BTRFS

Due according to date on Canvas

Assignment

On an AWS EC2 (ubuntu 18.04) instance. Attach at least 4 1G volumes to an ec2 instance.

details

• Add all these volumes to a btrfs filesystem in a RAID5 configuration. Create a subvolume called web. Mount the subvolume to /web
• Install apache (apt update, apt install apache2) and snapper.

• By default apache tries to host pages out of /var/www/html. You should change it to host out of /web. The easiest way to do this is to cd to /var/www, then rm -rf html, then ln -s /web html. You should then restart the apache2 service. Create a simple index.html document in your /web directory. Make sure your webpage loads before continuing. (You may also have to edit your security group to allow inbound traffic on port 80.)

• Take a screenshot of your sample webpage.

• Take a pre-snapshot of the web subvolume before you continue. This document might be useful.

• Take a screenshot of the snapper list command.

• Change your website to be some free web template like you might find here

• Take a screenshot of your sample webpage.

• Take a post-snapshot of your web subvolume.

• Take a screenshot of the snapper list command.

• Take a print screen of your rollback command (something like sudo snapper -v undochange 1..2)

• Show that apache loaded your original page.
