NAS folder not mounted after reboot & MPD stops running when external DAC switched off

[erivet1]

Hi,

I am using the rAudio 1 version 20210227 on a RPi3 model B. After several hours looking at various threads in runeaudio.com, I have never been able to mount any NAS folder via CIFS locally (although it works on my mac). However I am able to mount NAS folders via nfs but only manually through the /etc/fstab/ file (it does not work via the UI). By the way in Sources in UI, I have only Devices and File System Table, but not Mounts (as it appears to be in the User Guide). After rebooting RPi I have a red dot on my /mnt/MPD/NAS/xxx. To mount it I need to do 'sudo mount -a' in the terminal via SSH or a 'remount' in the UI. I tried different options in /etc/fstab/ such as defaults,auto,_netdev.

Does someone have some suggestions?
Thank you and well done for this nice work.

It works fine on my installation (a setup with a Raspberry based NAS with the music collection and a separate Raspberry with the raudio). Following startup of the NAS it needs, however, a little while (probably a minute or so) until the NAS' network address is "known" in the network. If I observe such startup waiting period, the raudio Raspberry has no problem connecting it at startup. But I thought about a suggestion to rern whether a regular "mount -a" command (like every minute or so) or a tleast a one-time repeat of a "mount -a" about a minute after startup of raudio would make sense.)

By the way (also suggestion to rern) - it would be great if raudio would not only allow for static IP for the NAS in the UI but also for host names (including such from a Windows network). Currently, entering host names is not allowed/possible in the UI.

As said above, sometimes the MPD stops running. With a systemctl status mpd command, I get this:

• mpd.service - Music Player Daemon

  Drop-In: /etc/systemd/system/mpd.service.d

And with the netstat -anp | grep 6600 command, I get this:

Today I made a clean install in my RPI 4 8GB and after hours trying to figure the problems I give up.
USB RAID is mounted, but library = 0.
MPD not running:

pacman -Q mpd; systemctl status mpd

mpd 0.22.6-1
● mpd.service - Music Player Daemon
Loaded: loaded (/usr/lib/systemd/system/mpd.service; disabled; vendor preset: disabled)

Process: 447 ExecStart=/usr/bin/taskset -c 3 /usr/bin/mpd --no-daemon (code=exited, status=1/FAILURE)

What can I do?

At this time I'm running without problems original Runeaudio in RPI 3 1GB.

@erivet1,
Try:
sed -i 's/1..10/1..30/' /srv/http/bash/startup.sh
(extend checking for NAS ready to 30 seconds)
Then reboot.

@yopmismo
Try:

• Disconnect USB drive
• Connect a USB thumb drive with a couple of albums
• Connect the USB RAID (wait for Library update to finish)

Thank you @rern
It worked, I never figured this solution...

Hi @rern,

Thanks for answering, I greatly appreciate. I flashed the SD and started with a clean install.
I sticked with ethernet connection, mounted the NAS music folder, and added your command.
I do see the change in the startup script.
Unfortunately I have to mount the folder manually after startup.
Any other suggestions?

Actually I found out when the MPD stops working. It is when I unplugged the USB cable on my USB DAC or I switch off the DAC.
I disabled the headphone output in boot/config.txt (dtparam=audio=off) but I still have this problem. It means that every time I switch on or off the external DAC, I need to reboot the RPi.
@rern I saw that you have a similar config with an eternal SMSL DAC, did you experience such bug?

[rern]

Now MPD runs with a single audio output at a time. No needs to disable the on-board one.

By default:

• I2S DACs - On-board disabled when setup.
• USB DACs - On-board still enabled. There should be at least 1 output available, when power off, for other functions and features to work properly.

[erivet1]

But even if I keep the headphone output enabled, the MPD stops working when I turn off the USB DAC. I do not think this is normal, correct?

[rern]

My USB DAC has never behaved the way yours did. Was it powered separately or by the USB port?

My RPi and DAC are powered by a linear power supply. It logged "under-voltage" event when rebuilt new database from my USB harddrive, powered by the USB port itself. Sometimes MPD died half way through.

See the System page if there is a "Voltage under 4.7V" line in Status section when MPD died.
