Hi,
I'm using a Pi 3 model B, using a NAS to store the music, but for some reason I can't get the library to update it's self without manually doing it. I know what command to use via SSH but I can't create a cron job to implement the command.

Could someone help please?

Thanks
Nick

Have you tried the Auto Update setting on the MPD page, from the menu?

Ian

Yes I have tried that but it isn't working

Hi Nick.Moshulu,

i checked the autoupdate on my latest RP2/3 image and it works like it should.
There are several reasons for your issues:
- permissions
- mpd only checks changes in file date, so retagged files are mostly not detected.

I know what command to use via SSH but I can't create a cron job to implement the command.

Could someone help please?

I would do it the systemd way:
create these two files in /usr/lib/systemd/system

mpd-update-db.timer

Code: Select all

[Unit]
Description=Run mpd database update every 15 minutes

[Timer]
OnUnitActiveSec=15m

[Install]
WantedBy=timers.target

mpd-update-db.service

Code: Select all

[Unit]
Description=Run mpd database update every 15 minutes

[Service]
ExecStart=/usr/bin/mpc update

[Install]
WantedBy=multi-user.target

then run this command

Code: Select all

systemctl enable --now mpd-update-db.timer

with this command you can check the state

Code: Select all

systemctl list-timers

Hi Frank

When getting the list of timers, under next, left, last and past it just has n/a.

is that normal?

Thanks
Nick

Hi Nick,

please check:

Code: Select all

systemctl status mpd-update-db.timer

It is also possible that it needs a reboot.

Hi Frank

I have rebooted the Pi and it looks like the mpd isn't booting up.

any ideas?

Should I reinstall it completely and try again?

Thanks
Nick

Hi Frank

I went to dev and restarted mpd and that got that working again but it still says n/a.

I ran the code which says active (elapsed)

Code: Select all

systemctl status mpd-update-db.timer

Thanks
Nick

I sorted the problem.
Use this for mpd-update-db.timer

Code: Select all

Unit]
Description=Run mpd database update every 15 minutes

[Timer]
OnBootSec=10min
OnUnitActiveSec=1d

[Install]
WantedBy=timers.target

and use this for mpd-update-db.service

Code: Select all

[Unit]
Description=Run mpd database update everyday

[Service]
ExecStart=/usr/bin/mpc update

[Install]
WantedBy=multi-user.target

Hello,

I have two RuneAudio systems running at home and both have the same configuration (it would be great is they could share the same MPD database!) but yesterday I found that one system did not update its database. The only difference between the two systems is that one was rebooted and I saw that the timers did not start as expected:

Code: Select all

systemctl list-timers -all
NEXT                         LEFT     LAST                         PASSED  UNIT                         ACTIVATES
Sun 2018-03-04 19:26:53 CET  8h left  Sat 2018-03-03 19:26:53 CET  15h ago systemd-tmpfiles-clean.timer systemd-tmpfiles-clean.service
Mon 2018-03-05 00:00:00 CET  13h left Sun 2018-03-04 00:00:05 CET  10h ago shadow.timer                 shadow.service
n/a                          n/a      n/a                          n/a     mpd-update-db.timer          mpd-update-db.service


No matter what I did it did not triggered the mpd timer. Then I found that this argument in the mpd-update-db.timer did the trick:

Code: Select all

[Timer]
Persistent=true


Just do a system daemon-reload (and maybe a systemctl restart --now mpd-update-db.timer) and MPD is updating its databse as expected.
