LVM 在 RHEL6 中显示为单独的分区

当我在硬盘上创建逻辑卷时，新分区显示在 fdisk -l 输出中。

[root@linux1 ~]# fdisk -l

请帮我如何禁止将逻辑卷显示为单独的硬盘，否则如果我们有更多的硬盘和更多的 LVM，就会产生混乱。

我不想"/dev/mapper/vg_linux1-lv_root"在 fdisk -l 输出中看到 LV 磁盘。如果有任何配置更改可以实现这一点，请告诉我。

fdisk按照设计运行，即使设计明显有问题。

从手册页中：

       -l     List the partition tables for the  specified  devices  and  then
              exit.   If no devices are given, those mentioned in /proc/parti‐
              tions (if that exists) are used.

要解决此问题，请明确指定要使用的磁盘。例如：

fdisk -l /dev/sd?
