vagrant centos7 根目录扩容

1 创建 centos7 虚拟机

2 扩容根目录

我知道的扩容方式有两种：1 直接扩容分区；2 扩容逻辑卷。

我没找到为根目录设置到逻辑卷的方法，所以使用直接扩容分区。

1 创建 centos7 虚拟机，

vagrant up

vagrant ssh

查看磁盘大小：

PS E:\workspace\Virtual Machines\vagrant\centos7-138> vagrant ssh
[vagrant@10 ~]$ sudo -i
[root@10 ~]# lsblk
NAME   MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda      8:0    0  40G  0 disk
└─sda1   8:1    0  40G  0 part /
[root@10 ~]#

2 扩容根目录

停止虚拟机 vagrant halt

修改 Vagrantfile，设置磁盘大小为60G

Vagrant.configure("2") do |config|
config.vm.box = "centos/7"
config.disksize.size = "60GB"

注意：需要安装 vagrant-disksize

启动 vagrant up

启动日志中出现

说明设置生效了。

sda1 分区有 40G 的空间，新增的 20 G 不在sda1分区中。

现在要把 20G 的空间加入到 sda1 中。方案就是直接把 sda1 删除，接着重新创建 sda1 分区
