簡單修復邏輯卷一例ide
mount: unknown filesystem type 'LVM2_member'解決方案oop
系統啓動到request_module: runaway loop modprobe binfmt-464c掛起spa
利用U盤系統,掛載硬盤出現:mount: unknown filesystem type 'LVM2_member'qt
解決辦法:it
須要安裝 lvm2: io
# yum install lvm2class
而後按一下步驟:module
一、查看物理卷:file
#pvsrequest
PV VG Fmt Attr PSize PFree
/dev/sda2 VolGroup00 lvm2 a- 279.22G 32.00M
二、查看卷組:
# vgs
VG #PV #LV #SN Attr VSize VFree
VolGroup00 1 4 0 wz--n- 279.22G 32.00M
三、查看邏輯卷:
# 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
四、如未激活,須要激活邏輯卷:
# vgchange -ay /dev/VolGroup00
LV Status available
五、掛載邏輯卷:mount /dev/VolGroup00/LogVol03 /mnt
掛載時出現mount: Structure needs cleaning
修復邏輯卷組
# xfs_repair -L /dev/vgcb0
#mount /dev/VolGroup00/LogVol03 /mnt
