OK. I want to thank you @ndowens and @Dudemanguy for your time.

I can't wait to test out iwd-suite66 once it's there!

Hope y'all enjoying your day wherever you are. Greetings from Poland! :)

EDIT:
I had this message the first time around when shutdown went well. I'll test it once again with the modified iwd script.

I just pushed new iwd-suite66, hopefully this will work. May need to do 66-enable -F iwd once you get it

Just to recap, this is the SOLUTION.

/etc/66/service/iwd
Code: [Select]
[main]
@type = longrun
@description = "iNet Wireless Daemon"
@version = 0.0.1
@user = ( root )

[start]
@execute = ( /usr/lib/iwd/iwd )

[stop]
@execute = ( umount -a -t nfs  )

after that you run
Code: [Select]
# 66-enable -t default -F iwd

As for the fstab error, now I'm not getting it, so it must've been a one-time-thing.

Dang that's a bummer that did not work. Maybe there's more to nfs mounts than I expected. In the meantime, we'll try to adjust the stop/finish scripts which is worth it anyway. Could you post the output of cat /proc/mounts with your nfs mounted? I'm not sure what nfs mounts look like in that file (so we know what to grep for exactly).

/proc/mounts
Code: [Select]
srv:/ /nfs/srv nfs4 rw,nosuid,nodev,noexec,relatime,vers=4.2,rsize=131072,wsize=131072,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=192.168.1.52,local_lock=none,addr=192.168.1.115 0 0

Rev 3 of iwd-suite66 uses the [stop] how you had it, so should work

I'm waiting for the mirrors to sync and once everything works, I'm going to mark this thread as solved :)

EDIT: DAMN IT. Now the system hangs. I don't know what happened since the last time. Let me do some more testing.

EDIT2: @ndowens so apparently, I was trying to
Code: [Select]
umount -t nfs -a
while I should be doing
Code: [Select]
umount -t nfs4,nfs -a

The latter option appears to work. Please account for it in the iwd-suite66 package.

BTW, I downgraded suite66 from gremlins to system, and did  MNT_NETFS=!no in 66-env -t boot -e $EDITOR boot@system

Thank you! :)

Thanks for clarifying, I removed suite66 from testing and will re-adjust the stop scripts

Hi guys!

I'm sorry to say this but the above solution does not work in my case, at least. It works when you manually run
Code: [Select]
66-stop iwd
but it doesn't work when you shutdown the system when an nfs share is still mounted.

I'm sorry to have misled you on this, but apparently I did stop iwd when testing it for the first time  :(  

I'll do more troubleshooting and I'll play around with the iwd script more, but still I would appreciate some more opinions on this from the more experienced suite66 users.

Best,
Matt

@mattz7 can you edit /etc/66/service/iwd and change umount -a -t .. to umount -f -a -t ... and 66-enable -F iwd and see if that helps

Thanks for the reply :)

Funny thing is it worked now, but let me double check, boot up the system once again, mount the nfs and shutdown again :P

EDIT:
OK, the second time it worked, too.

I'll edit /etc/66/services/iwd and delete the -f option, do 66-enable -F iwd and see if it doesn't work. If it doesn't work, it means you nailed it! :)

EDIT2:

So I reverted the changes in iwd, re-enabled the service, mounted nfs and shutdown the computer. Only this time, it worked too.

Sorry for all this misleading information, but seriously I have such a mindf*** right now. I don't know what has changed since the last time, but apparently now it works.

EDIT3: OK, not it hangs, so I guess I know what happened. The change needs a reboot for it to work. So my hypothesis on the spot is, the -f option really makes a difference.

What I'll do is I'll add the -f option again, re-enable iwd, power off the computer, turn it back on, mount the nfs share and power it off. This'll be the ultimate test.

As long as it works :)

BTW, do you know why the -f option would make a difference here? Because I don't get it.

I'll check the -f option a couple more times.

It is suppose to help a bit with hangs with nfs unmounts and such, but not guaranteed to do so. But I am adding the change to the scripts, to maybe help avoid this even more in the future.

Great news. I'm looking forward to you pushing the change to the repos.

Now I'm thinking, maybe the [stop] part is executed after the IWD process is killed. But then again, running 66-stop iwd manually unmounted the share even though it didn't have the -f option. I'm confused...

As for the testing, I checked the -f option after a reboot, and now shutting down works like a charm after mounting the nfs share.

A big thank you to y'all! :) 

EDIT:

@ndowens @Dudemanguy Alas, there is one more hitch. When shutting down from my KDE plasma desktop, so I believe through elogind, the shutdown process hangs.

When shutting down from TTY, the shutdown process is smooth like butter.

EDIT2:

Running
Code: [Select]
dbus-send --system --print-reply --dest=org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager.PowerOff boolean:false
also works. I need to do more research and testing and I'll get back to you with my findings if I get them.

EDIT3: So running
Code: [Select]
loginctl poweroff
also causes the system to hang while shutting down.

Re: shutdown/reboot hangs when nfs has been mounted

Reply #57 –
That's very odd. I always presumed that loginctl poweroff would simply just call the poweroff binary on your machine. So there shouldn't be any difference. Somehow something must be different with that call.

Re: shutdown/reboot hangs when nfs has been mounted

I always just use terminal to reboot or shutdown. Where did you use the dbus-send cmd?

Side note, I just pushed update elogind-suite66 package that cleans up a bit of it, though I doubt it helps in this situation. I updated mount-cgroups to do partly what elogind script was doing.

It seems that loginctl currently calls shutdown -h, not physically powering down the computer. You can use shutdown -p now to do that. I changed my sdmenu script (which I use as a shutdown menu) in my fork of dwm to do that.

I think the goal should be to eventually move away from loginctl as part of systemd anyway.
