GFS2: fsck.gfs2 reported statfs error after gfs2_grow
When you do gfs2_grow it failed to take the very last rgrp into account when adding up the new free space due to an off-by-one error. It was not reading the last rgrp from the rindex because of a check for "<=" that should have been "<". Therefore, fsck.gfs2 was finding (and fixing) an error with the system statfs file.
