How to mount a LVM partition on Ubuntu?

#fdisk -l

/dev/sdb1   *           1        9702    77931283+  8e  Linux LVM

I tried the following command:

#mkdir /media/backup
#mount /dev/sdb1 /media/backup

mount: unknown file system 'LVM2_member'

How do I mount it?

Solution 1:

I found the solution

#pvs
/dev/sdc5 intranet lvm2 a- 372,37G 0

# lvdisplay /dev/intranet
LV Name                /dev/intranet/root

#mount /dev/intranet/root /media/backup

Solution 2:

You probably want to look at the *scan commands, pvscan, vgscan and lvscan. This will search for the various lvm components. If /dev/sdb1 is a physical volume that has a volume group with a logical volume, it should show up. If lvscan produces something like:

ACTIVE '/dev/vg00/home' [9.00 GB] inherit

Then you can mount /dev/vg00/home as /home.
