You *must* at least prevent it from happening (perhaps by making the
raid array readonly if there is only one disk present). Otherwise, you
will get data corruption or data loss when the network is restored.

If you ignore cluster partition then it will never be a viable choice.
You don't have to solve the problem, but you do at least need to prevent
it from happening in some way.
For applications such as web or ftp servers, going readonly on a cluster
fault is perhaps quite acceptable.
