The Lucene class that gets the index size only knows about the live index. The transaction log and any other copies of the index are invisible to it. The additional index copies are probably either from running the backup option on the replication handler, or from replications that didn't work right for some reason. If you were running a newer version of Solr, you would be able to see the index directory in use by the core right on the core overview. See the "Instance" section in the upper right corner of this screenshot from Solr 4.7.2: https://www.dropbox.com/s/n3c10vj81aqpfjy/core_overview.png Based on the index size, I think we can figure out which index.nnnnnnnn directory you should NOT delete - the one that's 75GB. You can ask the admin UI to tell you exactly which directory is in use, though. Go to Plugins/Stats, CORE, then open "reader" ... you should end up at a page like the following. The "readerDir" value will have the actual path that you need to keep. https://www.dropbox.com/s/mzml8pgg1d30h0t/stats-core-searcher.png Thanks, Shawn
