A method, apparatus and system for data disaster tolerance are provided in embodiments of this disclosure, the method comprising: receiving node failure information from a node; detecting along a predecessor direction and a successor direction of a failure node indicated in the node failure information according to a pre-stored node sequence to determine a first effective predecessor node and a first effective successor node, and all failure nodes between the first effective predecessor node and the first effective successor node; instructing those of all effective nodes that have local content registration index stored on the failure nodes and the first effective successor node to perform a primary index recovery process, respectively, so as to recover primary indexes of all of the failure nodes into the primary index of the first effective successor node.
摘要:
The present invention discloses a method, an access node, and a system for obtaining data. The method includes: receiving a data obtaining request sent by a client and obtaining an authentication result of multilevel authentication performed on the data obtaining request; when the authentication result of the data obtaining request is successful, obtaining data to be obtained corresponding to the data obtaining request and sending the data to be obtained to the client, or, obtaining information about a content storage node to which the data to be obtained corresponding to the data obtaining request belongs and sending the information about the content storage node to the client. The embodiments of the present invention may ensure security of data obtaining, avoid a single-point failure or bottleneck, and reduce the cost when data is obtained from a data storage platform.
摘要:
An automatic expansion method, a management device, and a management system are disclosed in the embodiments of the present invention. In the embodiments of the present invention, information about added management nodes is received from a node management server when a new node is added, where the information about the added management nodes comprises at least address information of the added management nodes; the address information of the added management nodes is used to obtain an index corresponding to a continuous identifier (ID) segment; and an adding message of the new node is sent to all added management nodes, where the adding message includes at least a continuous ID segment managed by the new node and address information of the new node.
