how to: automatically umount cifs partitions

[imota]

I realize this is an older topic but I have tried every single suggestion on here to no avail, on Ubuntu Lucid 10.04 x64 desktop.

I found a solution to my problem, after 3 days of debugging and searching the net so I thought I'd share it here.

I have the combination of a M$ Server08 with authenticated shares that I'd like to mount on startup (all entries on my fstab), which worked great. The problem was at shutdown...

My /etc/fstab looks like:

#WINDOWS SERVER SHARES
//192.0.0.212/user	/media/user cifs credentials=/etc/samba/.smbcredentials,file_mode=0777,dir_mode=0777 0 0
//192.0.0.212/ITEngShare	/media/ITEngShare cifs credentials=/etc/samba/.smbcredentials,file_mode=0777,dir_mode=0777 0 0
//192.0.0.212/EngineerShare	/media/EngineerShare cifs credentials=/etc/samba/.smbcredentials,file_mode=0777,dir_mode=0777 0 0
//192.0.0.212/ITEngShare/ScannedDocs	/media/ScannedDocs cifs credentials=/etc/samba/.smbcredentials,file_mode=0777,dir_mode=0777 0 0

I was getting the CIFS VFS cmd 50 errors on shutdown or reboot. I tried:

• Using Max Durden's script at the beginning of the post
• Changing the shutdown order of my scripts (rc0.d and rc6.d)
• Adding the umount -a command to my /etc/gdm/PostSession/Default
• Changing my umountfs.sh to a number smaller than my wpa-ifupdown
• Using various different scripts found in various other sources for this problem

I also was using network-manager for gnome, which a lot of people mentioned as being one of the culprits for the system hang during shutdown and reboot.

Finally I installed wicd and removed network manager; That solved the shutdown issue (although I am not convinced that my drives are being properly unmounted due to the sheer speed of shutdown... Someone might be able to shed light on this one?), but it created a new problem: Nothing was getting mounted at startup, due to the fact that wicd will not connect to the network until well into the GDM session has started.

So the solution was simple: Add the network information manually to /etc/network/interfaces. That causes ifup to pick it up during bootup before fstab is read, hence giving me consistent results.

Just add your interface to the file /etc/network/interfaces. In my case I added to the bottom of the file (static IP):

auto eth0
iface eth0 inet static
address 192.0.0.208
netmask 255.255.255.0
gateway 192.0.0.253
dns-nameservers 192.0.0.212

I hope this helps others that are frustrated by this seemingly overlooked issue with Ubuntu.

Edit:

I forgot to add my rc0.d and rc6.d as they stand today:

Unfortunately here doesn't work

i've made all the process you mentioned but it happens the same. sometimes i can logoff
and sometimes not

i'm using pam_mount.conf.xml to mount shares because i'm using the username and password from my server.
My machine as for about 60 users and i don't want to use credentials

i don't know what can i do

can you help me?

using: Ubuntu 10.04 LTS

great!
I had the following msg with ubuntu 10.04 Lucid Lynx on shutdown:

(the ubuntu ..... screen appeared and hanged, message appeared when pressing [Esc])

Deconfiguring network interfaces  

Your script works!!

thanks!

No luck here after upgrading to 11.04. Any recent cure??

[peterhorlings]

I'm using 11.04 and still had this OLD problem with a FreeNAS SMB/CIFS share. Both scripts mentioned at the beginning of the thread worked for me. Currently I'm using the second script which has been added on page 2 of this thread.
A big thank you to max.durden and sander marechal.

Great solution! Obviously still or again necessary in Kubuntu 11.10. Works fine for me. Since I needed quite some time to find this post I only reply to add some of the keywords I was initially using.

Kubuntu shutdown and restart problem samba cifs share over WLAN

I am not a geek so I may be allowed to wonder why the order of shutting down things has not been generally changed since the beginning of this thread.

Many thanks, as expressed before - this script worked well for me too. Thank you max.durden and sander marechal.

Have to say that I echo Bodo Bootlin's comments; this seems to have been an issue for some time, and hasn't been fixed in the standard distro.
