LVM底层磁盘丢失，查看lvm设置报错，解决方法

做了一个Lvm逻辑卷，由三个物理磁盘分区组成，一天不小心把一块物理分区删除了，接下来lvdisplay和vgdisplay都出现如下错误提示：
[root@centos-wang ~]# lvdisplay
  Couldn't find device with uuid WZtJhn-ZXkw-F2SZ-vJLp-hkyf-omsT-oY719z.
  Couldn't find device with uuid 9yV24H-RlIL-mMhQ-FZ9j-IY0d-2bP8-qi6KRS.
[root@centos-wang ~]# vgdisplay
  Couldn't find device with uuid WZtJhn-ZXkw-F2SZ-vJLp-hkyf-omsT-oY719z.
  Couldn't find device with uuid 9yV24H-RlIL-mMhQ-FZ9j-IY0d-2bP8-qi6KRS.
  --- Volume group ---
  VG Name               vbirdvg
  System ID

  Metadata Sequence No  5
  VG Access             read/write
  VG Status             resizable

  Cur LV                0

  Max PV                0
  Cur PV                3
  Act PV                1
  VG Size               5.12 GiB
  PE Size               32.00 MiB
  Total PE              164
  Alloc PE / Size       0 / 0   
  Free  PE / Size       164 / 5.12 GiB
  VG UUID               BW5mQ2-BDaE-IgFd-GEnr-a2SU-TqfA-G5wyvn

解决办法就是：
vgreduce --removemissing  VolGroup00


[root@centos-wang ~]# vgreduce --removemissing vbirdvg
  Couldn't find device with uuid WZtJhn-ZXkw-F2SZ-vJLp-hkyf-omsT-oY719z.
  Couldn't find device with uuid 9yV24H-RlIL-mMhQ-FZ9j-IY0d-2bP8-qi6KRS.
  Wrote out consistent volume group vbirdvg
[root@centos-wang ~]# vgdisplay
