I encountered Split Brain Scenario. What steps to follow to recover from it, without losing data ? Just restarting the nodes alone does not solve the problem. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hi, Had you configured dedicated master nodes and a minimum number of eligible master nodes[1]? If not, I would recommend to at least set minimum\_master\_nodes in order to prevent this issue from happening again in the future. In order to recover from this issue, can you try to restart your whole cluster?
