Linux mount an LVM volume / partition command

To mount an LVM volume or partition on Linux, you will first need to have the LVM utilities installed. You can install them using the package manager of your distribution. For example, on Ubuntu, you can use the command sudo apt-get install lvm2.

Once the LVM utilities are installed, you can use the lvdisplay command to list the available LVM volumes. You should be able to see the volume you want to mount in the list.

To mount the LVM volume, you will need to create a mount point. This is a directory where the volume will be mounted. For example, you can create a mount point at /mnt/my_volume.

Then, use the command sudo mount /dev/{volume group}/{logical volume} /mnt/my_volume to mount the volume. Replace {volume group} and {logical volume} with the actual values from the lvdisplay output.

For example, if your volume group is “vg_data” and the logical volume is “lv_data”, the command will look like this:

sudo mount /dev/vg_data/lv_data /mnt/my_volume

It is also worth noting that if you want to mount the LVM partition automatically during boot, you need to add the above command to the /etc/fstab file.

In order to mount an LVM (Logical Volume Management) volume on Linux, you can use the following command:

First, use the lsblk command to check the LVM volume name and path, it will show the volume group name and logical volume name, for example:

lsblk

NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT

sda      8:0    0  100G  0 disk

├─sda1   8:1    0  100G  0 part /

└─sda2   8:2    0    8G  0 part [SWAP]

Use the vgdisplay command to check the volume group name and logical volume name

  VG UUID               g8r1fZ-zUiC-oU6C-U6WQ-1Dd9-9aJZ-8r1fZ

Use the lvdisplay command to check the logical volume name

lvdisplay

  LV Path                /dev/myvg/mylv

  LV Name                mylv

  VG Name                myvg

  LV UUID                g8r1fZ-zUiC-oU6C-U6WQ-1Dd9-9aJZ-8r1fZ

  Block device           253:2

Now use the mount command to mount the volume.

sudo mount /dev/myvg/mylv /mnt

To mount the volume automatically at boot, you need to add the following line to the /etc/fstab file

/dev/myvg/mylv /mnt ext4 defaults 0 0

You can use df -h command to check the mounted volume

df -h
