A split brain is caused by writing to both members while they are disconnected. What in your environment caused that to occur is probably lost in logs a week gone. But, if your procedures always allow only one node (primary) to write to a resource, even if it’s disconnected, then split-brain won’t occur.
“nuke the whole thing” certainly worked. So would have following the doc to invalidate the secondary copy and then simply connect. There is an excellent chapter in the manual about split-brain.
