# 其他问题 | ||
|
||
## 为备库设置日志恢复源失败 | ||
|
||
### 问题现象 | ||
|
||
基于网络的物理备库场景下,为备库设置日志恢复源时,客户端返回 `set tenant itself as log restore source is not allowed` 的错误。 | ||
|
||
### 问题原因 | ||
|
||
为防止用户将"租户自己"设置为恢复源,在设置网络备库的日志恢复源或创建基于网络的空备租户时,要求主库与备库的 `cluster_id` 和 `tenant_id` 两者不能都相同,即至少有一个不相同。如果不满足该条件,就可能会出现上述报错。 | ||
|
||
### 处理方法 | ||
|
||
* 对于主备租户在同一集群的场景,需要检查是否在设置日志恢复源的命令中将租户信息误填为本租户的信息。 | ||
|
||
* 对于主备租户不在同一集群的场景,除了检查租户信息,还需要检查主备租户所在集群的 `cluster_id` 是否相同。使用 OCP 或 OBD 等工具部署的 OceanBase 集群,默认系统会保证 `cluster_id` 唯一,但是手动部署的 OceanBase 集群可能会出现 `cluster_id` 不唯一的情况。 |
