And then, we need to resize the file system to use the new available space in the logical volume. After that's done, we should make sure that it shows the new disk size. | |||
<syntaxhighlight lang="bash"> | |||
sudo resize2fs /dev/ubuntu-vg/ubuntu-lv | |||
df -h | |||
</syntaxhighlight> | |||
Next, let's get the latest updates for the server and remove any space wasters. | |||
<syntaxhighlight lang="bash"> | |||
sudo apt update && sudo apt -y upgrade && sudo apt -y autoremove | |||
</syntaxhighlight> | |||
Now we need to configure the timezone and our charset. If you want to enable unattended upgrades, now is a good time to do that as well. | |||
< | <syntaxhighlight lang="bash"> | ||
sudo dpkg-reconfigure tzdata && locale-gen en_US.UTF-8 && dpkg-reconfigure locales && dpkg-reconfigure -plow unattended-upgrades | |||
