mount: unknown filesystem type 'LVM2_member'解決方案

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:  

centos:
yum install lvm2

ubuntu:
sudo  apt install lvm2

然后按一下步驟：

1、查看物理卷：pvs

pvs
PV       VG       Fmt   Attr PSize PFree 
/dev/sda2   VolGroup00 lvm2 a- 279.22G 32.00M

2、查看卷組：vgs

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

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

vgchange -ay /dev/VolGroup00
LV Status              available

5、掛載邏輯卷：

mount   /dev/VolGroup00/LogVol03   /home/lvm
