I'm not sure dhcdbd is affected because stopping it doesn't seem to bring down DHCP connections (at least not immediately).

[Bug 211631] Re: CIFS/SMBFS shares not unmounted before network is shut down
I tested the commands, Thierry, and there was no difference. I didn't really hold out a lot of hope, though, because I don't run the WPA supplicant. Everything works perfectly when I umount the CIFS filesystems before shutting down. I also found that Suspend and Hibernate modes work better too (as an aside). Strange, umountnfs.sh (I double checked it for cifs) runs before networking so of course one would have to think everything would be okay. Does the logging off of the Gnome session, ending the Network Manager in the notification area, have something to do with it? I wonder what would happen if the networking was all static startup/shudown entries and network manager was never run (or even uninstalled). -- CIFS/SMBFS shares not unmounted before network is shut down https://bugs.launchpad.net/bugs/211631 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 211631] Re: CIFS/SMBFS shares not unmounted before network is shut down
Hm, so that might be related to user-level network configurations from NetworkManager being brought down at session logout (typically the NM wireless connection falls in that category). It seems obvious this might not play well with network services (client or server) that expect network to be up very early (and very late). And that would not be as easy to fix as some think it is... as the "fix" would surely affect a feature that most people like. -- CIFS/SMBFS shares not unmounted before network is shut down https://bugs.launchpad.net/bugs/211631 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

I just tried wiring up my lappy, which is up to date with the distribution sources, and I have the same issue using Network Manager as I had with the wireless. An interesting test would be to code the activation of the wireless network connection into the local startup/shutdown process and remove Network Manager to see what happens. That wouldn't be a preferred solution, though, because the advantage to wireless is the ability to switch hot spots on the fly with NM.

I removed Network Manager with the Synaptic Package Manager (the network-manager and network-manager-gnome packages) and added my wireless startup information to /etc/rc.local like this: ifconfig eth1 down dhclient -r eth1 ifconfig eth1 up iwconfig eth1 essid "MY ESSID" iwconfig eth1 mode Managed dhclient eth1 sleep 5 mount -a -t cifs Everything now works perfectly as far as I have been able to tell. No delay in shutting down and the Suspend function seems to be working properly as well -- sorry I haven't tested Hibernate because I never really use that anyway. I mention the Suspend function because in the past with NM and cifs in the /etc/fstab file Suspend used to only work the first time, then every time after that the network would not reactivate and I had to reboot. Just in case anyone else is interested in that little tidbit of information. This seems to definitely be a Network Manager induced condition.

Well, 2 people reported in this very thread that moving wpa-ifupdown to S36 does not fix it. I think that's because of K16dhcdbd.sh. Name resolution is still needed when unmounting NFS drives.

The best solution to avoid messing up the unmounting issue for special cases as described by Reinhard Tartler 5 posts ago is to use a special unmounting script for cifs. People who have used the workaround described by luchio have never used such a special case scenario. Therefore it is much more prudent to leave the present scrips as they are and introduce a new script for cifs. This solution has been proposed before by Sander Marechal.

In case anyone cares, my initial testing using this method has been very successful so far, both shutdown/restart and suspend/resume are working as I expect. Would be possible to have Canonical officially embrace and include this script in the Ubuntu base packaging and close out this issue once and for all? In the interest of having a Linux deliverable that "just works" right out of the box it seems like this would be a strategic move to me. There's a little bad press further up stream here that I'd like to see turned around. In my opinion this is by far the best release of Ubuntu yet (I've used Intrepid since the Beta and have updated but never actually re-installed with the official version), and now it is 100% complete for me.

