[Linux]-Virtualbox-centos dynamic increase of partition space method

VirtualBox in use, sometimes because of the lack of allocated space caused problems, you can use the following ways to increase the partition space:

First, VirtualBox settings:

1) go to VirtualBox's installation directory to find this command EXE file: Vboxmanage.exe

2) Run command: vboxmanage modifyhd centos_sp.vdi--resize 100000

Resets the virtual machine size to 100G

If you re-mount the existing virtual machine VDI, there will be a problem with the UUID, and the workaround is to use the command:

" F:\VM\CentOS_SP.vdi "

Second, the CentOS setup:

1) Use Fdisk to add space:

fdisk/dev/SDANP3tW

N: New partition, P: Primary partition, 3: Can enter directly, T: also direct return, W: Write

2) Continue the command:

/dev//dev/-L+100g/dev/centos//dev/centos/root

3) View the completed partition space:

DF -hl
