Hi Team,  
I am trying to open an old filebeat index but as soon as i opened it my elasticsearch cluster become "red" due to unassigned shards. This results elasticsearch and blocking logstash as well.

On 1-Sep-2016 for which i am trying to open the index i was using default shards and replicas which i now changed to shard=2 and replica=1. Am i getting error because of this? what else can cause unassigned shards? Please suggest.

# ============================================ I checked elasticsearch master node logs and couldn't find any error: [2016-10-14 10:52:59,214][INFO][cluster.metadata] [es-master-node] opening indices [[filebeat-2016.09.01]] [2016-10-14 10:53:15,016][INFO][cluster.metadata] [es-master-node] closing indices [[filebeat-2016.09.01]] [
