I have not added any files to the volume so there should be an amount of free space at least as big as the new bricks that were added.  However, it seems as if all the extra space has been taken up with files matching the pattern .*.gfs*.  I presume these are temporary files used for the transfer real files, which should have been renamed once the transfers were completed and verified, and the original versions deleted.  The new bricks contain mostly these temporary files, and zero byte link files pointing to the corresponding real files on other bricks.  An example of such a pair is shown below.

Amar- Thanks for the information and the patch.  The
