VirtualBox 6.1 扩容VDI磁盘容量
确保对应的虚拟机已经关机！！！
Host的VirtualBox端
- 从工具栏管理->虚拟介质管理->虚拟硬盘，找到要修改的硬盘，从下面的大小滑动条修改磁盘大小
根据VirtualBox官网文档的描述，修改完这里之后，对应虚拟机中的容量修改还没生效，需要根据VM中的方式修改，但是官网没给出方式
VM中centos7（linux）的修改
找到你要扩容的物理分区，这里是/dev/sda为例，（文章中内容使用多次扩容结果作为说明，容量暂无法对齐，步骤正确）
- parted /dev/sda 修改物理分区的大小
通过parted工具的print 命令找到要扩容的disk编号，并用
resizepart 2 100%命令进行扩容，然后查看是不是扩容成功
[root@localhost langchain-chat]# parted /dev/sda
GNU Parted 3.1

- 通过lsblk和df命令可以看到，已经扩容到sda disk上了，但是还没有到PV卷上
[root@localhost langchain-chat]# lsblk

- 通过pvresize /dev/sda2对pv卷进行扩容
[root@localhost ~]# pvdisplay

[root@localhost ~]# pvresize /dev/sda2

- 通过lvextend给lvm扩容，扩容后通过df命令可以看到根分区容量已经到我们需要的大小
[root@localhost ~]# lvextend -l +100%FREE --resizefs /dev/mapper/centos-root
Size of logical volume centos/root changed from <196.00 GiB (50175 extents) to <296.00 GiB (75775 extents).
Logical volume centos/root successfully resized.
