无法使用 Cloud-init 的 growpart 和 resizefs 来增大虚拟机磁盘

我已安装 Ubuntu 20.04 虚拟机服务器Cloud-init。我正在尝试使用 Cloud-init 自动扩展虚拟机的磁盘。虚拟机主机是 ESXi，数据源为 None，因为我只想对新虚拟机进行一些自动配置，而不需要外部数据源。

我已尝试根据以下文档配置 Cloud-init 模块：https://cloudinit.readthedocs.io/en/latest/reference/modules.html#

  • 操作系统：Ubuntu：20.04.6 LTS
  • 云初始化：23.4.4-0ubuntu0~20.04.1

Cloud-init 在启动时执行，但由于未知原因，模块总是被跳过growpart：resizefs

2024-04-03 11:59:04,058 - modules.py[DEBUG]: Running module growpart (<module 'cloudinit.config.cc_growpart' from '/usr/lib/python3/dist-packages/cloudinit/config/cc_growpart.py'>) with frequency always

2024-04-03 11:59:04,059 - handlers.py[DEBUG]: finish: init-network/config-resizefs: SUCCESS: config-resizefs ran successfully

我的最低配置为/etc/cloud/cloud.cfg：

cloud_init_modules:
  - growpart
  - resizefs

growpart:
  mode: auto
  devices: ["/"]

resize_rootfs: true

system_info:
  distro: ubuntu
  paths:
    cloud_dir: /var/lib/cloud/
    templates_dir: /etc/cloud/templates/

分区和文件系统在启动期间处于此状态：

user@server:~$ sudo fdisk /dev/sda

Welcome to fdisk (util-linux 2.34).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

GPT PMBR size mismatch (20971519 != 31457279) will be corrected by write.
The backup GPT table is not on the end of the device. This problem will be corrected by write.

Command (m for help): p

user@server:~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda2       9.8G  3.4G  6.0G  36% /

根据文档，有一个文件可以阻止 growpart，但是阻止程序文件不存在：

user@server:~$ ls /etc/growroot-disabled
ls: cannot access '/etc/growroot-disabled': No such file or directory

什么原因导致模块被跳过？我应该怎么做才能使它们正常工作？

更新：

根据cloud-init query我的设置cloud.cfg不适用：

user@server:~$ sudo cloud-init query combined_cloud_config

...
  "cloud_init_modules": [
    "growpart",
    "resizefs"
  ],
...
 "growpart": {
    "mode": "off"
  },
...
 "final_message": "This comes from cloud.cfg as it should.",
...

Cloud.cfg 似乎适用于其他设置，例如，在配置文件中设置时出现最终消息。

答案1

根据您的日志，它似乎growpart.mode设置为off，指示 growpart 为 noop。

/etc/cloud/cloud.cgf您在问题中写道，这是拼写错误吗？如果是，您的配置将不会被读取。

您能否运行cloud-init query combined_cloud_config并检查是否growpart.mode设置为auto？

如果这没有帮助。您可以报告问题附加日志？

答案2

cloud-init query combined_cloud_config建议命令这答案让我找到了问题的原因。

输出的内容如下：

userdata_raw: "#cloud-config\ngrowpart: {mode: 'off'}\nlocale: en_GB.UTF-8\npreserve_hostname:\...

这是来自/etc/cloud/cloud.cfg.d/99-installer.cfg早期版本镜像遗留的文件。删除这个包含不需要的配置的文件后，模块growpart在启动时启用，分区和文件系统也按应有的方式扩展。
