[Gluster-users] Thin-arbiter questions

As of now, it is Dec 10th ish.
I guess, the version 7.0 is good to start using thin-arbiter if you just
want to enable it for one cluster. The fixes I made are not mandatory on
v7.0....
I was looking at having just one thin-arbiter for all my clusters, and
hence the proposal to add volume-id etc.
Regards,
Amar
