Force unmount a partition.

[chakri78]

I have two hosts configured with drbd. I want to make sure no one is using the partition before i do a switchover. Is there a command to forcefully unmount a partition? i tried fuser -ku but not killing all the processes using the partition.

Thanks,

sudo umount -l /dev/sdxy

that is a lower case L

I think it stands for lazy unmount...
