The primary shard for the .kibana index of Kibana is there in Node B along with all other primary shards. Node C has the .kibana index replica shard. Now once I take Node B out, all the replica shards in Node C will become primary along with the .kibana one too.
Now once I add Node B back, will it hold only replica shards now ? If yes then Kibana will read from the .kibana index replica shard now. Will it cause any difference ?
