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.
