Re: [Neo4j] Lucene index recovery
You could configure the lucene data source to auto rotate logs more frequently. If logs are large recovery takes longer time. -Johan On Mon, Oct 17, 2011 at 11:37 PM, Nuo Yan yan@gmail.com wrote: What if in production due to whatever reason the neo4j server died and in the case people have to start up a new server with the current snapshot of data (which would be data from a non-clean shut down). In such case, I don't think it's acceptable to table lots of time (hours for large indices) to bring the server back. Is there a best practice here?

Re: [Neo4j] Lucene index recovery
It might be that you're not shutting down the server correctly (bin/neo4j stop) or that it's shut down at the same time as there are transactions running. Could you supply your data/graph.db/messages.log to me or look in it to see if there are any lines containing: Close invoked with An example: Close invoked with 3 running transaction(s) 2011/9/1 Peter Neubauer peter.neuba...@neotechnology.com Dima, are you shutting down your database correctly?
