[Bug 1577885] [NEW] 120sec delay during shutdown or reboot with still mounted cifs (via Wifi)

[Matthias Laumer]

Public bug reported:

Using Ubuntu 16.04 Desktop with Unity, used the same approach in 14.04
with no issue.

I prepare for mounting with the following entry in /etc/fstab my
Synology NAS :

//192.168.178.61/data /media/server/server_data cifs
users,uid=1000,gid=1000,username=xxxxx,passwd=xxxxxx,iocharset=utf8,sec=ntlm,noauto,_netdev
0

After login to unity, I mount it with a bash-script (mount -a) which is
called from ~/.config/autostart/myMounts.desktop

Doing this, and shuting down or rebooting lead into a very delayed
shutdown (round about 2 minutes) Pressing ESC Key, showed that the
process stops at the command "umount /media/server ..."

I have not tested if this also occurs when I am connected via ethernet.
I think it is because the (Wifi)Network is already disabled prior all
umounts are done.

This issue happens even if I type in a shutdown command into a Terminal
or if I choose shutdown form the menue, also if I use the power-button.

Failure can be avoided if I umount the network-drives manually previouse
to reboot.

Interim solution was, to create an alias for "shutdown" like "sh
/path/to/umount/script.sh && shutdown" in /etc/bash.bashrc.local.
