If the system isnt running, surely I wouldnt be able to do anything, so it needs to be online?

Well, you can boot into a Live Linux ISO (Ubuntu or many others) to get to a command shell and do such things with the OS on disk not running. But I think you are fine doing it live after taking a snapshot backup.

@Sebastian-Roth Thanks my friend, snapshot taken in hyper-v and command run… Stupid Q now. How do I check if it’s worked

[Sebastian Roth]

@RogerBrownTDL Reboot and take a look at the disk space with df -h.

i’m guessing /dev/mapper/ubuntu–vg-ubuntu–lv 490G 86G 384G 19% / means its worked?

Nice, that looks great.

Marking as fixed.

@Sebastian-Roth I didn’t know about the 100% option - I like that!
