How do I get Solr back up when indexes are locked and true doesn't work?

Question

I have a Solr slave that is running in Tomcat. I added a core, so I changed solr.xml. To reload it I decided to simply restart Tomcat using the Windows Services managament conso

Answer 1

Delete file write.log in folder /data/index/ for your core then restart tomcat. It worked for me.
