That definitely looks like the problem that Micheal describes. And it indicates that restarting Solr instances after restore is a workaround. The issue also says something that might indicate that collection reload after restore would also fix it, but I can't be sure about that part. If it works, that would be far less disruptive than a Solr restart. I've tried to reproduce the issue with the cloud example on 7.3.0, but I can't get the collection restore to work right and give me two replicas. Thanks, Shawn
