What version are you upgrading from? Starting in version 8.6, the security manager Solr is using blocks access to locations outside of the Solr home. The allowed paths are set in solr.xml and the solr.xml that Solr ships with references the "solr.allowPaths" system property for that setting. https://solr.apache.org/guide/solr/latest/configuration-guide/configuring-solr-xml.html Thanks, Shawn Rydym yn croesawu derbyn gohebiaeth yng Nghymraeg.
