sudo
|
|
====
|
|
|
|
Using `sudo umount` you can unmount ANYTHING but need `sudo` access.
|
|
|
|
|
|
fusermount
|
|
==========
|
|
|
|
Using `fusermount -u` you can unmount all FUSE mounts.
|
|
|
|
|
|
pumount
|
|
=======
|
|
|
|
Using `pumount` you can unmount all mounts below `/media` which don't appear in `/etc/fstab`.
|
|
|

|
Shutdown/Reboot hangs
|
|
=====================
|
|
|
|
If there are mounted *cifs* shares, you might encounter a *"CIFS VFS: no response for cmd 50…"* on shutdown or reboot
|
|
which may take about half a minute before the machine actually shuts down (or reboots). This is caused by the network
|
|
being shut down before the shares were umounted.
|
|
|
|
The thing is, in Jaunty there already is a script to umount network shares before the network is shut down, but it has
|
|
the wrong start-type of `S` = start. If you look at the script itself, you'll find this:
|
|
|
|
{% highlight bash %}
|
|
case "$1" in
|
|
start)
|
|
# No-op
|
|
;;
|
|
restart|reload|force-reload)
|
|
echo "Error: argument '$1' not supported" >&2
|
|
exit 3
|
|
;;
|
|
stop|"")
|
|
do_stop
|
|
;;
|
|
*)
|
|
echo "Usage: umountnfs.sh [start|stop]" >&2
|
|
exit 3
|
|
;;
|
|
esac
|
|
{% endhighlight %}
|
|
|
|
So if called with the argument `start`, it will do nothing. It has to be called with `stop`.
|
|
|
|
To fix this (in Jaunty):
|
|
|
|
* go to `/etc/rc0.d/`
|
|
* find the link `S31umountnfs.sh` (type: S = start)
|
|
* do a `sudo mv S31umountnfs.sh K31umountnfs.sh` (type: K = kill/stop)
|
|
* now go to `/etc/rc6.d/` and do the same to the link there
|
