# Expanding LVM to Full Capacity

<p>After building a PC and installing Ubuntu, I noticed that the logical partition in LVM was not utilizing the entire storage capacity, so I decided to extend it.</p>
<p></p>
<pre>$ df -h<br />Filesystem                         Size  Used Avail Use% Mounted on<br />udev                                16G     0   16G   0% /dev<br />tmpfs                              3.2G  1.8M  3.2G   1% /run<br />/dev/mapper/ubuntu--vg-ubuntu--lv  <span style="color: #ff0000;">196G</span>   75G  112G  41% /</pre>
<p>Even though I was using 1TB of storage, only a 196GB partition was created.</p>
<p></p>
<pre>$ lsblk<br />NAME                      MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT<br />...<br />nvme0n1                   259:0    0 931.5G  0 disk<br />├─nvme0n1p1               259:1    0     1M  0 part<br />├─nvme0n1p2               259:2    0     1G  0 part /boot<br />└─nvme0n1p3               259:3    0 930.5G  0 part<br />  └─ubuntu--vg-ubuntu--lv 253:0    0   <span style="color: #ff0000;">200G</span>  0 lvm  /</pre>
<p>The physical partition is 930GB, but the logical partition is 200GB.</p>
<p></p>
<p>Use <code>lvextend -l +100%FREE</code> to extend it to the maximum capacity.</p>
<pre>$ lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv<br /> Size of logical volume ubuntu-vg/ubuntu-lv changed from 200.00 GiB (51200 extents) to &lt;930.51 GiB (238210 extents).<br /> Logical volume ubuntu-vg/ubuntu-lv successfully resized.<br />$ lsblk<br />NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT<br />...<br />nvme0n1 259:0 0 931.5G 0 disk<br />├─nvme0n1p1 259:1 0 1M 0 part<br />├─nvme0n1p2 259:2 0 1G 0 part /boot<br />└─nvme0n1p3 259:3 0 930.5G 0 part<br /> └─ubuntu--vg-ubuntu--lv 253:0 0 <span style="color: #ff0000;">930.5G</span> 0 lvm /</pre>
<p>It has been extended.</p>
<p></p>
<pre>$ df -h<br />Filesystem                         Size  Used Avail Use% Mounted on<br />udev                                16G     0   16G   0% /dev<br />tmpfs                              3.2G  1.8M  3.2G   1% /run<br />/dev/mapper/ubuntu--vg-ubuntu--lv  <span style="color: #ff0000;">196G</span>   75G  112G  41% /</pre>
<p>Since it has not yet been reflected in the file system, proceed with resize2fs.</p>

<p>It has been extended.</p>

<h2>Note: For Non-LVM Partitions</h2>
<p>Memo for cases when extending EBS on EC2. For non-LVM partitions.</p>
<p>Case of extending EBS from 100GB to 200GB. Since it's not LVM, <code>lvextend</code> cannot be used. Instead, use <code>growpart</code>.</p>
