Hi there.

Just a quick question: How do I rename an existing btrfs filesystem
without destroying all the subvolumes on it?

>>From mkfs.btrfs it says -L sets the initial filesystem label.

With ext2, 3 and 4 the filesystem label can be changed with tune2fs.
Does similar functionality exist in btrfs?

Thanks for any response.
