google-compute-engine - 磁盘已满，我无法通过 SSH 访问实例

Question

尝试通过 SSH 连接到我的实例时出现错误。它告诉我检查控制台串行输出。据我了解，它说我的磁盘没有更多空间。我该怎么办？我需要 SSH 来清理空间，但无法 SSH，因为没有空间!

这就是我所看到的:

Answer 1

您有不同的选择来解决此问题:

1. Check if your operating system supports automatic resizing :如果是这样，您可以使用 Cloud Console 编辑虚拟机的根磁盘并增加其大小。重新启动实例后，您的虚拟机实例可以自动调整分区大小以识别额外的空间。

2. 使用Interactive Serial Console feature登录到您的虚拟机并清理虚拟机的磁盘或将其复制到另一个存储(如果您稍后需要)。

3. 如果您知道要删除哪些数据，可以配置 startup script删除文件并重新启动虚拟机以运行脚本(例如 rm/tmp/*)。

4. 您可以分离永久磁盘并将该磁盘作为附加磁盘附加到另一台计算机。在临时计算机上，您可以安装它并清理数据或将它们复制到另一个存储(如果稍后需要)。最后使用相同的启动磁盘重新创建原始实例。您可以按照此video中描述的相同步骤进行操作。将您的磁盘添加到另一个 Linux VM，但添加现有的启动磁盘而不是创建新磁盘。

5. Check if your operating system supports automatic resizing :如果是，则创建永久磁盘的快照，并从快照中创建更大容量的新永久磁盘。最后用这个更大的启动磁盘重新创建原始实例。
