我为此苦苦挣扎了一个多月，并尝试了论坛上发布的许多其他解决方案。
由于备份脚本失败，Compute Engine VM 实例磁盘消耗过多，此后 SSH 身份验证不起作用。
我已经尝试过以下操作：A.从 GCP 控制台增加磁盘大小。
B. 拍摄磁盘快照并从中创建新实例
C. 已创建带有新磁盘的新实例，并将快照作为附加磁盘附加（当我删除附加的快照时，此实例可以正常工作，但如果我附加有问题的磁盘，它就无法正常工作）
我尝试过我遇到的各种启动脚本
尝试了这个解决方案 sudo resize2fs /dev/sda1

答案1
由于我找不到任何解决方案，我从上次备份中创建了另一个计算引擎实例，并重新输入了丢失的几天的数据。幸运的是，这是一个活动很少的网站服务器，否则唯一的其他解决方案就是采用谷歌昂贵的支持服务！
从日志中我发现谷歌本身存在一个严重故障，该故障严重损坏了磁盘，导致所有服务都无法启动。
我注意到触发点是当他们引入一些新的监控服务时，同时我的磁盘由于备份脚本失败而空间不足。所有这些都同时发生。这当然是猜测，因为我无法在没有任何系统访问权限的情况下准确识别问题。
答案2
我建议：
1- 对磁盘（无法通过 SSH 连接的实例）进行快照。2- 从该快照创建新磁盘，并确保新磁盘大于原始磁盘。3- 使用新启动磁盘创建新实例，并将快照磁盘作为附加磁盘附加。
如果问题仍然存在，您可以尝试通过串行端口进行连接。如果这仍然不起作用，可能需要运行启动脚本来卸载连接的磁盘，看看您是否可以连接到实例，然后重新安装它以访问数据。
