我正在遵循指示从这里在现有 Linux 安装上设置 RAID1。这些说明适用于 Debian/Ubuntu 安装，但我找不到专门针对 AlmaLinux 的说明，因此我尝试进行调整。
我已将原始分区设置复制到空白驱动器，并使用“fdisk /dev/sdh”命令使 LVM Linux 分区“raid 自动检测”。
下一步是创建新的降级 RAID 阵列，mdadm --create /dev/md0 --level=1 --raid-devices=2 missing /dev/sdh1用于两个分区（md0 和 md1 分别用于 sdh1 和 sbh2）。
然而，此时，我得到了这个：
mdadm: partition table exists on /dev/sdh1
mdadm: partition table exists on /dev/sdh1 but will be lost or
meaningless after creating array
mdadm: Note: this array has metadata at the start and
may not be suitable as a boot device. If you plan to
store '/boot' on this device please ensure that
your boot-loader understands md/v1.x metadata, or use
--metadata=0.90
Continue creating array?
...此时我的回答是“不”。
这是 lsblk 的输出：
