I am new to redis clusters. I started to make a 3 node redis cluster. As part of load testing I found that if Master goes down it is promoting slave as a master but configure file is not getting changed in both master and slaves. So When I stop start the downed master instance it is again becoming the master with no connected slaves. This is production environment and I can't afford a downtime.
Help me how to solve the issue..
Please provide your setup: How many master nodes initially? How many slave nodes?
Please provide the log of all instances.
