我有一个 DRBD 集群，其中一个节点关闭了几天。单节点运行良好，没有出现任何问题。当我打开它时，我遇到了一种情况，所有资源都停止了，一个 DRBD 卷是辅助卷，其他卷是主要卷，因为它似乎试图对刚刚打开的节点执行角色交换（ha1 处于活动状态，然后我打开 ha2）为了便于理解日志，在 08:06）
我的问题：
- 谁能帮我弄清楚这里发生了什么？（如果这个问题被认为太费力，我愿意考虑付费咨询来获得正确的配置）。
- 作为一个附带问题，如果情况自行解决，是否有办法让电脑自行清理资源？如果故障转移后故障情况清除，LinuxHA 集群不需要干预，所以我要么被宠坏了，要么不知道如何实现这一点。
下面是我能想象到的所有可能有用的信息。
