Resize storage in your CodeReady Containers virtual machine

CodeReady Containers (CRC) provides a pre-built development environment based on Red Hat Enterprise Linux and OpenShift Container Platform for quick container-based application development which you can run on your workstation. After installation you can easly configure CRC virtual machine using crc config command to adjust CPU and memory settings according to your needs. However if you would like to resize storage in your CRC virtual machine (which is by default only 30 GB) you'll need to use external tools. Here is how I did it on my RHEL workstation with KVM virtualization using gparted live iso:

1. Increase CRC virtual machine disk size on your host.

For example add additonal 10 GB storage to CRC virtual machine:

$ qemu-img resize ~/.crc/machines/crc/crc +10G

Check actual virtual disk size:

$ qemu-img info ~/.crc/machines/crc/crc | grep 'virtual size'

Now your virtual disk size is increased but you need to resize filesytem inside your CRC Virtual machine.

If you are running CRC 1.6+ it is as easy as:

$ crc start

$ ssh -i /home/jstakun/.crc/machines/crc/id_rsa core@192.168.130.11

$ sudo xfs_growfs /sysroot

$ df -h

If you are running CRC 1.5 or earlier here is my procedure:

2. Download gparted live iso from https://gparted.org/download.php

3. Configure gparted live iso as cd-rom device in you CRC virtual machine

4. Set gparted live iso cd-rom device as first on top in Boot Options

 
5. Boot CRC virtual machine

6. Click 4 times enter until you open gparted GUI as below

7. Select /dev/vda3 partion on the list. Click Resize/Move the selected partition button in the Toolbar on top. Resize partition using unallocated disk space as below

8. Shutdown virtual machine

9. Move gparted live iso cd-rom device down in Boot Options

9. Start your CRC virtual machine with crc start command
 
Now you can ssh to your CRC virual machine and check that partiton size has been increased!

$ ssh -i ~/.crc/machines/crc/id_rsa core@192.168.130.11
