Can not make MPD rebuild library

[number9]

This is on a Raspberry Pi.

I was having a problem a while back where I could not get MPD to rebuild the library after I made a network mount change. (I moved the server).

Ok, so I formatted the SD card and installed RuneAudio from scratch. I then upgraded with the nightly build. I then added my mount back, which it accepted and from the command line I can see the network mount (NFS). When I go to "Menu" -> "Sources" and click on the large "Rebuild MPD Library" nothing happens. I have left it on for days, and no songs will be added.

As a note, I know the NFS server works as I can mount it from any of my other linux machines. Again, I can go to the command line and see the network share and see the files. For example, when I type "mount" at the CLI, I see my NFS server:

192.168.169.8://mnt/space/share/audiobackup on /mnt/MPD/NAS/AudioBackup type nfs (ro,noatime,vers=3,rsize=16384,wsize=16384,namlen=255,acregmin=1,acregmax=1,acdirmin=1,acdirmax=1,soft,proto=tcp,timeo=50,retrans=2,sec=sys,mountaddr=192.168.169.8,mountvers=3,mountport=33160,mountproto=udp,local_lock=none,addr=192.168.169.8)

if I do an ls on /mnt/MPD/NAS/AudioBackup I see the files.
df -h shows:
192.168.169.8://mnt/space/share/audiobackup 917G 680G 191G 79% /mnt/MPD/NAS/AudioBackup

But again, when I click on "Rebuild MPD Library" I get nothing and the machine does not start doing anything (checking with top, ps aux, etc, etc).

debug info

How can I manually force MPD to rebuild the library?

Thanks.

[root@runeaudio ~]# mpc update
Updating DB (#1) ...
volume: 88% repeat: off random: off single: off consume: off
[root@runeaudio ~]# mpc listall
[root@runeaudio ~]#

I will also note, when I do the mpc update command, nothing happens (e.g. if I have another terminal open and am running top or "ps aux" I see no new processes spawned after an update). Shouldn't it be going off and reading through the dirs building the database?

As for the "What do I expect" question, I expect to see the spinning wheel while updating in the bottom, but that is not what happens. Again, this was working, but I formatted and reinstalled and updated and now it does not work. I find it most odd that I can see the songs on the CLI. The NFS share is mounted, and in fact I can ls the dirs and see the music, but it is like MPD is not updating.

Thanks.

OK, so I ditched the NFS idea, and setup a samba server on the server. This seems to have worked. I am not sure how to fix the NFS problem, as there are built in users on the server at the same UID as the mpd user on runeuaudio (and I would have thought that runeaudio would have moved the UID to something more reasonable like 1000+)... still, even setting anonuid and anongid settings in the nfs server would not fix the permissions problem. I find it odd that it worked the first time. Still, CIFS/Samba seems to be working for now.

I would suggest attempting to fix the nfs problems, as it is most useful (particularly since it is an option). Thanks.

Hmmm...after rebooting the raspberry PI, I have no sound on the amp. Looking at the UI, the song appears to be playing....but not sound at all

Changed the MPD configuration to use root again, and now I have sound. I guess it makes sense: mpd user still does not have O/S access to the NFS mount, so it can actually read the media. At the same time, library is built and the player shows progress while "(not) playing" the file
I'll leave like this for now as the main important thing is I'm listening to good music while working.

Hi, I am brandnew here and have a big problem:
I can't rebuild the mpd library, no spinning wheel and nothing happens.
I have a hdd with about 600 cd's with a simple folder tree.
Before I was using Volumio 1.55 and had no problems with scanning the library.
I tried the command with Putty: mpc update for manual update but get the prompt "connection failed"
Very a pitty because I love Rune because its the only one with good Spotify features.

Please can somebody help me

If I have to work with linux commands please use donkey language
