CloudFormation AWS::RDS::DBInstance错误“此引擎不允许指定IOP”

Question

我有这个CloudFormation代码

  DatabasePrimaryInstanceAurora0:
    Type: AWS::RDS::DBInstance
    Condition: IsEnvPRO
    Properties:
      Engine: aurora-postgresql
      DBClusterIdentifier: !Ref Aurora0
      DBInstanceClass: db.t4g.medium
      DBInstanceIdentifier: postgres0-0
      DBSubnetGroupName: rds1
      StorageType: gp3

根据这个https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-rds-dbinstance.html#cfn-rds-dbinstance-storagetype，我们很好，但是我从cloudFormation那里得到了那个错误

Resource handler returned message: "Invalid storage type: gp3 (Service: Rds, Status Code: 400, Request ID: 6b75124d-2e57-47fd-bbf3-54ab4f217a82)" (RequestToken: f72ffede-b654-a065-0c5e-cf91c05473d9, HandlerErrorCode: InvalidRequest)

由于@9bO3av5fw5，我添加了

      Iops: 3000

但后来我有..。

Resource handler returned message: "Specifying IOPs is not allowed for this engine (Service: Rds, Status Code: 400, Request ID: 2a558dd8-9e6c-47c8-bef0-af674f05760b)" (RequestToken: 53f0e15e-53b7-d9f5-4817-9d2dcc34bef3, HandlerErrorCode: InvalidRequest)

我的引擎：

     Engine: aurora-postgresql
     EngineMode: provisioned

答案是在这里https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_Storage.html

通用SSD gp3存储支持单AZ和多AZ DB实例，而不支持多AZ DB集群。有关更多信息，请参见高可用性的多AZ部署和多AZ DB集群部署。
