Thanks, noted. One more query. Are there files inside each of these 
directories? Or is it just empty directories?

symlinks are only for dirs. For files, they would be hard links to the 
actual files. So if stat 
../brick/.glusterfs/aa/e4/aae4098a-1a71-4155-9cc9-e564b89957cf gives you 
a file, then you can use find -samefile to get the other hardlinks like so:
#cd /brick/.glusterfs/aa/e4/aae4098a-1a71-4155-9cc9-e564b89957cf
#find /brick -samefile aae4098a-1a71-4155-9cc9-e564b89957cf

If it is a hardlink, then you can do a getfattr on 
/brick/.glusterfs/aa/e4/aae4098a-1a71-4155-9cc9-e564b89957cf itself.
