Newbie - Unmounting an NFS mount

[joel7]

Were using a Sun Station for an Avaya app. I needed to mount a Windows 2003 drive for backing up. That worked well, I was able to mount the drive. Now I need to chnage the IP of the mount location, but I cant do it. Ive tried doing umount and the name of the mount and Ive also tried stopping the NFS client. No matter what I try, I get "nfs umount: /mnt: is busy". I havent been able to unmount this. Any help would be greatly appreciated.

Are you in /mnt when you try to unmount /mnt?
Is there any other terminal in /mnt?
Is /mnt shared?

If you are using Solaris 9, you can force the unmount. I think it is a umount option... Look at man umount.

Actually, using man umount, I was able to find an option for forcing an unmount using the -F option. Thank you for your help.

if you have lsof command on your host you can find out which file is open on /mnt, this may give you a hint why /mnt is busy... (fuser -c ... is a similar OS Command)
