How to recover from split brain?


(Srividhya Umashanker) #1

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.

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?
