raidstop my raid-array using, which i need to do before running
raidreconf.

/dev/md0: Device or resource busy.
%>
any suggestions... i have already tried unmounting the device.

try doing fuser -m on /dev/md0 to see which processes are using it...
# fuser -m /dev/md0
/dev/md0: 8685c
then us ps to figure out what's up

This is a bug in raidstop. If you strace you will notice that it
opens it twice and before trying to ioctl(STOP...) it.
Upgrade raidtools or use mdadm.
And a quick and dirty:
mv /dev/md0 /dev/mdx
mv /dev/md1 /dev/md0
mv /dev/mdx /dev/md0
raidstop /dev/md1
mv /dev/md0 /dev/mdx
mv /dev/md1 /dev/md0
mv /dev/mdx /dev/md0
should work.
