Shawn, I first deleted the collection from the admin interface. It didn“t work.
When I deleted direct on command line it worked: /opt/solr-6.6.2/bin/solr delete -c <my collection> Thanks for the advice on using schemaless on production. I understand the potential problems, so I will first create schema automagically on schemaless mode, download it adjust and upload to zk as described on the documentation.
