NFS guru's, I need your help!!!!!

Is there any way to unmount a NFS filesystem while it's busy?

ie. someone has a file opened in the filesystem, but I wanna forcefully unmount it...

When I try to do it now, it reports the filesystem is busy and cannot be unmounted...

Any help would be great!

What's an NFS filesystem?

We use AFS at work, but no NFS....

NFS = Network File System

Basically you use NFS to access a drive on another machine through the network... You just mount it using NFS, and it will be like a local drive...

I'm almost positive there's a switch to force the unmount. Check your help file, meanwhile I'll look around to see if I can find it.

Use -f .

I have tried that already...

umount -f can unmount a filesystem if the other side went away (eg. A mount to B, if B crashed, A can umount using -f option)...

But -f does not do the trick if a file system is busy...

In fact, in the man pages of umount, it said a file system cannot be unmounted if it's busy... I was just wondering if there are tricks you can do...

Down the network interface for 30 sec, force kill the process and bring the interface back up. There is always more than one way to skin a cat. You could also temporarily block access to the port NFS uses, etc..
