[Pkg-samba-maint] Bug#772914: related bugs and forum discussions

[Jeremy Schneider]

same problem here on a brand-new, pristine wheezy install.  i have not
yet found a clean workaround that works on my newly installed system.

Peter Nowee reported this same problem against the initscripts package
- seems there are three open bugs which might be related (477498,
516733, 431966) and two debian forum threads on this same problem.

Subject: Re: Shutdown & Reboot scripts try umount CIFS but CIFSD is killed first
Date: Mon, 14 Jul 2014 23:38:01 +0200

Hi,

I think this 7-year-old bug affects my fresh and up-to-date install of
Debian Wheezy. My CPU is a AMD Athlon XP 2200+, so I'm on
i386-architecture, not amd64. I'm running wpa_supplicant and
NetworkManager to connect to wireless, and made an /etc/fstab entry
for a cifs network mount. On shutdown or reboot, the system hangs for
a long time (probably five minutes) between:

...
stopping enhanced syslogd: rsyslogd

  and

CIFS VFS: Server bigbee.local has not responded in 300 seconds. Reconnecting...
...

See links below to forum reports of other users running into this
problem on Debian Wheezy and Ubuntu. Workarounds commonly suggested
are:
- Manually changing init-scripts or their priorities to ensure
umounting before the network goes down, or
- Avoiding the use of auto-mounted network shares, or
- Using /etc/network/interfaces instead of NetworkManager.

In 2011, Mike Perrin on the Ubuntu bug tracker suggested this problem
had to be solved in NetworkManager, so he filed a bug report upstream.
His report was marked duplicate at the time, but the original bug
(that his report was a duplicate of) was fixed last month. The fix got
included in the recently released NetworkManager 0.9.10:

"The NetworkManager dispatcher got some enhancements too.  It now has
a "pre-up" event that allow scripts to execute before NetworkManager
announces connectivity to applications.  We also added a "pre-down"
event that lets network filesystems flush data before the interface is
actually disconnected from the network." - Dan Williams,
NetworkManager developer, June 20, 2014.

I see that unstable currently has a package for network-manager
0.9.10. I'm running stable here, so I cannot check if this solves the
problem, but perhaps someone else can?

Regards,
Peter
