Okey, maybe this will be a bit technical, but it worth if you want to mount a lvm volume to a linux system.
in my case, there is hard disk which i want to look inside but unfortunately its still on lvm volume and i had a suprised that i can't just mount it to linux system.
#fdisk -l /dev/hdd
Disk /dev/hdd: 10.2 GB, 10242892800 bytes
255 heads, 63 sectors/track, 1245 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hdd1 * 1 13 104391 83 Linux
/dev/hdd2 14 1245 9896040 8e Linux LVM
its clear that /dev/hdd2 is linux LVM which i want to mount.
now we use pvs to determined the volume group!
#pvs
PV VG Fmt Attr PSize PFree
/dev/hda2 VolGroup00 lvm2 a- 38,06G 32,00M
and to find out what device it will mount to system, we use:
lvdisplay /dev/VolGroup00
— Logical volume —
LV Name /dev/VolGroup00/LogVol00
VG Name VolGroup00
LV UUID OaGyCv-UkUn-IFL1-xEd8-V3mJ-IG85-XMChWW
LV Write Access read/write
LV Status available
# open 1
LV Size 37,03 GB
Current LE 1185
Segments 1
Allocation inherit
Read ahead sectors 0
Block device 253:0
— Logical volume —
LV Name /dev/VolGroup00/LogVol01
VG Name VolGroup00
LV UUID x7itWw-eS0L-kjV7-72Fl-pTZX-fSKl-AqxxjX
LV Write Access read/write
LV Status available
# open 1
LV Size 1,00 GB
Current LE 32
Segments 1
Allocation inherit
Read ahead sectors 0
Block device 253:1
and that's it. the device is at /dev/VolGroup00/LogVol00, now let just mount it to system.
mount /dev/VolGroup00/LogVol00 /mnt/hd
done.
