doesn't gnbd recognize size changes? If you export logical volumes (lvm2) from 
the storage server(s) with gnbd you are able to resize the logical volumes!? 
Do the gnbd clients notice the changes?

Without clvm you could use gnbd. Does the gnbd client notice when the gnbd 
server adds a new gnbd export?
