These services do not have any ordering dependencies which means that on shutdown they are stopped as soon as possible. If NFS mounts are present, system will hang on shutdown for prolonged time (it will eventually reboot, not sure whether this is done by kernel or systemd). The following is suggested fix. All network mounts automatically get dependency on network-online.target. So let's order network@if.service before network-online.target on startup, which ensures remote filesystems are unmounted before interfaces are stopped: [Unit] .. Before=network-online.target Wants=network-online.target Wants here is required for manual NFS mounts, otherwise network-online.target is not started at all. I have tested it successfully, including busy mount points. If we are OK with this approach, SR will follow.

It would be nice to fix the timeout properly so that e.g. if you shutdown after pulling the network cable it would work nicely. I suspect that means that when umount.nfs gets NETWORK_UNREACHABLE when trying to tell the server that it has unmounted, it should abort quickly. So maybe make the suggested change to network@if.service then assign it to me to get fixed properly. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Hmm ... only the switch sysconfig-network over to wicked bothers me as the old

network@.service

was part of sysconfig-network. Now we have no network@.service anymore but several wicked serivces

wicked.service

This is the "oneshot" starter/stopper, which provides "network.service" similar to network.service on 13.1 [which triggered network@ starts]. It pushes config to the daemons, waits a while for them to start and the rest is done/continues inside of them.

...

wickedd-auto4.service wickedd-dhcp4.service wickedd-dhcp6.service wickedd-nanny.service wickedd.service

All wickedd* service can be considered as one. "systemctl restart wickedd" restarts all of them. Stopping them does not stop the network.service (wicked.service) and does not trigger network shutdown.

...

Also I'd like to submit a fixed sysconfig-network for 13.1

Sure, when we have something that works, we should submit it. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

On my system the only way I could resolve it was to add "Requires=network@eth0.service" to /usr/lib/systemd/system/remote-fs.service, ensuring that the network interface is not taken down before the remote-fs.service is stopped (thus ensuring clean unmounting and quick shutdown without timeouts). This is a quick-fix for my system but is too system-specific. Network interfaces should not be shutdown before all remote fs mounts are closed but I'm not sure of the best place to handle this.
