I agree with David. If there is no present way to recover unused InnoDB tablespace, then we (as a community) seriously need to create a tool to do just that. How have we gone so long without it? I always assumed it was possible (I guess I have been just lucky enough to not need to do it yet....)
What if, during the course of a major data import, I try something that creates a working table that expands my datafile to fill my available disk space. I might have made a logical error or not. Regardless of why it filled up, without the ability to reclaim that room, an entire server could be royally scr***d (assuming a server that supports a mix of InnoDB and other table types). Please tell me there is something other than a dump-delete-import that can be used to shrink InnoDB tablespaces.
