    Hello guys,
    I have a problem with mdadm.
    I created three partition ( swap, / , /home) and I have configured swap in raid0 and /home in raid1.
    When I configure in raid1 / with mdadm, the system return this message:

    mdadm: super1.x cannot open /dev/sda2: Device or resource busy
    mdmon: ddf: Cannot use /dev/sda2: Device or resource busy
    mdmon: Cannot use /dev/sda2: It is busy
    mdadm: cannot open /dev/sda2: Device or resource busy

    cat /proc/mdstat
    Personalities : [raid0] [raid1]
    md1 : active (auto-read-only) raid1 sdb2[1]

    How I can fix?
