解决办法：
需要安装 lvm2: yum install lvm2
然后按一下步骤：
1、查看物理卷：pvs
PV VG Fmt Attr PSize PFree
/dev/sda2 VolGroup00 lvm2 a- 279.22G 32.00M
2、查看卷组：vgs
VG #PV #LV #SN Attr VSize VFree
VolGroup00 1 4 0 wz--n- 279.22G 32.00M
3、查看逻辑卷：lvdisplay
--- Logical volume ---
LV Name /dev/VolGroup00/LogVol03
VG Name VolGroup00
LV UUID YhG8Fu-ZGPk-qt8D-AxgC-DzOU-dg1F-z71feI
