Hmm, non-unique UUIDs? That makes them fairly useless :-) Do you know, is that actually part of how the btrfs-builtin RAID-0 mode works? I'm familiar with md where you get one virtual device with the actual file system, and the underlying RAID components don't have a mountable file system and still separate UUIDs, which is a lot simpler to handle. Do you have a pointer to documentation how to set up such a system?
