[PROBLEM] UI Freezes with USB disk connected, eventually stops working

[toboli]

I have RPi 4B 2GB RAM, original power supply, 8GB SSD with moode 9.1.3, 1TB USB SSD disk, and Tone 1 DAC. While everything worked perfectly for a couple of weeks, now I am experiencing serious issues.

When I listen to the radio, it works normally. When I try to play something from the USB disk, the UI freezes for approx 50sec. Sometimes it plays something, sometimes it does not, but from the trace on the UI it looks like it is playing something, however, there is a silence. Most recently, I am not able to use USB disk at all. I tried to clear library cache and re-generate music database and reboot several times. While this partially solved the problem before, today I am getting this Alert:

Alert
Failed to decode /var/lib/mpd/music/USB/musicSSD/Monkey Business/2000 - Why Be In When You Could Be Out/03 - Party Shit.flac; Failed to open '/var/lib/mpd/music/USB/musicSSD/Monkey Business/2000 - Why Be In When You Could Be Out/03 - Party Shit.flac': No such file or directory



I have to mention that this is exactly the same experience I had with v8.3.9., when I was able to run moode for about 2 months when first issues observed. Shortly after the moode streamer was completely dead.
Because I thought it might be a HW issue, I bought everything new (RPi, SDcard, power, USB SSD).

Could somebody help me, maybe I am doing something wrong or maybe using moode in a wrong way (UI is challenging and I did not find any user guide)? What is the default UN PWD for the Web SSH, maybe I could find something in the logs.

I would bet on the SD card...

I've several PI devices and never had an issue with one of them. My PI B is running since 2014 24/7. Every 2y, I proactively replace the SD card. So, the hardware is quite stable.

My moOdes are running at least 10h/day on PI4s with the original PS and SSD boot. Albums are stored on a PI4 exposing an SMB mount of a 2TB SSD. None of this gave issues.

But... My team used to use PIs for demos, and we suffered on regular basis of broken SD cards. On my PI4 running moOde, I got this once after +/- 1y. This is what made me deciding to go for SSD boot.

The Download page at moodeaudio.org has links to the Setup Guide and Quick help (which explains WebUI navigation and special functions).

The symptom you report "...No such file or directory" suggests the USB drive may not be getting enough power and has dropped off the bus.

To me it looks like the SSD gets disconnected / unmounted. Usually a power supply issue.
Anyway, I too have a Pi4B with 4GB ram, original power supply, and an external (samsung) 1TB SSD - 2/3 full, but never experienced a problem.

ETA
My Pi is on 24/7, although I do restart it once every two or three months; I switch it off only if I happen to be away from home for more that two days.

To check power supply issues, via a ssh terminal you can do:
vcgencmd get_throttled     The response should be "throttled=0x0"
dmesg -T    Look for "Under-voltage detected! (0x00050005)"
