Google VM Instant - 无法访问 SSH

Question

我是从 Google Click to Deploy 6 个月前安装的 ERPNext 并使用该软件，该软件从上周开始工作，我无法访问系统和 SSH

当使用 SSH 连接时，系统显示通过 Cloud Identity-Aware Proxy 连接失败，代码为 4003，有人可以帮我解决这个问题吗？

知道如何解决这个问题吗？

要解决此问题，您应该在启动盘上执行运行 fsck 命令。

要做到这一点，您可以按照以下步骤操作：

stop 你的虚拟机实例（不要删除它）：

gcloud compute instances stop [INSTANCE_NAME]

Before detaching the boot disk from the instance, you must stop the instance. There is no need to unmount the disk.

detach 您的 VM 实例的启动磁盘（通常 DISK_NAME 与 INSTANCE_NAME 相同）：

gcloud compute instances detach-disk [INSTANCE_NAME] --disk=[DISK_NAME]

create调试虚拟机实例：

gcloud compute instances create debug-instance

attach 将您的引导磁盘作为调试实例的非引导磁盘，但不要挂载它：

gcloud compute instances attach-disk debug-instance --disk [DISK_NAME] --device-name debug-disk

connect 到调试实例：

gcloud compute ssh debug-instance

查找磁盘的根分区，用命令ls -l /dev/disk/by-id（在本例中为/dev/sdb1）用part1符号标识：

$ ls -l /dev/disk/by-id
total 0
lrwxrwxrwx 1 root root  9 Feb 13 14:56 google-debug-disk -> ../../sdb
lrwxrwxrwx 1 root root 10 Feb 13 14:56 google-debug-disk-part1 -> ../../sdb1
lrwxrwxrwx 1 root root 11 Feb 13 14:56 google-debug-disk-part14 -> ../../sdb14
lrwxrwxrwx 1 root root 11 Feb 13 14:56 google-debug-disk-part15 -> ../../sdb15
lrwxrwxrwx 1 root root  9 Feb 13 14:56 google-persistent-disk-0 -> ../../sda
lrwxrwxrwx 1 root root 10 Feb 13 14:56 google-persistent-disk-0-part1 -> ../../sda1
lrwxrwxrwx 1 root root 11 Feb 13 14:56 google-persistent-disk-0-part14 -> ../../sda14
lrwxrwxrwx 1 root root 11 Feb 13 14:56 google-persistent-disk-0-part15 -> ../../sda15
lrwxrwxrwx 1 root root  9 Feb 13 14:56 scsi-0Google_PersistentDisk_debug-disk -> ../../sdb
lrwxrwxrwx 1 root root 10 Feb 13 14:56 scsi-0Google_PersistentDisk_debug-disk-part1 -> ../../sdb1
lrwxrwxrwx 1 root root 11 Feb 13 14:56 scsi-0Google_PersistentDisk_debug-disk-part14 -> ../../sdb14
lrwxrwxrwx 1 root root 11 Feb 13 14:56 scsi-0Google_PersistentDisk_debug-disk-part15 -> ../../sdb15
lrwxrwxrwx 1 root root  9 Feb 13 14:56 scsi-0Google_PersistentDisk_persistent-disk-0 -> ../../sda
lrwxrwxrwx 1 root root 10 Feb 13 14:56 scsi-0Google_PersistentDisk_persistent-disk-0-part1 -> ../../sda1
lrwxrwxrwx 1 root root 11 Feb 13 14:56 scsi-0Google_PersistentDisk_persistent-disk-0-part14 -> ../../sda14
lrwxrwxrwx 1 root root 11 Feb 13 14:56 scsi-0Google_PersistentDisk_persistent-disk-0-part15 -> ../../sda15

运行对根分区的文件系统检查：

sudo fsck /dev/sdb1

例如：

debug-instance:~$ sudo fsck /dev/sdb1
fsck from util-linux 2.33.1
e2fsck 1.44.5 (15-Dec-2018)
/dev/sdb1: clean, 53782/647168 files, 396250/2588667 blocks

stop 调试实例 VM 实例并分离您的引导磁盘：

gcloud compute instances stop debug-instance
gcloud compute instances detach-disk debug-instance --disk [DISK_NAME]

reattach VM 实例的启动磁盘：

gcloud compute instances attach-disk [INSTANCE_NAME] --disk=[DISK_NAME] --boot

start 您的虚拟机实例：

gcloud compute instances start [INSTANCE_NAME]

check 您的 VM 实例通过串行端口的启动日志。
delete 调试实例：

gcloud compute instances delete debug-instance

此外，请查看文档 Detaching and Reattaching Boot Disks and Troubleshooting VM start up。
