Library update as a cronjob

[mibant]

Hello,
sorry if this topic has already been covered here, but unfortunately I couldn’t find anything in the search.
I have a Volumio primo to which a NAS drive with several 100 GB of music data (flac and mp3) is connected as a source.
The source changes continuously as I rip and add new CDs.
I don’t want to keep updating the library manually, is there a way to set this up as a nightly cronjob? I have SSH access; is it possible to start the update via command line?
Thanks a lot!

See;

Auto detect changes and rescan of library

Hi, Not sure if this has been suggested or even if this happens already. When adding new music to my mounted NAS, are you able to detect the change? If so then perhaps this can trigger an automatic rescan of that mount point. If not, then perhaps ability to add a scheduled rescan by the user would be useful. Many thanks for your consideration.

Thanks for the fast reply!
Seems to work, exactly what I was looking for! (and could not find )

Be aware of the downside.

If a library update is running and you shut down the system, you might loose all data or cripple MPD.

Thank you, I have read that. But I don’t expect any problems with it during a night-time scan, because there would have to be a power failure.

Sorry, additional question: ist there any log, which tracks these updates, or can it be enabled?
Apparently neither mpd.log nor another log I can see in /var/log are used. If in doubt, you should be able to see the status there.

the only thing I can think of is monitoring the pid:

volumio@volumio-allo:~$ ps aux | grep "mpc update"
volumio  10123  0.0  0.0   1984   436 pts/0    S+   14:10   0:00 mpc update --wait NAS/

volumio@volumio-allo:~$ pidof mpc update
10123

That’s right, that should also be enough. Thanks for your patience!
