Hi
I have a collection which has 4 shards with 2 replicas each. These 8
replicas are running on 8 nodes.
For scaling, when I add a new node and add a replica, it fails with the
following error:

I've tried recreating the collection from scratch (with new zookeeper path)
and it fails again. What could be going wrong here?
This is my create collection command:
curl
'http://localhost:8080/solr/admin/collections?action=CREATE&name=collection_y&shards=shard1,shard2,shard3,shard4&replicationFactor=2&collection.configName=collection_y&router.name=implicit&router.field=shardfield'
