      <div>We will reconfigure manila to use the correct network. I'm
        still wondering will it have an effect on our existing services?
        Some users have create shares in our environment(240.0.0.0/8 is
        an example and we're using the available one). What if we
        upgrade manila to use something like 10.240.0.0/24, can they
        continue to use the existing shares in 240.0.0.0/8?</div>

    It's possible, but it will depend on your network configuration. As
    I said below, class E addresses are invalid, so the fact that it
    works at all is a bit surprising. I'm sure if it's working now,
    there is a way it can continue to work, but there's too many unknown
    variables for me to tell you how.<br>
    <br>
    My recommendation would be to stop using the 240.0.0.0/8 addresses
    altogether and move everything to valid IP addresses. That move
    might end up being disruptive, so the sooner you do it the less
    problems it will cause.<br>

            240.0.0.0/8 is a class E address, which is invalid, so
            blocking by your OS is correct behavior. You should use one
            of the RFC1918 IP address ranges for actual traffic.<br>

            Manila doesn't offer a way to change the network
            accessibility of existing shares. In the future we'll be
            able to do share network changes and migrations, but today
            you have the following options:<br>
            * If you're using a driver with share servers, create a new
            share network with the correct network subnet and create new
            shares using that network.<br>
            * If you're using a driver without share servers, simply
            reconfigure your storage controller, and restart the Manila
            service.<br>
