我正在尝试在 SuperMicro 服务器上预先安装 Ubuntu 16.04，该服务器有一个 32 GiB SSD 和两个 1TB 磁盘，我在 BIOS 中配置了 RAID1。
我的目标是拥有以下分区：
SSD:
2GB /boot
1 or 2GB swap
28GB /
Raid:
One lvm partition that fills the disk mounted in /opt
这是我的partman-auto预置文件：
### Partitioning

d-i partman/choose_partition select finish

d-i partman/confirm_nooverwrite boolean true
但我得到的是：

我找不到任何关于这种 partman 配置（一个磁盘没有 lvm，另一个有）的文档。有没有一种简单的方法可以自动对我的服务器进行分区？
我的另一个解决方案是partman仅用于对 SSD 进行分区，然后lvm使用 shell 脚本在 raid 上进行设置post-install.sh
答案1
当你尝试完成的任务没有太多 Stack Exchange 解决方案时，你就知道你的工作很出色。我见过的所有预置文件都只能与磁盘驱动器配合使用，因为当时普遍使用的技术是旋转磁盘，而不是 SSD。哎呀，佐登！我们该怎么做？！
