If I have a CIFS mount in my fstab it mounts fine after boot, but when I shutdown or restart the system hangs for a few minutes. It appears systemd isn't unmounting the the network share prior to disconnecting the network, which causes the hang. The only workaround I have is to manually unmount the share first. I have searched all over the internet and Arch Forums to find a solution for this annoying bug. The only thing left to try is creating a rc.local.shutdown.service as someone recommended. I feel like that's a hacky solution. Here is the entry in my fstab: //10.10.0.10/Music /mnt/Music cifs uid=j_r0dd,credentials=/etc/smb.auth,x-systemd.automount 0 0
Hmm, if you drop the automount bit for it, does it work correctly then?
No. Same thing. I tried autofs and the same issue. I just switched to KDE and there is an option to run shutdown scripts. I added one to run "sudo umount -t cifs -a -f -l" and added myself to sudoers to execute umount without a password which does the trick for me. I'm not sure if the behavior is the same for NFS shares because I have none set up to test. The shares are being mounted after there is a network connection so it would make sense on shutdown to do the reverse and unmount them before the network service is shutdown.
Hmm, I wonder if 0c08f5cde749bd2818475e487109cd0d413452df fixes things for you? Could you test?
Sorry, I somehow missed the email notification. If that patch is in 198, the issue is still there.
I just switched to NFS and I do not have this issue anymore.
I'm also having this issue. https://www.samba.org/samba/docs/man/manpages-3/umount.cifs.8.html specifies that the -f option can be passed to umount. Strangely enough, with -f the unmount process still seems to be blocking (even though the device is unmounted instantly).
I'm having the hanging issue with systemd 207-5 and 3.11.1-2-ARCH x86_64. System crashes (become unresonsive requires hard reset) when shutdown or restarted. On restart the boot partition require fsck do to improper closure. Stopping requires unount /dev/sdf1 ; sync ; poweroff -f No such problem with i686 laptop.

systemd side of the problem should be fixed in http://cgit.freedesktop.org/systemd/systemd/commit/?id=7700945. The issue that cifs mount cannot be forcibly unmounted probably remains. Feel free to take it up with fuse people or kernel people.
