Hi, It might be an issue with deactivation. Try update to 2.6 or wait 2.7. Right now just skip cluster deactivation. Once you formed a baseline topology and finished loading data, just enable WAL log for all caches. When log enabled successfully, you can safely stop nodes. On next time when all baseline nodes joined cluster, it will be activated automatically.
