In this blog post, we look into ways to solve the full disk space issue for MySQL running in a Linux-based environment.

With an increase of the usage of solid state drives I/O performance has significantly increased allowing users to push their databases even faster but even then I/O may become a bottleneck and a limiting factor of the performance of the whole database. In this blog post we will take a look at the things you want to check if you notice your I/O performance is high on your MySQL instance.
