However, when I needed to resize an image today for my VM at home, I totally forgot about it. Well, this means it&rsquo;s a good excuse for me to just write down a few commands to help me in the future.</p> <p>If you try to follow a long, two things you wanna keep in in mind: do it at your own risk, and always backup your data before you make change to it. Having said, that&rsquo;s get started.</p> https://blog.khmersite.net/p/how-to-expand-qcow2/ Sun, 22 Nov 2020 17:07:50 +1100 https://blog.khmersite.net/p/how-to-expand-qcow2/ <p>Today, one of my VMs needs to have its disk increased. I&rsquo;m using qcow2 as the VM&rsquo;s storage. Here is one way to expand the storage that it&rsquo;s been proven to work very well for me.</p> <p>I already increased this VM&rsquo;s disk to 30GiB once already, but it wasn&rsquo;t enough. So here, let&rsquo;s explode it to 50GiB. The name of the qcow2 file is <code>hosta.qcow2</code>. A friendly reminder that you should alway shave a backup before you perform any critical change such as this one. (I use ZFS, so all I had to do was snapshoting this whole dataset.)</p>
