Anticipating Disk Growth

Adrian Buckman has a script which gives you an idea of what would happen if your databases all grew by some factor overnight:

The other day I got thinking about what would happen if all databases on a single instance grew out, every single one of them! but not just once, what if they all grew out three, four or fives times overnight – what would things look like?

Well I know the likelihood may be slim but wouldn’t it be nice just to see how many times things could grow before it all runs out of space.

I decided for a bit of fun I would write a query to see what the drive space would look like, this would simulate database growth and then show what drive space would be left after the total growths specified.

It’s a good idea to anticipate this kind of activity, though based on the companies I’ve worked for in the past, the answer would be “run out of disk really fast.”
