Smile how to remove raid partion?

in RHEL5. i already create raid partition by using mdadm. dev/md0 there are raid level 0 and have two raid device dev/sda6 dev/sda7. Now i want to remove one of them "dev/sda7".i using this command: # mdadm --verbose /dev/md0 -f /dev/sda7 -r /dev/sda7 but error said: cannot remove active disk sda7 from md0, hot remove failed for /dev/sda7: device or resource busy. i already unmount, so why still said device or resource busy?

Thank you.

Check /etc/mtab to verify unmounted resource.
