Shutdown is very slow : Raspberry Pi • RuneAudio Forum

by **Elliott B** » 15 Jan 2014, 19:43

Shutting down this my Raspberry Pi running RuneAudio takes around 4 minutes. How can I troubleshoot this?
I read here to enable debug options:

Code: Select all: systemd.log_level=debug systemd.log_target=kmsg log_buf_len=1M enforcing=0

but I don't know where to type that.

I was reading the same article today! This point in particular:
http://freedesktop.org/wiki/Software/sy ... eventually
We are aware of the problem but we still didn't fount a satisfatory solution. It seems we are not the only ones to suffer this weird behaviour:

PS: Elliott B, you already are our most prolific bug reporter

Just let me tell you that your cooperation on this is really appreciated. Thank you and keep it up!

I did some tests in my custom archlinuxARM/mpd distro. I also suffered from slow shutdowns. I decided to replace netctl with systemd-networkd. The change was extremely easy and the configuration is as easy as netctl was.

After this change, boot is faster and shutdown is finally as it should be.

Hi,
also here very slow shutdown.
I've activated the debug and I've found a lot of errors like:
.....
Failed to send unit remove signal for <.....> Transport endpoint is not connected, any ideas?

Hi ab.eccolo,

without more information it's very hard to help.

- device (RP1, RP2, Odroid, Cubietruck)
- shutdown via user interface UI or via console?
- updates installed
- is it a new installation or a older one?
- free space on sd card (df -h)

Thank a lot Frank, you are right, without any information is not simple:-)
So,
-device -> raspberry 2
-shutdown -> i use a ATXRaspi board to shutdown the raspberry, so I've enabled the rc-local service in order to run in background a script that execute "systemctl poweroff" if I press the power button.
-yes update rune ui instelld
- new installation (if with my modifications can be called fresh instalation again..... :-)

Thanks again for your support

EDIT -> I've expaned the partition, new df:

EDIT 2 : as workaround to poweroff the runeaudio in the script I've set instead of systemctl poweroff:
sync ; sync ; poweroff -f

I know that is not the best way to shutdown a distro, but for now works...

@tux, is there any tutorial in order to set the modification on netctl? ( I don't still know very well systemd ....)

Hi ab.eccolo,

thank you for the detailed information, now it is clear what your problem is.
Also your topic title is a bit misleading, because shutdown triggered from the UI works.

What is the best way to shut down RuneAudio?
Here a explanation how it's done in Rune:
- stop mpd
- stop spopd
- stop nginx
- unmount the shares

Code: Select all: mpc stop systemctl stop nginx sleep 1 systemctl stop mpd systemctl stop spopd sleep 1 export DISPLAY=:0 xset dpms force off sleep 1 umount -aft nfs umount -aft cifs

https://github.com/RuneAudio/RuneUI/blo ... e_shutdown

So please try to add this to your shutdown script, or just call rune_shutdown from your script.
