我正在尝试使用 创建 raid1 (带有mdadm) 设备luks。但是，它会创建两个分区，而不是一个，如下所示：
sde 8:64 0 3,6T 0 disk
`-sde1 8:65 0 3,6T 0 part
`-md0 9:0 0 3,6T 0 raid1
|-storage2 253:2 0 3,6T 0 crypt
|-md0p1 259:0 0 750,7G 0 part
`-md0p2 259:1 0 1,4T 0 part
sdf 8:80 0 3,6T 0 disk
`-sdf1 8:81 0 3,6T 0 part
`-md0 9:0 0 3,6T 0 raid1
|-storage2 253:2 0 3,6T 0 crypt
|-md0p1 259:0 0 750,7G 0 part
`-md0p2 259:1 0 1,4T 0 part
这是我使用的程序：
cfdisk /dev/sde
cfdisk /dev/sdf
mdadm --create --verbose /dev/md0 --level=1 --raid-devices=2 /dev/sde1 /dev/sdf1
cryptsetup -y -v luksFormat /dev/md0
cryptsetup luksOpen /dev/md0 storage2
mkfs.ext4 /dev/mapper/storage2
mkdir -p /media/storage2
mount /dev/mapper/storage2 /media/storage2
为什么使用我看到和lsblk都有两个分区？我怎样才能避免它？sdesdf
编辑：当使用 创建数组时mdadm，我得到以下信息，也许这可能是问题的原因，但如何摆脱它？
$ mdadm --create --verbose /dev/md0 --level=1 --raid-devices=2 /dev/sde1 /dev/sdf1
mdadm: /dev/sde1 appears to be part of a raid array:
level=raid1 devices=2 ctime=Mon Jan 23 20:01:19 2023
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
mdadm: /dev/sdf1 appears to be part of a raid array:
level=raid1 devices=2 ctime=Mon Jan 23 20:01:19 2023
mdadm: size set to 3906885440K
mdadm: automatically enabling write-intent bitmap on large array
Continue creating array?

问题解决了。像以前一样做一切，但然后：
fdisk /dev/md0
d
w
q
cryptsetup -y -v luksFormat /dev/md0
mkfs.ext4 /dev/mapper/storage2
mkdir -p /media/storage2
mount /dev/mapper/storage2 /media/storage2
