mount: unknow filesystem type "LVM2_member"

在使用mount时出现了：mount: unknow filesystem type "LVM2_member"，提示，这说明使用了LVM（logical volume manager）技术，此时可以按照如下操作即可挂载。

1、查看物理卷：pvs

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

2、查看卷组：vgs

#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

#lvdispaly
--- 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

#vgchange -ay /dev/VolGroup00

LV Status              available

5、挂载逻辑卷：mount  LV Name (/dev/VolGroup00/LogVol03 )

#mount   /dev/VolGroup00/LogVol03   /mnt

一般3、4、5步即可。
