A data processing method and device, and a distributed storage system are described. The method and device are applied in a dual-control storage server. The dual-control storage server comprises two controllers. If one controller fails due to abnormalities, the other controller determines the storage device managed by the failed controller, and the other controller scans the data in the determined storage device to obtain 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 the place of the failed controller to provide external services. This improves the stability of the data storage by the dual-control storage server.

Each object block group includes a data block storing object data, and an index block storing an index of the object data. The primary metadata block is located at a head of the disk; and the backup metadata block is located at a tail of the disk. The at least one object block group is located between the primary metadata block and the backup metadata block. In reading or writing object data, the index in the index block, the metadata in the primary metadata block and the metadata backed up in the backup metadata block can be separately operated.

Embodiments of the present application provide a method and apparatus for displaying objects. In the method, data segments of to-be-stored data are stored in storage objects. A storage object is a minimum unit for data storage. The difference between the number of data segments stored in a storage object and that of another storage object is no more than a first preset threshold. Data segments are equally stored, to the greatest extent, into storage objects. The case that data having segments lost due to failure of a storage object cannot be restored is avoided.
