# 1F-1F-1F 三节点分布在三个地域的 OceanBase 集群创建多副本业务租户时失败的原因和解决方法

更新时间：2026-06-04 01:56

适用版本： V2.1.x、V2.2.x、V3.1.x、V3.2.x、V4.0.x、V4.1.x、V4.2.x、V4.3.x、V4.4.x 内容类型：Troubleshoot  

本文主要介绍 `1F-1F-1F` 三节点分布在三个地域的 OceanBase 集群创建多副本业务租户时失败的原因和解决方法。

## 问题现象

OceanBase 集群分布架构如下图所示：三台 OBServer 机器分别位于不同地域的不同机房中：

![image01](https://obbusiness-private.oss-cn-shanghai.aliyuncs.com/doc/img/knowledge-base/database/cluster-management/2000.observer/11603.reasons-for-failure-create-multi-replica-business-tenant-ob-cluster-with-three-nodes-distributed-three-regions/20250912reasons-for-failure-create-multi-replica-business-tenant-ob-cluster-with-three-nodes-distributed-three-regions01.png)

继续通过 OCP 为该集群创建业务租户时遇到了报错：

![image02](https://obbusiness-private.oss-cn-shanghai.aliyuncs.com/doc/img/knowledge-base/database/cluster-management/2000.observer/11603.reasons-for-failure-create-multi-replica-business-tenant-ob-cluster-with-three-nodes-distributed-three-regions/20250912reasons-for-failure-create-multi-replica-business-tenant-ob-cluster-with-three-nodes-distributed-three-regions02.png)

![image03](https://obbusiness-private.oss-cn-shanghai.aliyuncs.com/doc/img/knowledge-base/database/cluster-management/2000.observer/11603.reasons-for-failure-create-multi-replica-business-tenant-ob-cluster-with-three-nodes-distributed-three-regions/20250912reasons-for-failure-create-multi-replica-business-tenant-ob-cluster-with-three-nodes-distributed-three-regions03.png)

由上述可知 `1F-1F-1F` 的三节点 OceanBase 集群，三个 Zone 分别在不同的三个 Region，不管创建什么样的 Primary_zone 的业务租户，都会遇到报错：**租户 Zone 第一优先级 [zone1] 所在的地域 Hangzhou 需要至少有 2 个全功能型副本**，实际只有 1 个全功能型副本，或者报错：**租户 Zone 第一优先级 [zone1, zone2] 不允许跨地域，实际跨地域 [Hangzhou, shanghai]**。

## 问题原因

因为 OBServer 内核的限制，创建业务租户时，Primary Zone 目前不支持跨 Region：

```shell
MySQL [oceanbase]> create resource unit unit1 min_cpu=3, max_cpu=3, memory_size='12g';
Query OK, 0 rows affected (0.005 sec)

MySQL [oceanbase]> create resource pool pool1 unit = 'unit1', unit_num = 1, zone_list = ('zone1', 'zone2', 'zone3');
Query OK, 0 rows affected (0.016 sec)

MySQL [oceanbase]> create tenant mysqlt resource_pool_list = ('pool1'), primary_zone = 'RANDOM' set ob_tcp_invited_nodes = '%', ob_compatibility_mode = 'mysql', recyclebin = off;
ERROR 1235 (0A000): tenant primary zone span regions not supported
MySQL [oceanbase]>
MySQL [oceanbase]> create tenant mysqlt resource_pool_list = ('pool1'), primary_zone = 'zone1,zone2' set ob_tcp_invited_nodes = '%', ob_compatibility_mode = 'mysql', recyclebin = off;
ERROR 1235 (0A000): tenant primary zone span regions not supported
MySQL [oceanbase]>
MySQL [oceanbase]> create tenant mysqlt resource_pool_list = ('pool1'), primary_zone = 'zone1,zone2,zone3' set ob_tcp_invited_nodes = '%', ob_compatibility_mode = 'mysql', recyclebin = off;
ERROR 1235 (0A000): tenant primary zone span regions not supported

```

同时 OBServer 内核要求多副本业务租户 Zone 第一优先级 [zone1] 所在的地域需要至少有 2 个全功能型 F 副本：

MySQL [oceanbase]> create tenant mysqlt resource_pool_list = ('pool1'), primary_zone = 'zone1' set ob_tcp_invited_nodes = '%', ob_compatibility_mode = 'mysql', recyclebin = off;
ERROR 4179 (HY000): primary zone F type replica not enough in its region not allowed
MySQL [oceanbase]>
MySQL [oceanbase]> create tenant mysqlt resource_pool_list = ('pool1'), primary_zone = 'zone1;zone2,zone3' set ob_tcp_invited_nodes = '%', ob_compatibility_mode = 'mysql', recyclebin = off;
ERROR 4179 (HY000): primary zone F type replica not enough in its region not allowed

```

## 适用版本

- OceanBase 数据库 V2.x、V3.x、V4.x 版本。
 - OCP V3.x、V4.x 版本。

## 解决方法

1. 当前 `1F-1F-1F` 三节点分布在不同地域的 OceanBase 集群只支持创建单副本业务租户：

   ![image04](https://obbusiness-private.oss-cn-shanghai.aliyuncs.com/doc/img/knowledge-base/database/cluster-management/2000.observer/11603.reasons-for-failure-create-multi-replica-business-tenant-ob-cluster-with-three-nodes-distributed-three-regions/20250912reasons-for-failure-create-multi-replica-business-tenant-ob-cluster-with-three-nodes-distributed-three-regions04.png)
 2. 如果需要创建多副本租户，需要先卸载集群后，重新设置主机的 Region，保证同一个Region下至少存在两个 Zone。
 3. 使用其它推荐的高可用部署方案，详情请参见：[三地五中心五副本部署](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000001499476)。
