Virtualbox 虛擬機擴容，解決 Low disk space on “Filesystem root”問題

問題描述

創建虛擬機時，選擇的硬盤空間小，隨着使用內存空間占用變得變少，進入虛擬機，會提醒“Low disk space on “Filesystem root””

解決方法^[1]

1. Open cmd as administrator.
2. Go to the folder where the VirtualBox is installed so you can use the VBoxManage program.
3. From there, run the following command:

VBoxManage modifyhd <file path and name> --resize <size in MB>
e.g.: VBoxManage modifyhd C:\V-MACHINES\SERVER2008\WIN-2008.VDI --resize 26000

<file path and name> 可以在 Virtual box 設置中找到

4. You will see a message from 0 to 100% and done.

5. Start your machine and go to "Computer" (or "My Computer", if applicable), right click and select "Manage", go to "Storage" → "Disk Management", right click on the disk you want to expand, click on "Extend Volume" and resize the disk as you wish.
   

6. If necessary restart the VM.
