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 https://askubuntu.com/questions/32499/migrate-from-a-virtual-machine-vm-to-a-physical-system#32505 will help you – Yoran Jansen May 13 '18 at 09:53
  • I like to understand it. The link seems to show how to convert a physical into virtual. – Dirk Lehmann May 13 '18 at 09:56
  • 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 09:59
  • 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, https://askubuntu.com/questions/32499/migrate-from-a-virtual-machine-vm-to-a-physical-system , and go to the first answer. That one is confirmed by the asker – Yoran Jansen May 13 '18 at 15:55
  • Meanwhile I have resized the vdi and resized LVM with GParted, but apt-get upgrade shows me still not enough free space. I have to make a research how to be able to fix it (webserver Apache just shows "error" at the Homepage, Maybe because of inssuficient diskspace). If you might help please tell me with which commands (how-to) see this space for the server. – Dirk Lehmann May 13 '18 at 19:12
  • try lsblk (LiSt BLocK), it shows size for disks and partitions – Yoran Jansen May 14 '18 at 14:54

  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)
