For resolving gfid-split-brains, there is no automated way or 
favorite-child policy. When you say 2 data+1 arbiter, you are using an 
actual arbiter volume right? (as opposed to a replica 2 volume + a dummy 
node which some people are referring to as arbiter for server-quourm). 
gfid-split-brains should not occur on either replica-3 or arbiter 
volumes with the steps you described.
