How to mount LVM partition in Linux

The procedure to mount LVM partition in Linux as follows:

  1. Run vgscan command scans all supported LVM block devices in the system for VGs
  2. Execute vgchange command to activate volume
  3. Type lvs command to get information about logical volumes
  4. Create a mount point using the mkdir command
  5. Mount an LVM volume using sudo mount /dev/mapper/DEVICE /path/to/mount

Let us see all steps in details to mount LVM volume on Ubuntu Linux.

How to mount an LVM volume

Type the following command to find info about LVM devices:
$ sudo vgscan
$ sudo vgscan --mknodes
Scan your Linux system for LVM volumes using vgscan
Above output indicates that I have “fedora_localhost-live” LVM group. To activate it run:
$ sudo vgchange -ay
$ sudo vgchange -ay fedora_localhost-live
Activate the LVM volume using the vgchange command
You can run the following command to list it:
$ sudo lvdisplay
$ sudo lvs
Shows information about available LVM logical volumes
You can get good look at using the ls command:
$ ls -l /dev/fedora_localhost-live/
Sample outputs:

total 0
lrwxrwxrwx 1 root root 7 Aug 17 15:47 home -> ../dm-1
lrwxrwxrwx 1 root root 7 Aug 17 15:47 root -> ../dm-2
lrwxrwxrwx 1 root root 7 Aug 17 15:47 swap -> ../dm-0

Mount an LVM partition

Create a mount point using the mkdir command:
$ sudo mkdir -vp /mnt/fedora/{root,home}
Sample outputs:

mkdir: created directory '/mnt/fedora/root'
mkdir: created directory '/mnt/fedora/home'

Mount both home and root logical volume from LV path using the following syntax:
$ sudo mount {LV_PATH} /path/to/mount/point/
$ sudo mount /dev/fedora_localhost-live/home /mnt/fedora/home
$ sudo mount /dev/fedora_localhost-live/root /mnt/fedora/root

Verify it with the help of df command or grep command:
$ df -T
$ df -T | grep -i fedora
$ ls /mnt/fedora/root
$ ls /mnt/fedora/home

Update /etc/fstab

Update /etc/fstab file if you want a logical volume to be mounted automatically on boot:
/dev/mapper/fedora_localhost--live-root /mnt/fedora/root ext4 defaults 0 0
/dev/mapper/fedora_localhost--live-home /mnt/fedora/home ext4 defaults 0 0
