Abstract: Log processing provides a status message of a storage node cluster is obtained by a first node. The status message marks a master storage node of the storage node cluster. The first node can send a first write operation request to the master storage node based on the status message so that the master storage node agrees on a first write operation after agreeing on a received log with a slave storage node in the storage node cluster. The first node receives a feedback message sent after the master storage node agrees on the first write operation with the slave storage node in the storage node cluster. The feedback message includes identification information and a response to the first write operation request. The first node can send to the master storage node a target message including a current iteration identifier, and the master storage node can use the current iteration identifier to determine whether the target message is from a latest master compute node.

Abstract: Various embodiments provide a storage cluster configuration change method, an apparatus, a computer system, and the like. In a storage cluster that uses a consensus replication protocol, when half of storage nodes become faulty, if it is determined that at least one storage node exists in the storage cluster after the fault, and a latest log index number of the storage node is greater than or equal to an index number of a committed log provided by the storage cluster for a client, an arbitration module sends a forced cluster configuration change instruction to a fault-free storage node. The forced cluster configuration change instruction is used to instruct the fault-free storage node to change local cluster configuration information.

Abstract: A method, apparatus, and system for disaster recovery of an Internet Protocol (IP) Multimedia Subsystem (IMS), where the method includes triggering a redundant Call Session Control Function (CSCF), obtaining, by the redundant CSCF, user backup data of registered IMS Private User Identities (IMPIs) that are associated with IMPUs and user service configuration data of IMS Public User Identities (IMPUs) in an IMS subscription from a network storage entity of a user; and recovering, by the redundant CSCF, a corresponding service according to the obtained user backup data of the registered IMPIs and user service configuration data of the IMPUs in the IMS subscription. Hence, the one-IMPU multi-IMPI, one-IMPI multi-IMPU, or multi-IMPI multi-IMPU service can be recovered, and this enables the user to have better service continuity experiences.
