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.<br>
