In some occasions you ould need to kill all the process running by a partition in order to umount a partition for example, the following command can be used to kill all the processes running by /dev/sdb1
~#fuser -c -k /dev/sdb1
The parameter C is to kill all the processes
The parameter K is to kill all the processes
Then you can umount the partition without having an error saying "partition is busy running processses"
