Currently you need to delete and recreate the volumes, because the
servers don't know how to handle changes in the VSGDB, so they will be
confused about who is a member and who isn't. There is also no way of
informing clients that the cached volume replication information is

I've been thinking about adding this functionality and the clients are
almost ready for it, they (hopefully) just need some sort of callback to
trigger revalidation of the cached replicated volume information. The
server side of the equation still needs a lot of work.
