    Can't Mount BTRFS after using label command

    After putting scads of data on an BTRFS, I decided to label it. I used:

    btrfs filesystem label /dev/sdb1 music
    When I try to mount it, it says

    mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
    missing codepage or helper program, or other error

    When I tried to fix it, I used
     btrfsck --repair /dev/sdb1
    The response was
    enabling repair mode
    Checking filesystem on /dev/sdb1
    UUID: 6cb33fb7-cef5-4d19-b327-a4f5054c3145
    checking extents
    checking fs roots
    checking root refs

    Btrfs v0.20-rc1

    I still can't mount. I would like some help.

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
    Use the LABEL=music directive in your mount command, or /etc/fstab.
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!
