Public bug reported:
I have the following line in /etc/fstab:
192.168.1.5:/srv/nsf4/main /shares nfs
noauto,nofail,x-systemd.automount,_netdev,x-systemd.device-timeout=14,size=32768,wsize=32768
0 0
This works properly in the sense that systemd does not hold up the
system when booting, and it does mount the directory upon first access,
however the system hangs at shutdown in a manner consistent with systemd
shutting down the network before attempting to unmount the drive.
Indeed, even when the system is running, I can manually run
systemctl stop NetworkManager.service
and/or
systemctl stop network.target
and a call to
systemctl status shares.mount
shows that the mount is still active.
Finally, I will describe the debugging I have done to this point. First,
if I manually unmount the share before shutting down, it shuts down
immediately. Second, it should be noted that this does not in anyway
depend on using the x-systemd.automount option. The same thing happens
without automount (or fstab for that matter - simply manually mounting
an NFS share and shutting down results in the computer getting stuck on
the shutdown screen). I also tried adding additional items to the
Require= and After= lines for shares.mount, specifically I tried adding
network.target, NetworkManager.service, and wpa_supplicant.service. In
each case, I did observe that manually running
systemctl stop NetworkManager.service
(for instance) now did cause the share to be unmounted, however if I
shutdown the computer without manually stopping these services it would
still stall on the shutdown screen. I can leave it for over 10 minutes,
at which point I manually power it off.
