how to: automatically umount cifs partitions

[diana.artemis]

Oh no! I upgraded yesterday to karmic and this problem again! Will the Ubuntu team never fix this?!

Has anybody logged a bug already?

This is a long-standing Debian issue, with internal arguments about whose 'fault' it is paralysing any action to fix it. See, for example,

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=431966

or

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=481252

Look at the dates; and if you have the time and patience to investigate a bit more you'll find it's been going on for years longer. (Free software at its worst.)

I found a fix for the CIFS VFS error issue during shutdown & reboot. It works on Karmic while using wireless. I posted it here:

It really works great now!

Thanks Dude!

Hey All,

I have had this problem too. I am working presently on Karmic and access network from wireless and wired connections at different times.

I tried three different solutions for this problem:
1. The one given here: http://ubuntuforums.org/showthread.php?t=1347340
2. The one given by dmizer here: http://ubuntuforums.org/showthread.php?t=288534
3. And the one given here: http://ubuntuforums.org/showthread.php?t=293513

However none of the solutions fixed my problem. I read in one of the posts that the real problem was to run the /etc/init.d/umountnfs.sh before the system is killed.

This gave me the simple idea, since I always have a terminal open, I wrote this bash function:

function bringdown()
{
sudo /etc/init.d/umountnfs.sh && sudo shutdown -h now
}

This simply solves my problem.

However I was thinking of a more generic solution. I have never tried scripting. I was wondering if there can be a more elegant and generic solution to this. I have an idea, someone please let me know if this is feasible.

We can create a script which runs this function `bringdown' as given above (preferable without the need for a sudo password prompt [perhaps using a credentials file or using editing visudo]) and put this in the $PATH of each user, so that one can simply call the run dialog and bring the system down.

Please let me know if writing such a script is possible and easy. I am willing to learn and do homework if any is needed.

Thanks for reading the long post. Hoping for some replies.

As a temp solution I've added a link to sudo /etc/init.d/umountnfs.sh next to the shutdown button so I can click on that before hitting shutdown. Very much a cludge but it seems to work.

If someone can come up with a better solution for 9.10 then please, please let me/us know.

Im a new to linux, and ubutnu are new for me. Im a former windows user.
So culd you give me a step by step howto make a link next to the shutdown button??

After spending a day working out how create fixed icons on the desktop that mount shares as and when needed i discovered this same problem when shutting down, it's just taken me another day to find a solution.

I can't believe the complexity of the solutions given in this thread, and not one would work on 'Kinky' (9.10). This has obviously vexed a lot of people so I feel bound to share this with you all.

add a line in /etc/gdm/PostSession/Defaults

umount -a -t cifs

Simples!

you dont even need sudo.

I hope this helps some people.

And in case you were wondering about my initial project here it is:

# reasons for this script:
# 1. mounting at boot increases start-up time
# 2. network folders not always available at boot
# 3. unable to play video & audio from smb share
# 4. desktop launchers for fstab mounted volumes tend to appear in random positions
# 5. allows for custom geometry of browser window
# 6. browsing to smb shares creates extra items in nautilus tree
# 7. nautilus folder icon can be customised

# requirements
# 1. create mount exception in sudoers with visudo
# 2. mount-point folders must exist (in /media)
# 3. share name must be same as folder name
# 4. credentials file should exist (smb)
# 5. use config editor to turn off 'volumes visible' (optional)

# automatic umount on logout (prevents hang at shutdown)
# 1. open /etc/gdm/PostSession/Default as root
# 2. add the line > umount -a -t cifs

# usage
# mnt <share name> [--geometry=<width>x<height>+<left>+<top>]

# example
# create custom application launcher
# enter as command ./mnt tunes --geometry=1018x593+0+56 (assuming in ~)

# result
# mounts share 'tunes' in /media/tunes
# opens large browser window in middle of screen (1024x768) in /media/tunes

# check for no args
if [ "$1" = "" ]
then
    echo "No value given"
    exit

# is volume in the list of mounted volumes
a=`sudo mount | grep $1`

if [ "$a" == "" ]
then    # no?, then mount
    # seperate case for windows needed
    if [ $1 == "windows" ]
    then
        sudo mount -t ntfs-3g /dev/sda1 /media/$1 \
        -o rw,user,locale=en_GB.UTF-8

            sudo mount -t cifs //192.168.0.253/$1 /media/$1 \
        -o user,rw,credentials=smb 
    fi

    # check again (see if mounted)
    a=`sudo mount | grep $1`
    # if entry for $1
    if [ "$a" != "" ]
    then
        echo $1" successfully mounted."
        # open in file manager
        nautilus /media/$1 $2

Hmm...

it also appears to need this:

ln -s /etc/init.d/umountnfs.sh /etc/rc0.d/K15umountnfs.sh
ln -s /etc/init.d/umountnfs.sh /etc/rc6.d/K15umountnfs.sh

and a '-f' for the umount helps speed things up

[microscott]

I give up!

A couple of reboots and it's as it was.

easier to just do umount -a in terminal.

I got an amateur solution... two launchers It's not the best solution, but it works for me at 100%

Just perfect! Thanks!

Hi everybody,
I'm posting a modification of a simple script originally coded by 'jferrando'
http://www.ubuntuforums.org/showthre...highlight=cifs
devoted to automatically umount cifs partitions in the shutdown and reboot sequence of Ubuntu (Dapper+). The main problem with the original script was that mount locations of cifs partitions had to be explicitly hardcoded in the script: I have written a simple routine which detects all mounted cifs-partition and umount them before proceeding with the other phases of the shutdown/reboot sequences.

-----------------------------------------------------
Instructions are very simple:
uncompress archive and set 'chmod +x' on the mountcifs file
sudo cp mountcifs /etc/init.d/

cd /etc/rc0.d
sudo ln -s /etc/init.d/mountcifs K02mountcifs

cd /etc/rc6.d
sudo ln -s /etc/init.d/mountcifs K02mountcifs

...that's all!
------------------------------------------------------
I've experienced problem in the shutdown of my laptop just after sharing cifs filesystems with other PCs in a VPN network... this script fixed the problem.... hope it will be useful for someone out there!

Happy Coding
Max
