创建一个新的raid1 mdadm设备将创建两个不需要的分区

Question

我正在尝试用raid1 (用mdadm)创建一个luks设备。但是，它创建了两个分区，而不是一个分区，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  

这是我所用的程序：

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lsblk --我看到sde和sdf都有两个分区？我怎么才能避免呢？

编辑:当使用mdadm创建数组时，我得到以下内容，这可能是问题的原因，但是如何消除它呢？

$ 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。像以前一样做每件事，但之后：

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
