        Hi Uma. It looks like this patch includes hard tab characters. Our coding standard is to indent with two spaces. Can you please fix?

        Since it looks like you plan to be a frequent contributor, I would suggest setting up your editor of choice to have the right formatting rules.

        Hi Uma. Now that I look at this patch again, I realize that it doesn't quite do what I would expect. It ends up including the available size of the last volume checked, but that's not necessarily the volume with the most free space.

        Instead, I think we should keep track of a maxAvailable variable, and then have the exception read "Insufficient space for an additional block. Volume with the most available space has N bytes free, configured block size is M."

        Sorry that I didn't notice this in the earlier review.

        What do you think?
