Description Helio Chissini de Castro 2015-08-03 09:14:40 EDT
Network filesystems are schedule to bee unmounted after the network is shut down.

NetworkManager is already down and system keep trying to unmount nfs and samba shared for around 120 seconds per share.

Network filesystems should be unmounted before networkmanager.
Comment 1 Zbigniew Jędrzejewski-Szmek 2015-08-03 11:46:05 EDT
They should already be ordered so: network mount units are ordered after network.target, and NetworkManager.service is ordered before network.target. Shutdown is performed in reverse, so network mounts are stopped first, then network.target, then NetworkManager.service.

Can you show the output of 'systemctl show -p Before,After,Wants xxx' for xxx being your network mounts (e.g. some-path.mount) and NetworkManager.service?

Here we go, system is a fedora 22 x86_64

[root@tiefighter ~]# systemctl show -p Before,After,Wants NetworkManager.service
Wants=network.target system.slice
Before=NetworkManager-wait-online.service network.target multi-user.target shutdown.target network.service
After=systemd-journald.socket system.slice basic.target netcf-transaction.service firewalld.service

[root@tiefighter ~]# systemctl show -p Before,After,Wants /media/multimedia
Wants=network-online.target system.slice
Before=umount.target remote-fs.target
After=systemd-journald.socket system.slice network.target remote-fs-pre.target -.mount network-online.target
