Embodiment Construction
[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art fall within the protection scope of the present invention.
[0038] According to an embodiment of the present invention, a method for managing dual metadata servers is provided, and each metadata server includes a master list and a slave list.
[0039] Such as figure 1 As shown, the management method according to the embodiment of the present invention includes:
[0040] Step S101, the metadata server stores the received information in its own master list, and synchronizes the information to the slave list of another server;

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.
Description
Technical field [0001] The present invention relates to the computer field, and in particular, to a method and device for managing a dual metadata server. Background technique [0002] In an object service system, multiple copies are generally used to store objects. Different copies of the same object are stored on different OSDs (Object-based Storage Devices). The storage method of multiple copies is conducive to enhancing the fault tolerance of the system. ability. The metadata of the data is stored on the MDS (Metadata Server). MDS is an important metadata server in a distributed system. In the application, the fault tolerance mechanism is generally achieved through the master-backup mode, or it can also be used as a backup. The model improves the service capability of the system. When the main MDS goes down, the backup MDS can take over, and the down master MDS is started again, and the control right is transferred from the backup MDS back to the main MDS. [0003] In the pr...
