Hi Mark,

this looks like a rather usual Ubuntu VM behaviour! I run in to it a number of times, and I'm not sure why this is happening.

50GB VM drive, install Ubuntu to use the entire space with LVM and that's what you are getting..

Word of warning, resizing live root folder can damage your system :) but we all know that already, so a VM snapshot will be a great help here.

I don't have access to my notes right now but one of those links will sort this out:

https://kb.vander.host/operating-systems/how-to-resize-an-ubuntu-18-04-lvm-disk/

Hope that helps..

Can anyone explain this?

$ sudo fdisk -l /dev/sda
Disk /dev/sda: 50 GiB, 53687091200 bytes, 104857600 sectors
Disk model: VBOX HARDDISK
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

$ df -h .

/dev/mapper/ubuntu--vg-ubuntu--lv 24G 23G 13M 100% /

The scenario is that this is a new VirtualBox VM with Ubuntu 20.04.4
installed. It has a single 50GB disk as shown in VirtualBox and fdisk,
but having copied 23GB to it from elsewhere (using rsync) the disk is
now full.
What am I missing and how do I get my disk space back?
