[gentoo-user] System hangs when poweroff with NFS mounted

[gentoo-user] System hangs when poweroff with NFS mounted

[Amankwah]

Hi all,
    I swithed to Gnome3 last week, and the systemd is needed by
gnome3.8, so I used systemd to replace the openrc now. Howerver, my
system always hangs when I try to poweroff.
    I have NFSv3 filesystem mounted via WiFi, it's managed by the
Networkmanager. so it seemed that the wireless connection was cut off
before the NFS was unmounted? I searched this problem and modified my
fstab line like this:

    NAS:/data    /media/NAS  nfs
    _netdev,x-systemd.automount,x-systemd.device-timeout=10ms,rw,soft,vers=3
    0   0

It's worked under the wired connnection, but the wireless connection
still hangs, Is there any thing should be changed? Or is it a bug?
    
I have to umount the NFS before poweroff everytime. Please tell me what can I do to
resove this problem?

Thx

I think it's a bug; systemd should stop NetworkManager.service only
after all remote filesystems have been umounted. Could you boot up
your machine after it hanged, and send the contents from "journalctl
--boot=-1". That will give us the logs from the previous boot; perhaps
we can see the problem.

I think it's a bug, but in the meantime (as a workaround) you can put
the following script in
/usr/lib/systemd/system-shutdown/nfs-force-umount:

---------------------------------
#!/bin/sh
/bin/umount -l /media/NAS
---------------------------------

Make sure the script is executable.

These are the output of the command on my system after hangs. but why
I saw nothing about my NFS directories?

I added the script to the path, and the system shutdown correctly, but
the time is too long, every NFS directory complained the timeout due
to and then umounted, maybe it took about 10 minutes for choosing the
shutdown under desktop to the system poweroff automatically.

10 minutes looks awfully long to me... and then I saw again your
fstab. You explicitly set a timeout of 10 milliseconds; but what if
there is a bug in systemd that parses 10ms (milliseconds) as 10m
(minutes)?

Just to try, change your fstab to set x-systemd.device-timeout=5;
without a suffix, so the time specified should be in seconds.

It seems that takes my more than 10 minutes, too. I don't know why.

And when I saw the shutdown screen, the WPA_** process was killed before
the the NFS umounted. Maybe it the reason why all of the NFS filesystem
umount process were running after the wireless connection closed.

Maybe that's a BUG?

Or an order error in the related service unit files. OpenSuse has
something similar in [1] and [2].

[1] https://bugzilla.novell.com/show_bug.cgi?id=849387
[2] https://bugzilla.novell.com/show_bug.cgi?id=857031

You can override a unit file in /usr/lib by creating one in /etc with
the same name. Perhaps playing with After= and Requires= in the NFS
units will solve this.

I haven't used NFS in a long time. Are you using the service files
provided by the packages, or you got them from somewhere else?
