ElasticSearch Clustering- Creating Index creates unassigned shards

Question

Hello Guys while creating index in elasticsearch cluster, All my replication shards are in UNASSIGNED state due to which i am not able to reindex and the cluster goes to red status. Can you guys help this is I have spend nights to solve this.

Update -- Number of Nodes are 2.

"cluster_name": "cluster-name",
   "status": "red",
   "timed_out": false,
   "number_of_nodes": 2,
   "number_of_data_nodes": 2,
   "active_primary_shards": 2,
   "active_shards": 2,
   "relocating_shards": 0,
   "initializing_shards": 3,
   "unassigned_shards": 5,
   "delayed_unassigned_shards": 0,
   "number_of_pending_tasks": 0,
   "number_of_in_flight_fetch": 0,
   "task_max_waiting_in_queue_millis": 0,
   "active_shards_percent_as_number": 20

I am creating just 8 shards and 1 replication shards. While doing this all my replication shards goes to unassigned state and all my shards of non-master node goes to initializing state.

Also whenever i delete this index my cluster comes to green state.

If you don't have sufficient disk storage to store primary shards, your cluster state will turn into red. If your configured data node disk goes beyond 90% your cluster turns into yellow. So please check data node's configured disk storage.