[Bug 211631] Re: CIFS/SMBFS shares not unmounted before network is shut down
The issue discussed here boils down to the fact that network interfaces can be brought down *before* network filesystems are unmounted thus leading to a long timeout. One option proposed was to move the umountnfs script earlier in the shutdown sequence. Doing leads to the possibility that running processes still have files opened on the network share. This is the reason why S31umountnfs.sh is run *after* S20sendsigs. Some packages have their shutdown scripts set too early in the boot sequence. These should be fix them rather then moving the umountnfs script earlier in the shutdown sequence. Another option suggested was to use the ifdown.d infrastructure. That means writing a script that is able to unmount network filesystems according to the interface been brought down. However the script should not unmount the remote filesystems when *a* network interface goes down but rather unmount them when the *corresponding* network interface goes down. What *should* be happening in all cases is that the network route is gone. Trying to send to it will return a no-route-to-host which can be detected and handled by the kernel. So either the route isn't being torn out when it should be, and we should fix that; or the cifs driver doesn't handle no-route-to-host, and we should fix that. Adjusting the timeouts or moving/adding init scripts shouldn't matter at all. -- CIFS/SMBFS shares not unmounted before network is shut down https://bugs.launchpad.net/bugs/211631 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

I also did the right thing and reported this bug in one of the reports that was marked as a duplicate. Yes it is frustrating to see bugs take so long to get fixed, and ultimately lack of a positive result teaches users to give up bothering to file bug reports. That's not a good thing, as it causes bugs to go unreported and impedes progress. In the big scheme of things, using Linux teaches you patience, teaches you to learn to live with disappointment, and teaches you to look on the bright side: I left Gentoo development many years ago because of problems like this. With that other distro, bugs would remain unfixed and some developers would deny that bugs exist and invalidate bug reports without fixing the bugs, just to buff up their bug closure statistics. Then users would fight to have them reopened, and the developer would immediately re-close it. It was like beating your head against the wall. The entire process of user reporting and developer invalidating would repeat itself over and over again in a never ending cycle. It evolved into a farce. Watching the Gentoo developers insist that the bugs don't exist can be quite amusing -- even though I have not used the distribution any more, I'm still receiving email updates regarding an rsync time logging bug that remains unresolved 5 years after I first reported it, and the same developer continues to close the bug reports every time that users re- open them.

One thing I only just figured out: if you are using the umountcifs script linked above, you also need to set the network as a system setting, otherwise it's pulled down when you exit KDE/Gnome and still leaves the umount hanging during shutdown/reboot. I made sure network-manager-gnome was installed, logged out of KDE, choose GNOME from the log in menu, and used GNOME's network manager to set the connection property.

