系統啟動到request_module: runaway loop modprobe binfmt-464c掛起
利用U盤系統，掛載硬盤出現：mount: unknown filesystem type 'LVM2_member'
解決辦法：
需要安裝 lvm2: yum install lvm2
然后按一下步驟：
1、查看物理卷：pvs
PV VG Fmt Attr PSize PFree
/dev/sda2 VolGroup00 lvm2 a- 279.22G 32.00M
2、查看卷組：vgs
VG #PV #LV #SN Attr VSize VFree
VolGroup00 1 4 0 wz--n- 279.22G 32.00M
3、查看邏輯卷：lvdisplay
--- Logical volume ---
LV Name /dev/VolGroup00/LogVol03
VG Name VolGroup00
LV UUID YhG8Fu-ZGPk-qt8D-AxgC-DzOU-dg1F-z71feI
LV Write Access read/write
LV Status unenable
# open 1
LV Size 245.97 GB
Current LE 7871
Segments 1
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 253:2
4、如未激活，需要激活邏輯卷：vgchange -ay /dev/VolGroup00
LV Status available
5、掛載邏輯卷：mount /dev/VolGroup00/LogVol03 /home/lvm
