     I released a python program 'dirfingerprint' at 
https://github.com/daimh/dirfingerprint/  . We have been using this 
program to get directory stat recursively from each brick node for 
glusterfs filesystem. as it is always slower to access file meta data 
info from gluster filesystem indirectly than brick node directly.

     In our environment, I did the steps below before accessing brick nodes.

1, generate a ssh key, and put it under all brick nodes.

2, ssh to each brick node so '.ssh/known_hosts' has an entry for each node.

3, as all our brick node has the actual data storage mounted under 
/brick, the dirfingerprint command I used is something like

dirfingerprint --gluster-brick=node1:/brick --gluster-brick=node2:/brick 

     Feel free to let me know if you have any questions or suggestions.
