Extended VM Disk In VirtualBox or VMware (虚拟机磁盘扩容)
First, Clean VM all snapshot, and poweroff your VM.
vmdk:
vmware-vdiskmanager -x 16GB myDisk.vmdk
vdi:
VBoxManage modifyhd <absolute path to file> --resize <size in MB>
And now, go to guest OS to resize partition.
I have only one partition, and it's root partition. You can use LiveCD do this. However, You alse use fdisk and resize2fs, that support online mode.
fdisk /dev/sda
Delete old partition, and create new partition you want. Last, write to disk, reboot your VM. Then run:
resize2fs /dev/sda1
Now, you can check your partition size.
df -h
P.S.
I find Shell script on raspi-config. It's a script it is used for expand root filesystem on SD card.
