Changing a Single-AZ Task to a Dual-AZ Task
DRS allows you to change a single-AZ task to a dual-AZ task, improving task reliability while remaining the original task.
Constraints
- A dual-AZ task cannot be changed to a single-AZ task.
- Only tasks in the Incremental or Incremental failed state can be changed.
- Only synchronization tasks from GaussDB Centralized to Kafka can be changed.
Procedure
- Log in to the management console.
- Click
in the upper left corner and select a region and project.
- Choose Databases > Data Replication Service. The Data Replication Service page is displayed.
- On the Data Synchronization Management page, select the target task and choose More > Change to Primary/Standby in the Operation column.
- On the displayed page, select the standby AZ. If the task is over a public network, you need to specify the EIP of the standby task and click OK.
- After submitting the change, click Back to Task List. On the Data Synchronization Management page, the task status is Changing to primary/standby. After the task is changed, you can see that the parent task contains one primary and one standby subtask. The standby subtask and the parent task are in the Configuration state.
- Click Edit in the Operation column of the parent task. On the displayed page, test the connections to the source and destination databases. If the connections are normal, click Next.
- On the Confirm Task page, click Start Task. If the task is billed on a yearly/monthly basis, click Pay and Start to go to the payment page.