[Bug 211631] Re: CIFS/SMBFS shares not unmounted before network is shut down
Quick status update/summary on this bug, because this thread is long and tends to discourage people that could solve it. The bug occurs on shutdown if you mount a CIFS share (using mount or /etc/fstab). In some cases, S31umountnfs.sh tries to unmount the network file system *after* the network has been brought down. CIFS doesn't handle so well having the network pulled out from under it, so it stalls the shutdown process for some time, but the shutdown finally succeeds. The most common case appears to be those using NetworkManager to handle the network interface (NetworkManager gets killed by S20sendsigs, before S31umountnfs.sh). If you are not using NetworkManager at all (and have your network defined in /etc/network/interfaces), the unmount will succeed. That's why this bug doesn't really affect Ubuntu Server systems. Also I would argue that you should not mount things system-wide while having your network up/down at Gnome session start (think wireless). Nautilus-based mounts seem like a better idea in that case. It's *not* simple to fix. There are lots of workarounds which will solve the problem for your use case, but which will also break it for other folks. The fact that workaround X solves the issue for you doesn't make it a proper update that can be applied to all other Ubuntu systems. Cutting the network filesystem before S20sendsigs for example may result in data corruption, which is arguably worse than an annoying delay at shutdown. The best way of solving this is to have CIFS (probably in kernel) better support having the network pulled out from under it. I haven't really found how we could do that, but I'll try to invite some CIFS specialists here. Another way could be to exclude NetworkManager from S20sendsigs and kill it properly at ~S35... constructive, technical comments welcome. It's true that the way Launchpad works doesn't help us in solving this kind of in-between-packages bugs (and most distributions won't be better than us). But bitching about it just makes developers turn to easier (and more rewarding) bugs to fix. ** Bug watch added: Debian Bug tracker #477498 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=477498 ** Also affects: sysvinit (Debian) via http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=477498 Importance: Unknown Status: Unknown -- CIFS/SMBFS shares not unmounted before network is shut down https://bugs.launchpad.net/bugs/211631 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Thierry, I just installed your ppa network-manager packages on Intrepid, and it's still hanging on shutdown (using wireless) with CIFS VFS errors. A fairly fresh UMPC install on a Dell Mini 9. I ran a continuous ping on the machine and network is unavailable nearly immediately after selecting shutdown from the gnome menu, after a bit I can then see the shutdown splash and a bit later I'm geting the CIFS VFS errors. Interestingly enough, even when I remove quiet and splash from the grub menu.lst, it's still not showing any shutdown messages to me, just the CIFS VFS errors and sometimes an apcid error. So it's impossible for me to tell the network manager is dying too soon. -- CIFS/SMBFS shares not unmounted before network is shut down https://bugs.launchpad.net/bugs/211631 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 211631] Re: CIFS/SMBFS shares not unmounted before network is shut down
A couple clarifications: 1) We really want the network file systems to be unmounted (or at least synced) before the network goes away. You do not want to risk losing file system data which has been cached by the Linux memory management layer. 2) If there is cached write data, we do want the file system to try as hard as reasonably possible (perhaps forever in the case of mounting with the "hard" mount option rather than the default "soft" mount) before giving up - the network which is down for a few seconds, may recover in most cases (where exactly we are in shutdown of the system may be hard to detect in this path in the kernel) 3) CIFS already does do the obvious - it does not attempt to send network requests in umount (SMB "tree disconnect" followed by SMB "ulogoff") if the session is already dead (the server implicitly closes "tids" and "smb uids" when the socket crashes). Write requests just prior to the umount getting to the kernel would cause attempts at reconnect, but simply from the kernel cifs driver perspective umounting should not cause network traffic if the session is already dead e.g. see this code excerpt from CIFSSMBTDis /* * No need to return error on this operation if tid invalidated and * closed on server already e.g. due to tcp session crashing. Also, * the tcon is no longer on the list, so no need to take lock before * checking this. */ if (tcon->need_reconnect) return 0; and similarly in CIFSSMBLogoff: if (ses->need_reconnect) goto session_already_dead; /* no need to send SMBlogoff if uid already closed due to reconnect */ -- CIFS/SMBFS shares not unmounted before network is shut down https://bugs.launchpad.net/bugs/211631 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 211631] Re: CIFS/SMBFS shares not unmounted before network is shut down
Things get even weirder, if I select logout from the gnome panel, network goes away, so I log back in as the same user, and network comes back as expected. But if I log out again, network stays up! Tried logging out again, network still stays up. I noticed, if I log out, and then back in, then after shutting down, I see the shutdown messages, I see my cifs mounts getting unmounted properly (no CIFS VFS errors) and then then the networking interfaces get deconfigured. Shutdown happens properly It seems at least for me, something is causing the network-manager to die the first time I log out, but then after that, it stays up between log outs. Can anyone confirm? Could this be some weird issue where the network-manager is not properly detaching from the controlling terminal or something of the sorts? So basically something is causing my network-manager to die and not show me shutdown messages if I don't log out and log back in first before shutting down...

[Bug 211631] Re: CIFS/SMBFS shares not unmounted before network is shut down
I think I also need to clarify something here. If you use NetworkManager with per-user settings (i.e. without the "system setting" checkbox checked) then the network connection is up only during your session. When you log out from your Gnome session, the network connection goes down. This is the default for desktops, and usually the case for wireless connections where the password is stored in the user keyring. So the whole concept of mounting any network filesystem system-wide at boot (in /etc/fstab) while your network will only be there during your Gnome session is flawed. Here are the sane modes of operation: (1) Not using NetworkManager, define a static network configuration in /etc/network/interfaces Then you can use /etc/fstab without any problem, shutdown will work without a timeout. This is usually used on servers. (2) Using NetworkManager in "system setting" mode Then you should be able to use /etc/fstab without a problem. At this point there is a bug in NetworkManager that makes it die before umountnfs is called. The version in my PPA solves this. Please test. (3) Using NetworkManager without "system setting" checked (per-session mode) Then you shouldn't be using /etc/fstab at all. The network will go down when the Gnome session stops. True network filesystem mounts require the network to be up regardless of the Gnome session status. You should use nautilus mounts instead (smb://server/share). Those will be unmounted before Gnome logout. I am trying to solve the bug in the (2) case here. If you are in the (3) case (and a lot of you probably are) you should either switch to "system setting" mode or drop usage of CIFS mounts in favor of Nautilus gvfs-smb mounts. -- CIFS/SMBFS shares not unmounted before network is shut down https://bugs.launchpad.net/bugs/211631 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

