The 'xattrop-6fa...' is the base entry. gfids of files that need heal 
are hard linked to this entry, so nothing needs to be done for it. But 
you need to find out why '29e0d13...' is not healing. Launch the heal 
and observe the glustershd logs for errors. I suppose the inode number 
for .glusterfs/29/e0/29e0d13e-1217-41cc-9bda-1fbbf781c397 is what is 
8394642.  Is .glusterfs/29/e0/29e0d13e-1217-41cc-9bda-1fbbf781c397 a 
regular file or  symlink? Does it exist in the other 2 bricks? What is 
the link count (as seen from stat <file>)?
