Hi Jeff,
    Thanks for your response.

For quota code to use SSL, it will need client side certificates as well.
As i mentioned in my original mail.. I was not able to get the gluster
mount w/ SSL to work on the brick node and posted the error log (it says
during SSL connect").

Can you throw some light on that ? My guess is that there is an issue with
the server and client trying to refer to the same set of .key|.pem files but
wanted to validate the same with you.
