There are some bugs filed that sound like the problem you are seeing:

Bug 910836 - peer probe over ipv6 on ipv4/ipv6 network fails.
Bug 922801 - Gluster not resolving hosts with IPv6 only lookups
Bug 1070685 - glusterfs ipv6 functionality not working

If you have additional information on issue, it'll be appreciated if you 
can add that. In case you have also noticed a different problem, please 
create a new bug for it.

Some issues look relatively easy to solve. If that is indeed the case, 
don't hesitate to send patches. Of course, you're also welcome to send 
patches for complex bugs ;-)

Thanks,
Niels
