lvreduce 不接受 lv 路径参数

我正在运行 Ubuntu 22.04.1 LTS。卸载逻辑卷并成功运行 e2fsck 后，lvreduce 失败并出现错误

$ sudo lvdisplay /dev/ubuntu-vg/lv-0
  --- Logical volume ---
  LV Path                /dev/ubuntu-vg/lv-0
  LV Name                lv-0

$ sudo umount /dev/ubuntu-vg/lv-0
$ sudo e2fsck -f /dev/ubuntu-vg/lv-0
$ sudo lvreduce -r -L 512 GB /dev/ubuntu-vg//lv-0 
Command does not accept argument: /dev/ubuntu-vg//lv-0.

删除“512 GB”中的空间后不再出现此错误

$ sudo lvreduce -r -L 512GB /dev/ubuntu-vg/lv-0
