查看同一个LUN的多个分区

任何人都知道为什么我看到多个设备为同一个LUN？我检查了存储组他们只暴露了360000970000196801239533036304532这台服务器，但为什么我看到这些很多分区（p1..p7）

lrwxrwxrwx 1 root root 8 Jan 20 16:30 360000970000196801239533036304532 -> ../dm-39 lrwxrwxrwx 1 root root 8 Jan 20 16:30 360000970000196801239533036304532p1 -> ../dm-64 lrwxrwxrwx 1 root root 8 Jan 20 16:30 360000970000196801239533036304532p2 -> ../dm-65 lrwxrwxrwx 1 root root 8 Jan 20 16:30 360000970000196801239533036304532p3 -> ../dm-66 lrwxrwxrwx 1 root root 8 Jan 20 16:30 360000970000196801239533036304532p4 -> ../dm-67 lrwxrwxrwx 1 root root 8 Jan 20 16:30 360000970000196801239533036304532p5 -> ../dm-69 lrwxrwxrwx 1 root root 8 Jan 20 16:30 360000970000196801239533036304532p6 -> ../dm-70 lrwxrwxrwx 1 root root 8 Jan 20 16:30 360000970000196801239533036304532p7 -> ../dm-71 

AFAIK我知道dev映射器中的设备是在引导过程早期创build的，/ dev / dm-n仅供内部使用

即使在fdisk的输出，我看到这2个设备

当我尝试在原始LUN上创build物理卷时，由于此错误而失败

 pvcreate /dev/mapper/360000970000196801239533036304532 Device /dev/mapper/360000970000196801239533036304532 not found (or ignored by filtering). 

我已经检查过lvm.conf，没有定义过滤
