We are using Bitnami solr 6.2.1 with sitecore 8.1 update 3.
Every thing is just working fine in our development and qa environment. The issue is, whenever these environment gets rebooted or restarted for any reason, all cores from the solr server are detached. However all related files for these cores are still there in the file system.
Thus, every time we restarted server, we need to add all related cores back to the solr server.
Is there any way, not to loose these cores from solr while server restart.
