Recently, I archived a project and event that was about 80GB. I created it as a Sparse Bundle and followed the directions as outlined on Ripple. I decided to go back into the project/event and do some messing around.
It was my understanding that a Sparse Bundle would grow in disk size if you added files to it. However, when I was rendering the footage, I got a disk space error. Then, FCP would lock up and I'd force quit. When restarting, I'd get a SAN disk error (I'm not using a SAN). Quitting again and unmounting the Sparse Bundle fixed it. I think there were some other errors, but I didn't log it.
So, does anyone know off hand if I did something wrong or if, perhaps, I'm just wrong about my assumption with Sparse Images? I read about a terminal command for shrinking the images down, if necessary.
