The logging tab in the admin UI will by default show all messages at WARN and higher severity. If you're not seeing WARN messages there, then a configuration has been changed to get rid of them. Regarding general disk space requirements: There should always be enough disk space so that all the indexes can double in size temporarily. To be absolutely certain you won't run out, it should be enough space so they can triple in size temporarily -- there is a certain indexing scenario where this can happen in the wild. Replication can also create an entirely separate copy of the index temporarily, so the same disk space recommendations apply for that too. Thanks, Shawn
