unable to unmount a file system

[changee]

Hi,
iam trying to unmount a local file system , but am getting the following error:

apps1 # umount /Application
umount: cannot unmount /Application: Device busy
umount: return error 1.
apps1 # pwd
/
apps1 # lsof | grep /Application/
apps1 # fuser -cu /Application
/Application:

apps1 # fuser -kcu /Application
/Application:

apps1 #


Can some some tell me why am not able to unmount the file system, eventhough no users or sockets are using it.?

Someone is using it. Is it NFS-exported?

> apps1 # lsof | grep /Application/

Why search for the "/" characters (especially
the second one)?

Hi all,
thanks for your inputs..
i couldnt figure out what was wrong with the 'umount', fortunately I had a downtime on that server and everything came fine after the reboot.even 'umount' started working .!!..Really surprised of what went worng here.
Its a local file system, not NFS exported to any other server.
thanks alot,
