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.

There's a patch for btrfsprogs which introduce a new command: btrfslabel
https://patchwork.kernel.org/patch/70701/
You might need to make some changes to merge it with current version,
but the userland-only patch works great for changing unmounted btrfs
filesystem. It works even without the kernel-side patch.
