The problem here is with the gfid hard links (for providing stable file handles). Index uses hard links from an internal backing file which is also created within .glusterfs - the actual dirty files are never linked into index. While we do want to make index use a different format, it is completely unrelated (in fact not a problem at all) to the XFS quota issue - which is linking of true files into .glusterfs for providing stable file handles.
