I'm trying to extend the disk space on the root partition of my ubuntu VM from 1.5TB to 3.4TB. I thought this would be an easy task but I'm having a hard time figuring out how to do this on an OS level. The console outputs below explain my current setup (nothing fancy, just one partition with a large amount of storage):
root@ubuntu-samba:/home/joel# fdisk -l

Question:
How do I extend the physical volume '/dev/sda5' to use 100% of '/dev/sda's storage (3.4TB)?
I've done a lot of playing around but getting nowhere.
A lot of online tutorials claim it's as simple as extending the logical volume, but that's not working for me as the additional storage isn't detected.
lvextend -L +100%FREE /dev/mapper/ubuntu--samba--vg-root
New size (383110 extents) matches existing size (383110 extents)
Any pointers would be greatly appreciated as I've wasted days on this and am desperate for additional storage :(

The lvextend is not applicable as the volume group first has to be resized.
1) Resize the partition /dev/sda2 in fdisk to the maximum cylinders/sectors available.
2) Then resize /dev/sda5 accordingly.
3) Then this command should do the trick: pvresize /dev/sda5
Check with command "vgs" the status of the volume group afterwards.
Alternatively create /dev/sda6 in fdisk to take up the rest of the device, also of type "Linux LVM". Then add the new physical volume: pvcreate /dev/sda6
Again: Check with "vgs" the status of the volume group afterwards.
Did you create the
/dev/sda5partition ?
