In the last time on every start of my Ubuntu 14.04 VM I'm getting the message
Low Disk Space
This computer has only 314.8 MB disk space remaining. You may free up some space by emptying the trash.
Now I've increased the disk space from 10
to 20 GB
as described on the VirtualBox forum (first step).
M:\>"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" modifyhd "M:\VM\Ubuntu VM\Ubuntu VM.vdi" --resize 20480
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%
I see, that the disk space has been resized successfully:
But when I start the machine and open GParted, only 10 GB
are available.
So somehow the Ubuntu guest system haven't got the updated information about the disk space.
How to solve it and complete the disk space increase?
