mount unknow filesystem type lvm2_member
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。
