Didn't wipefs tell you? I don't have any btrfs but for me wipefs prints at which offset it found which label. Like this, for a Linux swap partition: # wipefs /dev/sdb5 DEVICE OFFSET TYPE UUID LABEL sdb5 0xff6 swap 8af9fb67-38ca-4c91-bbbd-d53c5ac1f30a And if I hexdump a bit of /dev/sdb5 I get: 000ff0 00 00 00 00 00 00 53 57 41 50 53 50 41 43 45 32 >......SWAPSPACE2< 001000 01 00 00 00 8a f9 fb 67 38 ca 4c 91 bb bd d5 3c >.....ùûg8ÊL.»½Õ<< 001010 5a c1 f3 0a 00 00 15 00 80 00 ff ff ff ff 03 00 >ZÁó.......ÿÿÿÿ..< 001020 00 00 01 00 00 00 00 00 00 00 3d b5 04 00 00 00 >..........=µ....<
