[Bug 211631] Re: Network is brought down before network filesystems are unmounted (CIFS timeout at shutdown)

 

Is the solution described in comment #143 and comment #147 really the
correct one?

In short, that means dbus always stops on the event deconfiguring-
networking, which is emitted when "/etc/init.d/networking stop" is
called.

In other words, whenever "/etc/init.d/networking stop" is called, dbus gets killed.
That has a nasty effect: when dbus stops, gnome-settings-daemon crashes and that means the desktop theme is lost.

Please see bug #868095 [1] and my comment #3 on that bug.

VMware Tools does this all the time (calling networking stop) when
suspending the machine. That means you are guaranteed to get a horrible
looking (and not completely functional) desktop whenever you resume your
VMware session.

That also happens if I simply restart the networking service:
    /etc/init.d/networking stop
    /etc/init.d/networking start

    (Of course, because this chain reaction that leads to gnome-
settings-daemon death starts on "networking stop")

In conclusion, this seems to be a serious issue. I wonder if that is
happening with more people besides myself and the other fella on bug
#868095.

Bug description:
  IMPORTANT: this bug has enough information; please don't post
  _anything_ unless a developer asks for specific feedback! By posting
  to this bug you only make it harder for a developer to spot the gem

  I installed smbfs,and then put some entries into /etc/fstab, so they automount on startup. An example of this is here:
  //<ip address of nas box>/<share name>  /home/hamish/<directory name>  cifs  credentials=/home/hamish/.smbcredentials,file_mode=0777,dir_mode=0777,uid=1000,gid=1000  0  0

  ** note the use of "cifs" in the lines above **

  (The username and password are in the .smbcredentials file)

  On startup, for each entry in the /etc/fstab file, I get the following in dmesg:
  [   70.495504]  CIFS VFS: Error connecting to IPv4 socket. Aborting operation
  [   70.495569]  CIFS VFS: cifs_mount failed w/return code = -101
  But the shares are mounted, and a nautilus session opens up (which is also annoying...)

  Also logging off with CIFS shares mounted in /etc/fstab, it sits with an error message:
  CIFS VFS: server not responding
  CIFS VFS: no response for cmd 50 mid <this number changes>
  And takes about 2 minutes to timeout. This also happened with Gutsy

  Should the timing of the mounting and dismounting be changed so that
  it works? It is related to the starting of network-manager and CIFS
  shares trying to connect on startup *before* the network is up, and
  dismounting the shares *after* network-manager is stopped.
