You can't safely recover from split-brain automatically. Consider;
Node A saved a Fedora ISO, ~3.5GB written.
Node B saved a hours worth of credit card transactions, ~1MB written.
Which node has the more valuable data?
The best you can do is configure and test fencing so that you can avoid
split brain conditions in the first place.
