The default capacity of vagrant CentOS 7.2 box is only 8G

8G?!

What can be done? This capacity will be full in a few weeks. Maybe it's for the sake of portability, but as a developer who wants to build various development environments on vagrant, the capacity of 8G can only make vagrant a chicken.

Fortunately, there are gods on the Internet who summarize how to expand the capacity of vagrant. The following is the actual operation process after I refer to the tutorial, and the capacity has been expanded to 800G, which can be used for personal test!

Preparation stage

• Shut down virtual machine

☁  centos  vagrant halt

• Transform mirroring

☁  centos  cd ~/VirtualBox\ VMs/centos_default_1533259579120_24934
☁  centos_default_1533259579120_24934  VBoxManage clonehd "centos-vm-disk1.vmdk" "clone-disk1.vdi" --format vdi

• Extended mirroring

☁  centos_default_1533259579120_24934  VBoxManage modifyhd "clone-disk1.vdi" --resize 819200 # Expand to 800G

• Remount the disk to the virtual machine and start the virtual machine

☁  centos_default_1533259579120_24934  VBoxManage storageattach centos_default_1533259579120_24934 --storagectl "SATA Controller" --port 0 --device 0 --type hdd --medium clone-disk1.vdi
☁  centos  vagrant up # Turn on virtual machine
☁  centos  vagrant ssh # Enter virtual machine

Capacity expansion in virtual machine

• View and format the disk

➜  ~ sudo fdisk -l
➜  ~ sudo fdisk /dev/sda
# Press p to display the partition table. The default values are sda1 and sda2.
# Press n to create a new primary partition.
# Press p to set the primary partition.
# Input 3 is set to the third partition.
# Enter two carriage returns to set the default disk start location.
# Enter t to change the partition format
# Enter 3 to select the third partition
# Input 8e format to LVM format
# Enter w to execute

• Restart virtual machine

➜  ~ sudo reboot

• Create physical volume

➜  ~ sudo pvcreate /dev/sda3

• View volume groups and expand to corresponding volume groups

➜  ~ sudo vgdisplay
➜  ~ sudo vgextend centos /dev/sda3

• Expand to the appropriate logical volume

➜  ~ sudo lvextend -l +100%FREE  /dev/mapper/centos-root

• Update file system

➜  ~ sudo xfs_growfs /dev/mapper/centos-root

Be accomplished

So far, the extension is successful

➜  ~ df -h
Filesystem               Size  Used Avail Use% Mounted on

none                     112G   81G   32G  72% /vagrant
tmpfs                     62M     0   62M   0% /run/user/1000

Back to the physical host, you can delete the original image

☁  centos_default_1533259579120_24934  rm -f centos-vm-disk1.vmdk
