Embodiment Construction
[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to 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 another server's slave list;
[0041] Step S103, each metad...

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 field of computers, and in particular, to a management method and device for a dual metadata server. Background technique [0002] In an object service system, objects are generally stored in multiple copies. Different copies of the same object are stored on different OSDs (Object-based Storage Devices, object-based storage devices). The storage 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, metadata server). MDS is an important metadata server in a distributed system. In the application, the fault tolerance mechanism is generally implemented through the active / standby mode, or mutual active / standby can also be adopted. mode to improve the service capability of the system. When the primary MDS is down, the standby MDS can take over, restart the downtime primary MDS, and transfer the control right from the stan...
