galera节点上的完整SST无法启动（缺少“WSREP：准备好的SST请求”）

我有一个带有3个节点的galera集群（10.0.27），每个节点都在一个专用服务器上 . 重新启动其中一个服务器后，该节点无法再加入群集，也无法执行完整的SST . 实际上，就像mysql'misses'来发布一些命令一样 .

我有一个第二个'开发'集群，相同的配置工作完美，我没有添加节点的问题 . 当我为完整的SST添加一个节点时，我注意到工作集群与不工作之间的区别：

不同之处在于：

rsyncd[13316]: rsyncd version 3.1.1 starting, listening on port 4444

在工作集群上，以下行是

WSREP: Prepared SST request: rsync|192.***.***.**2:4444/rsync_sst

在不工作的集群上，此行不会出现，就像没有发出SST请求一样 .

如果您认为可以帮助查找问题，我可以提供有关配置的更多信息 .

谢谢你的帮助 ！
