You can't change the uuid of an existing btrfs partition. Well, you
can, but you have to rewrite all the metadata blocks.
The performance problem you're hitting is probably from metadata seeks
all over the place. Jeff Liu has a new snapshot diffing tool in
development that may make for less IO from rsync.
Care to share you rsync script?
