How to fight "The requested resource is busy" message

I'm pretty sure a lot of people were looking for answers and came across the referenced thread. I, myself, bumped into it several times.
Since that thread is closed, I thought it would be wise to post a possible solution for that issue:


<hostname>:{root}# umount /dev/backup_S_01
umount: 0506-349 Cannot unmount /dev/backup_S_01: The requested resource is busy.
<hostname>:{root}#
<hostname>:{root}# fuser -kcuxV /dev/backup_S_01
/dev/backup_S_01:
vfs 66534c(imdba)

<hostname>:{root}#
<hostname>:{root}# umount /dev/backup_S_01
<hostname>:{root}#

Use of -k switch kills any process which uses the resource without a warning. Use -i switch if you expect to get a prompt before killing it.

Have you already tried using umount -f /filesystem?

I usually fix few NFS resource busy with it!
