Cannot unmount from external hard drive


After completing copy of data to some hard drives, I had problems trying to unmount the drive...(I'm using Suse Linux 9 Enterprise).

When using umount -f /mnt/md0 I receive a message that the drive is busy.

I have checked to make sure I am no longer in this drive and that all screens have been detached that were previously using this drive.

When I do a ps -ef | grep md0 the response I receive is "[md0_Raid5]"

After unmounting the drive I was going to run the command:
mdadm --misc -S /dev/md0

Does anyone know if I am going about this correctly? Should I be executing the second command before unmounting the drive?

Thanks in advance.

The array must be mounted in order for mdadm to see it.

Are you trying to use mdadm to deactivate the array and get access to individual drives? What is it that you want to do?
