So entire cluster was down. I m trying to bring node by node . I restarted the first node . The solr comes up but add replicas command fails. And then I tried to check clusterstatus api, it showed shard in active state, no core as active i.e. all down and one live node which was the one that I restarted. Also this all connects to one zookeeper ensemble of 3 nodes