@Thierry Carrez: For use case #3, isn't that what the '_netdev' mount option is for? In my fstab, I always use '_netdev' for a network share; I think RedHat considers it a best practice. One could also combine that with 'noauto' and 'user'. The problem with gvfs-smb mounts is that non-gvfs aware apps would not have access to the network filesystem. In my setup, I also use gid=100 to mount network filesystems for all users (gid=100).

[Bug 211631] Re: CIFS/SMBFS shares not unmounted before network is shut down
OK ... doing a little more investigation it gets interesting to see what crazy things gnome does (you can also try clearing the dmesg log and then doing "echo 7 > /proc/fs/cifs/cifsFYI" before you logoff/umount and see what cifs operations are in dmesg) What I see is that the slow operations are repeated calls (presumably by gnome) to querypathinfo (stat) on ".Trash-1000" ... see below fs/cifs/inode.c: Getting info on //localhost/stevef/.Trash-1000 fs/cifs/cifssmb.c: In QPathInfo (Unix) the path //localhost/stevef/.Trash-1000 cifs has no way of knowing that this is useless and that we should ignore gnome's request In addition, running with umount.cifs (/sbin/umount.cifs is not needed in most cases unless you are doing user mounts/umount) you get a call to "statfs" (umount.cifs has to verify that this is a cifs mount and AFAIK there is no cheap way to do this in Ubuntu - and so we are stuck calling statfs to check the fs "type" field to make sure that we are in fact unmount a cifs file system - but statfs also unfortunately returns other information that requires sending a request over the network ... it would be very helpful if there were a way to query ... just ... the file system's type and not the other dynamic information that requires going to the server).

[Bug 211631] Re: CIFS/SMBFS shares not unmounted before network is shut down
@toobuntu:
The _netdev option tells the system (if it doesn't already knows it from the
fstype) that the filesystem should be considered mounted on network (and
therefore be unmounted in umountnfs.sh rather than umountfs).
@Steve Greci ("Seems when tracking down the cause of one bug, I encounter 3
more to that need to be fixed in order to solve it."):
I understand the feeling. That's part of why I said this bug is not so easy to
fix. Looks like your bug is solved in Jaunty though... so let's try if we can
completely fix it for that release :)
@Steve French:
Yes, there seems to be a major inconsistency between the way Gnome handles
files on network mounts vs. how NetworkManager handles the network. Thanks for
your analysis :) To mitigate the effects I agree we should hack umountnfs.sh so
that it always uses "umount -i". Since that script is always run as root I
suppose there wouldn't be any wrong side-effects ?
@Bart:
I agree that the different "network modes" are poorly documented (and checkbox
behavior in n-m-applet to switch between them used to be very buggy). I am
still not sure I got them right. I guess Alexander could confirm if what I said
in comment 88 is indeed how it works.
@Alexander:
I think most of the users with wireless reporting failure are in use case (3)
described in comment 88, since it's the default N-M mode of operation. However
I agree wpasupplicant needs to be fixed as well, for the case where you would
run on wireless with a system connection (is that even possible ?). Looking at
wpa-ifdown though, it appears it already has some support for sendsigs omission
(at least in Jaunty), so that might not be needed. I need more time on this.

