Trouble getting MPD db to update

[wlowes]

I am new to VoyageMPD and attempting to sort out anomolies with MPD DB.
I use WAV files ripped with EAC on a WDLivebook NAS. I have mounted the NAS with CIFS and have mpd.conf pointed to the NAS for most of its files.

music_directory "/music1/Music"
playlist_directory "/music1/MPD/Playlists"
db_file "/music1/MPD/mpd.db"
log_file "/music1/MPD/mpd.log"
pid_file "/music1/MPD/mpd.pid"
state_file "/music1/MPD/mpdstate"

Voyage sees the files and they all have RW privileges.

root@voyage:/music1/MPD# ls -l
total 1984
drwxrwxrwx 1 root root 0 Apr 13 2012 Playlists
-rwxrwxrwx 1 root root 6984 Apr 13 2012 bkmpd.db
-rwxrwxrwx 1 root root 6984 Apr 11 2012 mpd.db
-rwxrwxrwx 1 root root 1873479 Apr 14 2012 mpd.log
-rwxrwxrwx 1 root root 5 Apr 16 2012 mpd.pid
-rwxrwxrwx 1 root root 2180 Jan 2 11:06 mpdstate
-rwxrwxrwx 1 root root 0 Apr 11 2012 sticker.sql
root@voyage:/music1/MPD#


I can see the music_directory in GMPC. After booting up, MPD searches the directory for about 5 mins and then the directory structure displays correctly and the WAV files can be played. (sound is excellent).

2 strange anomolies.

First, MPD only sees about 75% of the WAV files. In some cases 100% of files will show, in others every other file is missing even thought it is on the NAS.

Second issues is the db_file never updates. It still contains the list of songs that were on the usb stick I first put in the ALIX to test sound. When I removed the USB stick and set MPD to use /music/Music,
It refused to update the Tag_cache file. I pointed MPD db_file my NAS directory it would not create a new db. So I copied the tag_cache file to mpd.db on the NAS. It still does not update the file. When I first boot VoyageMPD the MPD client sees the old mpd.db file contents. It thinks there is still the usb stick exactly as I used it that first time. After running an update that takes 5 mins, it sees the directory of the /music/Music directory.

Any ideas on what I would need to do to get MPD to update the db_file?

Any ideas why MPD only sees a subset of the files on my NAS?

The NAS is formated with NTFS. Some have suggested Linux prefers FAT32. Lots of posts suggest running mpc -createdb, but I understand this has been depreciated. I understand that mpc update should cause mpd to delete old entries from db file and create new ones. But no luck 😕

from the GMPC FAQ

"I've added music to my Music directory, but it doesn't show up in GMPC.
Edit

Did you have MPD update its database? You can do this in GMPC by selecting "Update database" in the "Server" menu. "

cheers

Thanks Ian
I have asked it to update in every possible way.
The db updated the first time when I was reading music from USB0. It still has that information. So when I first start MPD the directory appears as reflected in the db. I just can't get it to reupdate. The update runs and after 5 mins the directory shows correctly and I can play music. But the db or tag_cache as some call it has not been written. Permissions appear correct. Clearly it reads the db, but refuses to write it. I have gone in and edited the db manually to remove songs. This is reflected in GMPC but again MPD does not update to reflect the new music_directory. I remain baffled😕

Do you have all the necessary permissions set up for mpd to write inside the new /music1/* directory structure?

What I have done is kept the default Voyage mpd directory structure (/var/lib/mpd/*), and then mounted my NAS as /var/lib/mpd/music/nas.

BTW, after rescanning the database, it is better to use command line or web interface to reboot the box once - it will commit the changes to the disk before reboot.

Regarding the missing songs, did you mount your CAS with iocharset=utf8?

Good luck!
