无法将物理卷“/dev/hda”添加到卷组

我正在尝试为我的 docker lvm 创建一个卷组但出现错误。

prem@prem-ubuntu:~/ba/docker-lvm-plugin$ sudo vgcreate volume_group_one /dev/hda
  Device /dev/hda not found (or ignored by filtering).

如何创建不可用的设备？我可以创建设备吗？

步骤如下：

   -- create partitions on disk drives (type 8e in fdsik)
   -- create physical volumes from the partitions                  --> $ sudo pvcreate /dev/sda1
   -- create the volumes group                                     --> $ sudo vgcreate -s 16m vg /dev/sda1
   -- allocate logical volumes from the volume group               --> $ sudo lvcreate -l 50g -n mylvm vg
   -- format the logical volumes                                   --> $ sudo mkfs -t ext4 /dev/vg/mylvm
   -- mount the logical volumes (also update /etc/fstab as needed) --> $ mkdir /mylvm, 
                                                              then --> $ sudo mount /dev/vg/mylvm /mylvm, 
                                                          then add --> /dev/vg/mylvm /mylvm ext4 defaults 0 0 ( to the /etc/fstab)
