What is LVM Partition?

LVM stands for Logical Volume Manager and is a flexible storage management system available on Ubuntu and many other Linux distributions. You can manage disk partitions, volumes, and file systems in a more dynamic and flexible way compared to traditional partitioning schemes using LVM. It is an advanced method than the traditional method of partitioning a disk into one or more sectors and formatting that partition with a file system.

Resizing LVM Partition on Ubuntu VPS

In the first step, you should collect information about current LVM settings and names. To do this, find out the physical volumes that are used by the LVM file system using the command below:

sudo pvs

And run the command below to find out the Volume group name:

sudo vgdisplay

Now you can get information about the Logical Volume as shown below:

sudo lvdisplay

Note that you need to insert the new virtual or physical disk. Once done, configure the inserted disk within the existing LVM file system.
Then identify the new disk using the command below:

sudo fdisk -l


sudo lvmdiskscan

Next, create a new disk as Physical Volume on the server as shown below:

sudo pvcreate /dev/vdb

The output should be as follows:

Physical volume “/dev/vdb” successfully created.

Now it’s time to add the new Physical Volume to your existing Logical Volume. To achieve this, simply execute the command provided:

sudo vgextend ubuntu-vg /dev/vdb

The output should look something like this:

Volume group “ubuntu-vg” successfully extended.

And extend the Logical volume using the command below:

sudo lvm lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv

Resize it as shown below:

sudo resize2fs -p /dev/mapper/ubuntu--vg-ubuntu--lv

Lastly, enter the following command to view the correct size of your file system:

df -h

That’s it!
