Seems my (Ubuntu 16.04) running on (Ubuntu 16.04) Linux host as a virtual maschine with dynamic file size for vdi runs out of space, maybe see:

/home/dirk/.Private          5,4G    5,1G     0  100% /home/dirk

On the host is enough free space that vdi can expand, maybe see:

I am wondering if LVM has quit his service to fit the vm dynamic to the physical drive? How further to investigate this isse I (my server) ran in?

  • maybe askubuntu.com/questions/32499/… will help you – Yoran Jansen May 13 '18 at 9:53
  • I like to understand it. The link seems to show how to convert a physical into virtual. – Dirk Lehmann May 13 '18 at 9:56
  • Or other way around the link shows how to convert virtual to physical. I prefere to use my virtual further and to fix the guest or host that the pysical free disk space is used by the vm. – Dirk Lehmann May 13 '18 at 9:59
  • So you want to grow your vm? I am not sure what you mean, sorry. – Yoran Jansen May 13 '18 at 15:54
  • Maybe try this, askubuntu.com/questions/32499/… , and go to the first answer. That one is confirmed by the asker – Yoran Jansen May 13 '18 at 15:55

  1. Delete all snapshots of the vm running out of diskspace that you just have on current state and one vdi file

  2. Resize the vdi from initial size to a size you like and can with

VBoxManage modifymedium /home/user/vm/server.vdi --resize x (where x is the desired new total space in megabytes)

  1. Boot VM with GParted ISO-Image and fit logical volumen of the vm to the new size.

  2. Boot VM Ubuntu OS and do

sudo lvresize -L xx.xxG /dev/ubuntu-tt-vg/root

and

sudo resize2fs /dev/ubuntu-tt-vg/root xxxxxxx (where x are the number of blocks)

(might be that the path looks other than /dev/ubuntu-tt-vg/root for example /dev/mapper/ubuntu--vg-root, figure that therefor out with fdisk -l)
