So we have a solr 6.6.3 deployed in AWS EC2 instance (dockerized) and during our load testing, our script for some reason removed 1 replica. So I decided to add 1 replica in the shard with only 1 replica and it returned the error message in the title.
Whan can cause this? We have another collection in the cluster and it can easily add a replica but this particular collection proved to be problematic. -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
