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, Incremental failed, or Paused state can be changed.
  • Only synchronization tasks from GaussDB Primary/Standby to Kafka can be changed.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select a region and project.
  3. Choose Databases > Data Replication Service. The Data Replication Service page is displayed.
  4. On the Data Synchronization Management page, select the target task and choose More > Change to Primary/Standby in the Operation column.
  5. 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.
  6. 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 type change is complete, you can check that the parent task has two subtasks: one primary task and one standby task.
