Abstract
A method, node and system for controlling version in a distributed system. Wherein, the method includes: a management node is selected from each domain of the distributed system; one is selected as the synchronization source of the distributed system from all the management nodes, and all the management nodes synchronize the time with that of the synchronization source; all the management nodes control the time synchronization of the nodes in their own domain according to the synchronized time; the nodes of the distributed system control the version of the duplicate copy of the storage data according to the synchronized time. According to the technical scheme, it can be realized that the rough time synchronization of the distributed system, the expansibility and the practicability are improved, and the defects of the distributed system in the prior art, such as the poor expansibility and practicability, are solved.
