4.6. 执行数据库完整性检查

流程

1. 可选：列出实例的后端数据库：

   # dsconf <instance_name> backend suffix list
   dc=example,dc=com (userRoot)

2. 停止实例：

   # dsctl <instance_name> stop

3. 验证数据库。例如，要验证 userRoot 数据库，请输入：

   # dsctl <instance_name> dbverify userRoot

4. 如果验证过程报告了任何问题，请手动修复或恢复备份。

5. 启动实例：

   # dsctl <instance_name> start
