: I know there was some effort to fix this but I must report : that solr 4.2.1 has still problems with index version and : index generation numbering in master/slave mode with replication. ... : RESULT: slave has different (higher) version number and is with generation 1 ahead :-(
Can you please provide more details... * are you using autocommit? with what settings? * are you using openSearcher=false in any of your commits? * where exactly are you looking that you see the master/slave out of sync? * are you observing any actual problems, or just seeing that the gen/version are reported as different? As Joel mentioned, there is an open Jira related purely to the *display* of information about gen/version between master & slave, because in many cases the "searcher" in use on the master may refer to an older commit point, but it doesn't mean there is any actual problem in replication -- the slave is still fetching & seraching the latest commit from the master as intended.... https://issues.apache.org/jira/browse/SOLR-4661 -Hoss
