I've noticed the space on xvda2 slowly decreasing over the last few months. What could be causing it? None of my projects are that big, so how do I find what is responsible? Here's the command you'll need:
du -sm * | sort -nr | head -15
Just make sure you cd to the desired directory and this command will show you the 15 largest files and directories below your current directory. I started in my root ( cd / ) and followed the largest directory it found each time. In my case it was the ibdata1 file in MySQL that grew to over 2.6 Gb. I had been making lots of structure changes to my databases and it turns out that InnoDB does not reallocate space after you delete a table or modify something. After a few months my 300 Mb worth of databases were taking up almost 3 Gb.
