Re: Stupid question re multiple networks

    AFAIK multiple network scenario only works if you are not using
    Gluster via FUSE mounts or gfapi from remote hosts. It will work for
    NFS access or when you set up something like Samba with CTDB. Just
    not with native Gluster as the server always tells the clients which
    addresses to connect to: ie your storage hosts will always supply
    the connection details of the hosts that are configured in gluster
    to your storage clients.

    
    I wonder if this could be gaffer-taped with some bridging/vlan/arp
    spoofing trickery but I'm not sure I'd trust such a hack.

    
    It would be *really* nice if there was a way to set up gluster so
    you could specify different IPs for backend and frontend operations.

        If I have a set of Gluster storage servers
          which have both a gigabit network connection and a 10Gig
          network connection
        (or an Infiniband network connection) how
          do I make sure the Gluster traffic goes over the 10Gig
          interfaces?
         
        Do I simply have to form a cluster with the
          hostnames associated with the 10Gig interfaces,
        Or is there perhaps a more sophisticated
          way to do this?
