Somehow one of my server got into split brain situation, how can we reset & sync back one of servers's data with another master.
i won't mind lossing one's set of new data but i want now that detached server to in sync with others.
suppose i've only two servers. because after split brain now its not more be able to join group replication because it has many more new transaction and another one also have many new.
there is similar question for normal master slave mysql config How to re-sync the Mysql DB if Master and slave have different database incase of Mysql replication?
but here i am talking about group replication in mysql.
