How to visualize used disk space in your storage pool

Requirements

If you are using PHP 5.3 or earlier: You will need Apache and PHP installed on your Greyhole server to use this script.
With PHP 5.4+, you need nothing.

Install

1. • 0.9.29 or later: No need to install anything. The disk-usage script is now included in all packages.
   • 0.9.28 or earlier: mkdir -p /usr/share/greyhole/web-app/ && curl -o /usr/share/greyhole/web-app/index.php http://bit.ly/ghduphp
2. Make it available through HTTP. For example, you could edit your Apache config to alias /usr/share/greyhole/web-app/index.php.
   If you're using PHP 5.4+, you don't even need a web server. Just start the PHP built-in server, and specify the path to the index.php script: php -S 0.0.0.0:8012 /usr/share/greyhole/web-app/index.php

---

Then simply access the script using your web browser, and you should see a nice visual representation of the disk space used by your files.

If you use php -S, access it at http://your_server_ip_address:8012/

Note that all file copies are counted, so if your Videos share shows as 2TB, and you have num_copies=2 for that share, it means you have 1TB of Videos files x 2 copies = 2TB.
