屏蔽虚拟机发生故障后，有没有办法修复 GCP 虚拟机上的 SSH

我有一台 GCP VM，上面安装了带有 Drupal 的 Docker。带有 SSD 10Go 的 e2-medium 在将磁盘大小增加到 20GB 后，我无法再通过 SSH 访问 VM。

我的虚拟机由于启动完整性检查而无法启动。所以我用这个来解决不完整性问题https://cloud.google.com/compute/shielded-vm/docs/integrity-monitoring#diagnosing-failure 但 SSH 不起作用。

我遇到了连接被拒绝的问题

ssh: connect to host [HOST_IP] port [HOST_PORT]: Connection refused

我还尝试使用（ssh-keygen）生成几个 ssh 密钥，并将发布密钥添加到服务器上，但没有结果。

这是 ssh_config：

Include /etc/ssh/ssh_config.d/*.conf

#   ForwardX11 no
#   ForwardX11Trusted yes
#   PasswordAuthentication yes

这是 sshd_config：

#GSSAPIKeyExchange no

# Set this to 'yes' to enable PAM authentication, account processing,

PermitRootLogin no
# If you just want the PAM account and session checks to run without

我可以访问虚拟机上的串行控制台，但我不知道该去哪里查看。你能帮我吗？我的配置有错误吗？

请看 lsof -i 的结果:22

COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
sshd    1265 root    3u  IPv4  21008      0t0  TCP *:ssh (LISTEN)
sshd    1265 root    4u  IPv6  21019      0t0  TCP *:ssh (LISTEN)
