我正在使用 Ubuntu 20.40，在其中创建一个包含映像上的用户数据/元数据的 ISO，然后从中启动 VMware VM。我观察了输出，它似乎创建了逻辑卷和挂载点；它安装了软件、我配置的用户、更新等，但每次我得到的都是一个我没有要求的文件系统。我已将其通过 YAML 验证器，使用 cloud-init 对其进行了验证，并将其与其他配置进行了比较，但我无法找出问题所在。
我将其精简到只剩下最基本的部分，但它仍然做同样的事情。以下是用户数据（已清理）：

- {path: /var/log/audit, device: format-5, type: mount, id: mount-5}
完成后，我重新启动虚拟机，文件系统如下所示。磁盘空间充足（250GB）且 RAM 为 10GB。资源不是问题。cloud-init 日志没有告诉我任何明显的信息（其中有很多）：

udev 4.9G 0 4.9G 0% /dev
tmpfs 995M 1.2M 994M 1% /run

我看不出这里出了什么问题。
谢谢！

这是我的存储>配置部分

上述配置将创建以下存储布局
xvda 20G

├─ubuntu--vg-ubuntu--lv--root ext4 3.8G /

我故意删除了“var”部分中的“size”参数。文档指出我们可以输入 -1 来填充剩余空间，但在我的情况下不起作用，缺少大约 2 个字节。
我没有找到足够的信息，所以我希望它能够帮助遇到同样问题的人。
