NFS keeps mounting even if not in use

I have set up a NFS mount in my fstab to unmount when I'm not accessing it with these settings

192.168.0.142:/mnt/tank/media/Downloads /run/media/Downloads nfs noauto,x-systemd.automount,x-systemd.device-timeout=10,timeo=14,x-systemd.idle-timeout=1min,user	0 0

I want to set it so that it unmounts the share and leaves it unmounted until I try to access it so that it's not constantly using resources on the server .

Even when not in use for some reason it keeps trying to mount. On the server you can see that after a minute it tries to unmount the server but then instantly remounts even though I'm not accessing it.

I'm not trying to access to share in any way I can think of so I don't know why it would keep trying to remount it. Is there something I need to set so that it won't keep trying to remount it?

Re: NFS keeps mounting even if not in use

I think you should be using autofs for this - https://wiki.archlinux.org/index.php/Autofs

@STREBLO

Are you sure some service or DE feature isn't trying to access the directory? Maybe see what happens without X running, particularly if you're running KDE or Gnome.

@paulkerry

AFAIK, systemd's automount serves the same purpose (more or less) as autofs. Is there a reason you think it would be better for OP?

I am running KDE but other than having it mounted nothing I can think of. Anyway i'll give that a try.

Re: NFS keeps mounting even if not in use

i have the same issue here. Really annoying is that everytime i open the devicemanager plasmashell freeze.

bugreport here:
https://bugs.kde.org/show_bug.cgi?id=355258

perhaps this is also important:
https://github.com/systemd/systemd/issues/2181

seems there's something to fix

None apart from checking if autofs works and automount doesn't.
