Fundamentally, it comes down to this: the two clusters will still have the same fsid, and you won't be isolated from configuration errors or leftover state (such as the monmap) in any way. There's a high chance that your "let's poke around and debug" cluster wrecks your healthy cluster. > By the way, is using 2 mon instance with different ports supported ? Monitors are identified by ip:port. You can have multiple bind to the same IP address, as long as they get separate ports. Naturally, this practically means giving up on high availability. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
