Thankfully LVM is flexible enough to extend this partition without causing any huge issues to your operating system. In this writeup, I&rsquo;m gonna extend a 15G volume to a 200G volume on my Ubuntu 22.04.3 LTS VM.</p> <pre tabindex="0"><code>user@ubuntu:~$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS loop0 7:0 0 55M 1 loop /snap/core18/1880 loop1 7:1 0 55.7M 1 loop /snap/core18/2812 loop2 7:2 0 63.9M 1 loop /snap/core20/2105 loop3 7:3 0 74.1M 1 loop /snap/core22/1033 loop4 7:4 0 71.3M 1 loop /snap/lxd/16099 loop5 7:5 0 91.8M 1 loop /snap/lxd/24061 loop6 7:6 0 40.9M 1 loop /snap/snapd/20290 sda 8:0 0 200G 0 disk ├─sda1 8:1 0 1M 0 part ├─sda2 8:2 0 1G 0 part /boot └─sda3 8:3 0 199G 0 part └─ubuntu--vg-ubuntu--lv 253:0 0 15G 0 lvm / sr0 11:0 1 4.5G 0 rom user@ubuntu:~$ df -h Filesystem Size Used Avail Use% Mounted on tmpfs 794M 1.7M 793M 1% /run /dev/mapper/ubuntu--vg-ubuntu--lv 15G 14G 497M 97% / tmpfs 3.9G 0 3.9G 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock /dev/sda2 974M 223M 684M 25% /boot tmpfs 794M 16K 794M 1% /run/user/1000 </code></pre><h2 id="the-fix">The Fix<a href="#the-fix" class="post-heading__anchor" aria-hidden="true">#</a> </h2> <p>First, let&rsquo;s ensure that our physical volume is correctly sized, this command won&rsquo;t really do much if it is, but ts worth running just to be sure.</p>
