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

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

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,需要激活逻辑卷:vgchange -ay /dev/VolGroup00

LV Status available

5、挂载逻辑卷:mount /dev/VolGroup00/LogVol03 /home/lvm
