How does one unmount when umount doesn't work?
Somehow, I got an NFS / AutoFS mount that just won't unmount.
I noticed /var/autofs/net was mounted twice, so I stopped AutoFS &
tried killing the remaining automount process. "kill 14986" didn't
work; I needed "kill -9 14986". The following mounts remain:
wum:~# mount
[...]
automount(pid14986) on /var/autofs/net type autofs
(rw,fd=5,pgrp=14986,minproto=2,maxproto=4)
tor:/home on /var/autofs/net/tor/home type nfs
(rw,nosuid,nodev,hard,intr,addr=192.168.103.158)
& I can't unmount them:
wum:~# umount /var/autofs/net/tor/home
umount: /var/autofs/net/tor/home: device is busy
umount: /var/autofs/net/tor/home: device is busy
wum:~# umount -f /var/autofs/net/tor/home
umount2: Device or resource busy
umount: /var/autofs/net/tor/home: Illegal seek
umount2: Device or resource busy
umount: /var/autofs/net/tor/home: device is busy
wum:~# umount /var/autofs/net
umount: /var/autofs/net: device is busy
umount: /var/autofs/net: device is busy
wum:~# umount -f /var/autofs/net
umount2: Device or resource busy
umount: automount(pid14986): not found
umount: /var/autofs/net: Illegal seek
umount2: Device or resource busy
umount: /var/autofs/net: device is busy
I triple checked that no process is using these mounts. How do I
unmount them?
Thanks!
Jack

See the manpage description of the "-l" flag to umount.

What versions are you using?
Kernel version?
Patched?
Try the autofs list at

So perhaps you are using Fedora core 3?
With kernel version?
Can you duplicate this easily?
