系统启动到request_module: runaway loop modprobe binfmt-464c挂起
利用U盘系统，挂载硬盘出现：mount: unknown filesystem type 'LVM2_member'
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 VFreeVolGroup00 1 4 0 wz--n- 279.22G 32.00M
3、查看逻辑卷：lvdisplay
--- Logical volume ---LV Name/dev/VolGroup00/LogVol03VG NameVolGroup00LV UUIDYhG8Fu-ZGPk-qt8D-AxgC-DzOU-dg1F-z71feILV Write Access read/writeLV Statusunenable# open1LV Size245.97 GBCurrent LE 7871Segments1Allocation inheritRead ahead sectors auto- currently set to 256Block device 253:2
4、如未激活，需要激活逻辑卷：
vgchange -ay /dev/VolGroup00LV Statusavailable
5、挂载逻辑卷：
mount /dev/VolGroup00/LogVol03 /home/lvm
