我们有一个ejabberd集群,它由两台主机组成,这两台主机在重新启动主机期间遇到问题。 我们看到不一致的数据库错误登录。但是,我们无法确定地分析配置或module_init执行中可能实际导致行为的内容。 删除node1上的mnesia可能有助于解决问题。然而,这对于管理目的来说并不理想。如何解决集群ejabberd环境中的Mnesia - inconsistent_database错误?
想请求对以下数据进行审核,并附上一些配置和反馈,说明实际可能导致该行为的原因以及如何减轻该行为。
预先感谢您。
环境配置如下:
- Ejabberd Verison:16.03
- 数量的主机:2
- odbc_type:MySQL的
错误记录:
** ERROR ** mnesia_event got {inconsistent_database, running_partitioned_network, other_node}
重新载入步骤:
- 重新启动节点1
- 重新启动节点2
注意:如果主机以相反的顺序重新启动它不摄制。

感谢您的关注,Mickaël。 –
当我使用术语“重新启动”时,我提到停止并启动同一个节点。在我们的环境中,我们可以随时重新启动第二个节点,但为了正常重新启动第一个节点,第二个节点需要关闭。 Stop02,stop01,start01,start02工作以及停止01,停止02,开始01,开始02.但是,stop01,stop02,start02,start01不起作用。我想得出结论,node01是某种需要首先重新启动的集群主节点。我们希望重新启动节点的原因是为了节省可用节点的实例以避免停机。 –
我们的系统工程师建议的替代方案是从集群中删除节点,进行更改并重新加入,以节省开销,因为订单的管理也需要注意,并且如果主机只是失败且无响应,则不需要执行必要的步骤。我相信更好的转述问题是**“通过随时保持集群在非系统级别中断更改时重新启动的正确方法是什么?”** –
