Happy to see it around. The manual states..: > When primary hastd is unable to connect or connection fails, > it will try to re-establish connection every few seconds. > Once connection is established, primary hastd will synchronize > every extent that was modified during connection outage > to the secondary hastd. Question: For how long can a secondary be offline before a full synchronisation becomes necessary? In other words, on which resources and/or tunables does this depend upon? Great work pjd, I guess we're all big fans of all your GEOMs, and this is a welcome new one :) big Regards, Lorenzo
