#克隆磁盘
cd C:\Program Files\Oracle\VirtualBox\
VBoxManage.exe clonehd "C:\Users\Administrator\VirtualBox VMs\centos7\centos7.vdi" "C:\Users\Administrator\VirtualBox VMs\centos7\centos60G.vdi" --existing

发现磁盘已经识别新容量了.
fdisk 利用未分区的容量新建一个分区 sda3 40g
lvm
扩展vg
vgextend cl /dev/sda3
扩展lv(设置新容量)
lvextend -L +50G /dev/cl/root 
扩展文件系统
