一台伺服器,普通/dev/sda1/2(硬碟一) 同步資料到 lvm_member(硬碟二)
rsync兩硬碟資料同步:
From: http://hi.baidu.com/williwill/item/7a36fdd92340b2ee55347f13
系統啟動到request_module: runaway loop modprobe binfmt-464c掛起
利用隨身碟系統,掛載硬碟出現:mount: unknown filesystem type ‘LVM2_member‘
解決辦法:
需要安裝 lvm2: yum install lvm2
然後按一下步驟:
1、查看物理卷:pvs
PV VG Fmt Attr PSize PFree
/dev/sda2 VolGroup00 lvm2 a- 279.22G 32.00M
2、查看卷組: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
--- 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、如未啟用,需要啟用邏輯卷:vgchange -ay /dev/VolGroup00
LV Status available
5、掛載邏輯卷:mount /dev/VolGroup00/LogVol03 /home/lvm
mount: unknown filesystem type 'LVM2_member'解決方案【轉】
