Our other database host for Universeodon is sitting at a bit over 80% disk usage, and we have one of our more general purpose application servers running at 80% and another at over 90% as well.
This means I'm starting to have to look at if the current scale we are running the site at is sustainable (For both here and Universeodon) and if reducing the amount of servers we have is going to be the only real option forward so we can invest in a larger capacity server for our DB's.
