The solution involves "changelog crash consistency" among other things. 
Since this feature itself is targeted for glusterfs-3.7, I would say the 
complete solution would be available with glusterfs-3.7

One the major challenges in solving it involves ordering/sequencing the 
fops that happen on the master volume. Because of the distributed nature 
of glusterfs and geo-rep, coordinating between gsyncds for proper 
ordering of fops is hard.

I have cc'd Aravinda who is the maintainer of geo-rep. He would have 
more details.
