AI Technical Summary
Technical Problem
Existing technologies pose risks of split-brain and data conflicts after recovery from a database system master failure, and rely on manual intervention, which is inefficient and prone to errors.
Method used
When a primary node fails, the standby database is promoted to the new primary database. Its status is continuously monitored, and role isolation control is implemented during recovery, including disabling write services, restricting election, and marking isolation status to avoid dual-primary operation.
Benefits of technology
Automated isolation was achieved, eliminating the risk of split-brain, avoiding data conflicts and service interruptions, and improving the stability and security of the system.

Abstract
The application provides a database cluster management method, device, equipment, storage medium and product, which are applied to a database cluster. The database cluster includes an initial master library node and at least one standby library node. The method includes the following steps: detecting state information of the initial master library node; when detecting that the initial master library node fails, promoting one standby library node to a new master library node to take over the initial master library node; during the period when the new master library node takes over the initial master library node, detecting the state information of the initial master library node, and when detecting that the initial master library node resumes operation, identifying the initial master library node as a fault recovery node; performing role isolation control on the fault recovery node; the role isolation control includes modifying role configuration information of the fault recovery node. By detecting the initial master library node when it is unavailable to when it resumes operation, performing role isolation control on the initial master library node, and prohibiting the initial master library node from operating as a master library node, data conflicts and automatic isolation caused by double master operation are avoided.
