    I just tested my installation of Sarge on a Intel Server with 6 SCA HDs
    slot. I have partition swap, /boot, / at /dev/md0, /dev/md1 (ext2), /dev/md2
    (ext3) respectively. md0 are with sda1 and sdb1, md1 with sda2 and sdb2, md2
    with sda3 and sdb3. When I tested what would be happened when I unplug the
    sdb HD online, with wish to its normal operation, and cat
    /boot/grub/menu.lst. But the result is HD sda light flashing heavily with
    syslog fill with:

    Jul 19 16:58:37 debian kernel: raid1: sda2: rescheduling sector 475148
    Jul 19 16:58:37 debian kernel: raid1: sda2: redirecting sector 475148 to
    another mirror
    Jul 19 16:58:37 debian kernel: raid1: sda2: rescheduling sector 475148
    Jul 19 16:58:37 debian kernel: raid1: sda2: redirecting sector 475148 to
    another mirror
    ...
    ..
    It make me poweroff the machine to save the machine.
    What is happening? I would expect it should be normal failover...
