二者均改编自：

在GCP控制台中，当我看到实例绿灯时，我立即单击实例

ssh

按钮并成功连接到实例。但是，如果我一直打开到实例的新ssh连接，它们都会工作，直到我在

/var

上的装载完成。我通过：

df-h

在运行的ssh连接（通常是第一个）中查找挂载，看到挂载完成。我可以看到

/dev/sdb 197G 60M 197G 1%/var

。在尝试失败之前，装载未显示。但是在它出现之后，没有任何东西会ssh到它。已尝试在控制台中执行

gcloud compute ssh[实例名称]

的

按钮（shell）。尝试使用[user name]@[external IP]
填充腻子
我试着只等待5分钟，以ssh方式连接到实例（挂载将在那时完成），这也不起作用
重要提示：
如果我注释掉所有可以无限期连接的启动脚本行，就没有SSH
问题。我试着创建一个新的磁盘并将其连接起来
因此，似乎是磁盘的装载导致了ssh问题
早期的ssh连接继续正常工作，即使我不能创建一个新的连接
当ssh连接失败时，我会在ssh窗口中看到：
“连接失败
与SSH服务器通信时出错。请检查服务器和网络配置。“
你知道这是什么原因吗
实例是linux发行版SUSE 12
我的安装说明来自这里：

如果有一个很好的方法可以避免这种情况（请提供），但我真的很想知道我做错了什么
我不熟悉GCP、云、python、ssh和Linux。（这个问题中的所有内容都是全新的！）
如果我注释掉启动脚本行，按照描述运行所有内容，ssh到保险，手动运行启动脚本命令，我没有得到任何错误，我仍然需要测试我是否创建了另一个ssh连接。我们这样做并报告。
装载在/var
上，其中包含与ssh
相关的数据（以及其他内容），使得到达/var
的系统可以看到一个空白磁盘。数据必须保存在别处（cp-ar
），装载到var，然后将数据移回
我先前的回答是错误的
