second controller from the second controller; if not, trigger the scanning module 130 .

[0136] As an implementation manner, the second controller stores verification information corresponding to each storage device under its own management;

[0137] The device also includes a generation module and a storage module (not shown in the figure) applied to the first controller, wherein,

[0138] The generation module is configured to, for each storage device determined by the determination module, generate a piece of verification information corresponding to the storage device;

[0139] The storage module is configured to store the verification information corresponding to the storage device generated by the generation module in the sto...

Abstract

Embodiments of the present invention provide a data processing method, device, and distributed storage system. The method and device are applied to a dual-control storage server. The dual-control storage server includes two controllers. If one controller is abnormal, the other The controller determines the storage device under the management of the abnormal controller, the other controller scans the data in the determined storage device, obtains the metadata of the storage device, and uses the metadata to read the data stored in the determined storage device It can be seen that in this solution, if one controller is abnormal, the other controller will take over the abnormal controller to provide external services, which improves the stability of the data stored in the dual-control storage server.

Description

technical field [0001] The present invention relates to the technical field of distributed storage, in particular to a data processing method, device and distributed storage system. Background technique [0002] Currently, some storage devices include two controllers, and these storage devices are also called dual-controller storage devices. The two controllers in the dual-controller storage device share hardware resources such as storage resources, power supply, and HBA (Host Bus Adapter, host bus adapter in English). [0003] In a dual-control storage device, when one controller is abnormal, such as network abnormality, system abnormality, etc., the other controller can still continue to operate normally. In this way, the dual-control storage device can still provide some normal storage services. [0004] However, in the existing dual-controller storage device, when one controller is abnormal, some storage services are still abnormal, and the stability of data stored in t...
