[SOLVED] MPD issues with 0.1.5

[agent_kith]

1. Can you look at the file /var/mpd/scratch/mpd.conf, look for the line that says metadata_to_use, and confirm it's written as such:

File does not exist... Tried as user, and then sudo su
 nano   /var/mpd/scratch/mpd.conf   
File is empty for both..... very interesting.

My bad.. it's /var/www/scratch/mpd.conf (Have already amended previous post)

Just run something like

Code:

tail -n 30 /var/www/scratch/mpd.conf

Ok that works.. file exists and metadata is as required.
I removed my usb flashdrives with Music files, copied them off and reformatted the flashdrives then reloaded.
MPD 20 now starts and is populated showing all files...

However, when I try to play I get.....
The following error was encontered when sending the command:  play

500 Internal Server Error

The server encountered an unexpected condition which prevented it from fulfilling the request.

A more verbose version of the 'Connection refused" I was getting before...:-)  Hope it makes sense to you...

When I try to update database I get a similar output.....
So progress...closer and closer but no music yet... ;-)

Ok that works.. file exists and metadata is as required.

1. Connect a keyboard and monitor to your machine.
   
2. Reboot the computer with liveCD.
   
3. Select memtest.
   
4. Let the system run and wait for at least 1 pass to complete.
   
5. Does memtest report any errors?
   

If it passes the test, then do this. 

1. With just that  single offending file in /media/music (move the other files away from /media/music)
   
2. Do a database rescan.
   
3. Do you see a total of 1 file (or more?). Or did MPD crash?
   
4. Next select this song and play. Does it work?
   
5. Rescan the database multiple times, does it crash?

I doubt this helps in any way but this is the error message I got yesterday.  At the time Client 175 was showing a previous version of my library. Pressing play on one of those songs gave:

The following error was encontered when sending the command: play 500 Internal Server Error The server encountered an unexpected condition which prevented it from fulfilling the request.

Now while working fine and playing some Pink Floyd 

cat /var/tmp/stderr
client: [0] opened from 127.0.0.1:34042
client: [1] opened from 127.0.0.1:34044

MPD V20 crashed if music library is NFS-share directory.
I unmount NFS share and start V20. It's working.
I did mount
192.168.1.11:/export/Music to /media/music/NAS
and instant results - MPD V20 crashed:
exception: Failed to access /media/music/NAS/Music: No such file or directory
I found in my music library this file
lrwxrwxrwx   1 root     users      10 февр.  8 09:21 Music -> /mnt/Music
drwxrwxrwx+ 47 root     users    4096 февр.  8 09:21 Jazz
is likely he is the source of the problem

I was right.  

All because of that damned file   

Now V20 normally starts and scans music from Client175

[m@jor]

And another MPD V20 defect: run client Cantata 2.0.1 and M20 dies  
exception: Failed to open /media/playlists/[Radio Streams].m3u: No such file or directory
To solve the problem, place the file [Radio Streams].m3u (may be empty) in directory /media/playlists/

Memtest run for several hours and allgood.

Started MPD and everything works, database updates and files play. :-)

Looking back I think I see my problem .....oops.. I have several different players in different locations and move usb drives between them. Mostly these are formatted ntfs for compatibility accross the different os'

One os has problems with ntfs and I use a dedicated drive formatted vfat.

Somehow..my big mistake!... that drive had been put in the pool with the others...Thinking the drives were all ntfs I have been adding it as such to the music mount. Of course it fails to start, mpd throws errors and can't update.

Discovered this when I went back to LMS and did a database rescan and couldn't find any files !!!

Reformatted the flashdrive,added files and now mpd works as expected.

My apologies for imposing upon your time and efforts

I can not activate
Thank you!

That's supposed to be one of my walkthrough tweaks for the blog. Kind of let this out of the bag, but doesn't matter as I havn't written it yet .

So.... From the responses so far, what I can gather so far is, I still have no idea In my home lab, I have tried NFS, CIFS, and direct access... All worked and played fine..

So far, it's either - missing playlists, missing folders, problem files that will cause the crash.. What I don't know is if this is a MPD issue or something else.

Until I can find out what's going on, when MPD crashes - check the last lines of /var/tmp/stderr and fix whatever it says. MPD shouldn't just crash like that.. I'd have to dig into the codes and see why it's not handling that gracefully.

For folks who are using MPD and having problems. This may be resolved in 0.1.5a firmware. Please download that firmware and test if everything is working as expected.

If there are no reports of failures in 2 weeks from now I'd just assume this issue resolved and spin up 0.1.5a.
