Question

我正在使用velostrata将一个简单的WordPress网站从AWS迁移到GCP。

我已经在两个VPC之间建立了VPN，并成功配置了velostrata源云和目标云。

迁移过程似乎进行了一段时间。我可以看到在GCP控制台中创建的实例，但是一段时间后它消失了。

当我查看velostrata日志时，错误是：

Finished job: RunInCloud on VM: i-0bc57fc47e893fac0, result: Failed, reason: [Cloud instance boot failed] (Instance boot was unsuccessful)
2019-06-20 15:00:34 DEBUG   VmWorkerImpl

源EC2 VM只是在docker中运行WordPress并指向RDS实例的简单Ubuntu实例。

在这一点上，我真的不知道该怎么做才能工作。知道我应该从哪里开始寻找吗？

谢谢！

每当看到以下错误

Finished job: RunInCloud on VM: whateverVM, result: Failed, reason: [Cloud instance boot failed\](Instance boot was unsuccessful)

您还可以执行以下故障排除步骤

检查实例串行控制台日志中是否存在多个超时，如：

[132.044894] dracut-initqueue[383]: calling: settle
[132.553566] dracut-initqueue[383]: Warning: dracut-initqueue timeout - starting timeout scripts

运行以下命令，它必须仅返回一个内核（不是多个内核，也不是空行）：

sudo grubby --default-kernel

运行以下命令，必须返回所有软件包：

sudo rpm -q iscsi-initiator-utils-iscsiuio iscsi-initiator-utils device-mapper-multipath-libs device-mapper-multipath velostrata-prep

运行以下命令，您希望为快捷方式而不是文件列表提供一个velostrata，多路径，iscsi模块：

sudo lsinitrd /boot/initramfs-uname -r.img | egrep “（（velostrata | multipath | iscsi）”）|头-3

可能的解决方案：

1。卸载并重新安装prep软件包，提供完整的输出以用于调试目的

2。如果已经安装了state，请尝试为当前内核重建initrd

可能的根本原因：

离线准备无法安装在云中运行（迁移任务失败）所需的MPIO功能。
