df -T -h当我使用、parted ... print和 时，为什么在 CentOS 7 安装过程中创建的 DATA 分区的图片不一致/冲突fdisk -l？ 如果重要的话，请使用 xfs 文件系统，因为这是默认的。
该过程的背景是：
在最近安装 CentOS 7 的过程中，我在安装目标部分选择了手动分区。 这个链接里的教程包含说明安装过程的屏幕截图，创建 DATA 分区的过程中的屏幕如下所示（来自同一教程）。
（来源：howtoing.com）
在上面的屏幕截图中，我的安装向导自动创建了一个/homeDATA 分区。我缩小了自动创建的分区，并使用屏幕截图中显示的屏幕/home创建了四个新的 300 GB DATA 分区，名为/public、/vpn、/data、 ，然后完成了安装。/test
df -T -h结果：
在最终的安装中，键入df -T -h结果：
[root@localhost ~]# df -T -h

**parted ... quit结果：
然而parted似乎并没有看到这四个新的DATA分区，如下图：
[root@localhost ~]# parted
GNU Parted 3.1

fdisk -l结果：
结果似乎是上面显示的和结果fdisk -l的混合，但这里将四个新分区视为一个单独的类别： parteddf

(parted) quit
答案1
您似乎选择使用逻辑卷 (LVM) 而不是分区。这些不是分区，并且使用不同的机制进行管理。
尝试使用 LVM 命令，例如sudo lvm lvs.这应该列出逻辑卷。
