This was a while back. I was hosting a site at a hosting company's 'vps'. I had 1gig for the mysql databases. Problem is, for some reason the server didnt let me have more than 300mbs including everything (there were some videos on the site). I contacted them and they only replied that its ok on their end. Okay, makes sense. So i opened ssh and started looking for the problem. After a bit, i figured out that my site is hosted on a 1tb drive and i could see all the other partitions. Meaning they just slapped a bunch of users data on the same drive. So i wrote an assembly program to offset the mysql files by ~500 mbs. Turns out that put me in an unoccupied 100gb partition and the site was still working properly. So i offset everything to there and i had a 100gb vps for like $5.
