I created a .vdi with fixed disk size and later resized the disk size and attached to my Linux VM. But still my VM is not updated with the resized disk

Initially i got an error during the resize “Resize hard disk operation for this format is not implemented yet!” , maybe because I was trying to resize a fixed size disk

So I first created a clone of the existing virtual hard drive via Command Prompt, as it creates "dynamically allocated virtual hard drive" so that I can resize it without any errors

enter image description here

Then resized the cloned vdi to 40GB: enter image description here

Then attached my resized vdi to VirtualBox and removed my old vdi: enter image description here I see that my disk size is resized here on the GUI.

But now when I run my VM, I still see that my disk size remains the same and not updated. enter image description here

Any inputs on how I can update my VM with the resized disk will be helpful. Thanks

As in: http://manpages.ubuntu.com/manpages/bionic/man8/lvextend.8.html

Extend the size of an LV by 54MiB, using a specific PV.

$ lvextend -L +54 vg01/lvol10 /dev/sdk3

Extend the size of an LV by the amount of free space on PV /dev/sdk3. This is equivalent to specifying "-l +100%PVS" on the command line.

$ lvextend vg01/lvol01 /dev/sdk3

Extend an LV by 16MiB using specific physical extents.

$ lvextend -L+16m vg01/lvol01 /dev/sda:8-9 /dev/sdb:8-9

Was able to resolve this using GParted to modify the Linux native partition
