umount Omni

[Macho_2]

I try to unmount the following omniback directory
/var/opt/omni
But received the following error :-
aros34 [/]umount /var/opt/omni
umount: cannot unmount /var/opt/omni : Device busy.

Before unmount the filesystem, I already stop the Omniback daemon by following command :-
cd /opt/omni/sbin
omnisv.sh stop --- . successfully stop.

Please advice how to unmount the directory.

Eventhough you have stopped the daemons there may still be some agents running. First do a 'ps -ef | grep "omni"' to see if any processes are found. If so, kill them. You may also have a shell that is using /var/opt/omni as its current working directory. You can try fuser to find process that have the filesystem in use but ,by far, the best tool is lsof. It will spot processes having the filesystem in use in a heartbeat.

Thank you very much. I managed to unmount the filesystem.
