mkraid /dev/md7 doesn't works

[santoshdj123]

hi
i unmount all raid partitions. but i can not unmount /dev/md7 raid partition. i tried to kill but still doesn't works.
what is the procedure to stop this /dev/md7.
because after stopping that i need to mkraid all raids.

sorry for mistake.
it is not mkraid. it is raidstop.
so please raidstop instead of mkraid.

Do you get an errormessage?
Which?
Perhaps /dev/md7 is mounted to a vital point which is 'in use'.

How did you try to kill a mount???
