I encountered this problem often when i restarted a solr instance before replication was finished more than once. I would then have multiple timestamped directories and the index directory. However, the index.properties points to the active index directory.
The moment when the replication succeeded the temp dir is renamed "index" and the index.properties is gone. On the situation when the index is missing, not sure about that. Maybe this happens when the replica is too old and an old-school replication is done. ----- Thanks, Michael -- View this message in context: http://lucene.472066.n3.nabble.com/Multiple-data-index-YYYYMMDD-dirs-bug-tp4102163p4102168.html Sent from the Solr - User mailing list archive at Nabble.com.
