Hey, I have an issue with an Ubuntu VM that ended up with a completely full disk, I've expanded the drive in HyperV and using the Ubuntu live CD I was able to use fdisk and growpart to expand the partition, however I'm stuck at the stage of using lvextend, the live environment seems to have no visibility of the logical volume so I can't use the command.

You can scan the volume groups, and physical volumes with like vgs pvs (maybe there was an explicit scan command too) to see what is there, and you can activate a volume group with vgchange too, so that it shows up
