- Vagrant
- Virtualbox
- CentOS 7
The following steps are based on a Vagrant VM box which does NOT use LVM for a root partition, which seems to be the case for the official CentOS box.
$ vagrant plugin install vagrant-disksize
Add the following line to Vagrantfile
# Every Vagrant development environment requires a box. You can search for
# boxes at https://vagrantcloud.com/search.
config.vm.box = "centos-VAGRANTSLASH-7"
config.disksize.size = '250GB' # <- Add this line to increase from 40GB to 250GB, for instance
Restart the VM and run the following commands.
[vagrant@localhost ~]$ sudo su -

Welcome to fdisk (util-linux 2.23.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Now you have additional 226GB in a new partition (/mariadb-data). Note that you need to specify a right UUID in /etc/fstab which you can obtain from blkid command.
