<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>