According to http://www.debian.org/doc/debian-policy/ch-opersys.html#s-sysvinit, the Knn scripts are always executed before any S script. I cannot see how renaming S15wpa-ifupdown to S41wpa-ifupdown will interefere here. As this is an extra indication that I have not understood the problem completely, and given that this bug is already pretty heatly discussed, I will take extra care before considering any change in this matter. Looking further at it, it seems pretty obvious why renaming it to S36wpa-ifupdown does not fix it: unmounting nfs and other filesystems happen at S40. In order to fix this issue wpasupplicant has to be taken down after that. Which is a real pain in debian, since wpasupplicant is installed there in /usr/sbin, which might no longer be available at this stage.

Hi Thierry, I'm on jaunty, I've tried the package but I still have the same problem. On my jaunty install the problem is even worse, it doesn't get past the unmounts or perhaps it just takes extremely long, I have to hard-shutdown my laptop every time I shut down and forget to unmount these file systems first. In my opinion this is really a kernel problem, and a big one. If there is no route to the host (which is the case if the network is down), the cifs vfs should properly detect this and not wait for some timeout. And it *can* easily detect this: when the network is down and I do a ping, I also get "no route to host". I don't see any reason why the cifs vfs shouldn't be able to detect this as well. Also, your current attempt at a solution will only solve the problem when the network is still up. But what if I shut down while my wireless network is gone? For instance, when I've moved away from my home location with the laptop on or (probably) suspended? Or what if my wireless network simply shuts down by itself? It tends to do that. :-) I really hope that somebody will find time to look at a proper, kernel based solution.

In that case it seems that the only reason for the existence of the NetworkManager daemon is to perform the required privileged operations at the biddingI don't know *exactly* how NetworkManager works, but I'm under the impression that it only holds a network connection while the applet is running, i.e., while the user is logged in. This could be a security thing, because it gets the network settings from the user's settings, and also the authentication to a wireless network are taken from the logged on user's key ring. So it's actually quite logical that it would shut down the network at logoff, BEFORE any of the shutdown scripts run. (In that case it seems that the NetworkManager daemon is only there to do the required privileged work at the bidding of the nm-applet. And if the nm-applet disconnects due to logoff, then it disconnects...) Anyway, this is all just conjecture. I might have it all backwards.

My cifs file systems are all as read only as a read-write file system can be: I almost never write to them, I just mount them by default so that I can read from them (which I also almost never do), and also write to them when I want, which is also not a daily thing. So I almost always shut down in a situation where the file system has only been read from, not written to -- and the reads are usually also a long time ago. No reason at all to wait indefinitely! For reference, all my cifs file systems are mounted below /nas/..., and the following command: # lsof | grep nas shows nothing. No files open on the shares, and it's like that for most of the time. Still, my system hangs at shutdown. There's *something* fishy going on here. Do you know of any other commands I should try to figure out if there is some dirty data left for the cifs file systems, that somehow doesn't get written? Would it help to sync before I reboot from the GUI, so that all pending dirty data is flushed to the cifs fs?

Thanks very much for the detailed explanation. I switched to "system setting" mode and this did solve the problem for me. This option is very well hidden however, so this is probably one of the reasons why there are many users who use fstab in combination with per-user network settings. (The gvfs option is not suitable for me BTW because I access the mounts mostly from scripts. And also from KDE programs -- I'm not sure those can access gvfs. :-) ) I do still think that there is something fishy going on with the long timeouts while I have nothing open on the network fs. I admit that I'm applying the same kind of logic that people do actually use for things like thumb drives -- if you don't write to them (or haven't written to them in a while) then you can remove them without thinking. It's not *technically* correct, but it's only not technically correct because the system works that way. And then we are typically trying to make the users behave in a certain way to match the behaviour of the system, instead of making sure the system behaves as the users quite reasonably expect it to. :-) Personally I think that it would be very much in line with Ubuntu's "human" philosophy to try and make the system behave as humans expect it to, which in this case is that if they haven't written anything to the fs, then there's no reason to wait for the server. Steve's analysis might give some pointers to WTF is going on here...
