I am using solr 4.5. After several tests I have noticed a lot of dead (non existing) replicas are shown in my SolrCloud graph as gone (black). Is there any way to force my solr to forget about this gone replicas?
I think that manually modifying /clusterstate.json node in zookeeper might help but did not try it yet.
The simplest way I found is in fact editing /clusterstate.json in zookeeper, and removing dead replicas info from it.
