Hi, I am still quite new to Solr. I have the following setup: A SolrCloud setup with 38 nodes, maxShardsPerNode=2, implicit routing with routing field, and replication factor=2.
Now, I want to add replica. This works fine by first increasing the maxShardsPerNode to a higher number and then add replicas. So far, so good. I can confirm changes of the maxShardsPerNode parameter and added replicas in the Admin UI. However, the Solr Admin UI still is showing me a replication factor of 2. I am a little confused about what the replicationfactor parameter actually does in my case: 1) What does that mean? Does Solr make use of all replicas I have or only of two? 2) Do I need to increase the replication factor value as well to really have more replicas available and usable? If this is true, do I need to restart/reload the collection newly upload configs to Zookeeper or anything alike? 3) Or is replicationfactor just a parameter that is needed for the first start of SolrCloud and can be ignored afterwards? Thank you very much for your help, All the best, Johannes
