The invention discloses a management method and device for double metadata servers. Each metadata server comprises a master list and a slave list. The management method includes: one metadata server stores received information in the master list of the server and syncs the information to the slave list of the other server; each metadata server operates a copy according to the information stored in the master list. The system of double metadata servers is achieved through master and slave modes; each metadata server operates the copy according to the information stored in the corresponding master list; service capacity of the system can be improved; in addition, the information of the other metadata server is stored in the metadata server; fault tolerance of the system can be enhanced, and the management way of the double metadata server system in the master and slave modes can be simplified.
