Since I want to keep a local backup of the index, I guess it might be better to first call "UNLOAD" and then "CREATE" after having moved the current index data to a back dir and having moved the new index data into position. Now "UNLOAD" has the feature of continuing to serve existing requests. In my case I actually lock the slaves, so there shouldn't be any requests and if so, they do not matter anyways. I do not want to shutdown the solr server in order to not accidentally tick-off the monitoring. But I also want to make sure I do not corrupt the index (then again I am only reading anyways). But I am worried if for some reason there is still some request open and I do not poll via STATUS action to make sure the core is UNLOADed, that I might corrupt the index. regards, Lukas Kahwe Smith m...@pooteeweet.org
