Thanks Ben,
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?

We has deployed manila service in production. But we have

we're deploying it in this network.
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.
I'm wondering how can we change the network of manila without
affecting the existing service?
Can we leave the existing virtual machines which continue to
serve while restarting manila with the new configuration? Does it work
for the existing service?
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:
* 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.
* If you're using a driver without share servers, simply reconfigure
your storage controller, and restart the Manila service.
