我在 Azure 上使用 juju 并设法部署（juju-gui、mysql、tomcat7）。并且我还破坏了一些服务。
我应该提到，我还使用命令启用了 juju 高可用性
juju ensure-availability
当我尝试部署 HaProxy charm 时，它卡住了，提示
agent-state-info: 'cannot get machine 9: EOF'
我在谷歌或 juju 文档中找不到这个。
请问这个错误信息是什么意思？下次如何避免？我的配置有误吗？如何解决？执行后，juju resolved haproxy/0我ERROR unit "haproxy/0" is not in an error state应该销毁这个魔法吗？谢谢
这是我的juju status haproxy/0结果
