1.关闭要扩容的lxc虚拟机
2.进入pve的shell
bash
#安装必要软件, CTid=101 的LXC 为例
apt install guestfs-tools
cd /var/lib/vz/images/101/
#备份已有数据
cp vm-101-disk-0.raw vm-101.bak
#查看raw 磁盘情况
virt-df -h vm-101-disk-0.raw
#执行结果：
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

#查看调整后的磁盘情况
virt-df -h vm-101-disk-0.raw
#执行结果
