So far, I successfully managed to create a core from my existing configuration by opening this URL in my browser:

I copied the files data-config.xml, schema.xml into a new directory "/etc/solr/glinstance" and tried to create another core but this always throws me error 400. I even tried by adding the schema- and config-parameters with full path, but this did not lead to any difference. Also I don't understand what the "dataDir"-parameter is for. I could not find any data-directories in /etc/solr/ but the creation of the first core worked anyway. Can someone help? Is there any better place for my new instance-directory and what files do I really need?
