[SOLVED] Update library hangs unpredictably while scanning SMB share on a Fritzbox router

[s_mury]

Hi all,

I just updated my RPi4 to 9.2.4 but the library update/regeneration hangs after some number number of tracks in the sense that the circle keeps spinning and no more files are added (but the system is not frozen). Using

Code:

moodeutl --mpdlog

I can see how far it got. It's not the same place every time (after restarting and re-creating the source). Thus the problem does not appear to be with the files themselves. I also have a Pi Zero with its most up-to-date version of moode and it loads the library just fine.
The source is a SMB share of a usb stick in my Fritz.box router.
I reformatted the sd card and checked for bad sectors on Windows by creating a Fat32 partition before imaging with the Pi imager but didn't find anything.
I don't see anything unusual in the log apart from some thumb gen errors for some files that the library update doesn't even reach. It's on my list to fix those.

Code:

The library update stops much earlier. Most music is in mp3/ARTIST/ALBUM/.. (there is also 'Philip Glass'/ALBUM/.. that is searched afterwards) and it only got as far the 'C's. That's actually the furthest it has gotten.

My best guess is that the sd card has problems but any suggestions would be very much appreciated.

[Tim Curtis]

Very odd.

Some things to try:

1. Run a long ping test from the Pi to the NAS. When you examine the stats look for really high mdev (standard deviation), super long rtt's, lot of retries etc. This would indicate a network issue.

2. Install the tree command and check the permissions on the remote directory tree. MPD needs at least read access to the files and read+execute access to all containing directories.

Code:

sudo apt-get install tree

tree -p /path/

3. Check the permissions on the directory and files following the last directory indexed by MPD

Code:

ls -l /path/

4. Try a fresh 9 image on a new SD Card.

Hi Tim,


I just pinged it for 370s and got a low mean+/-dev =4.3+/-0.7. The slowest ping was 12ms.

The permissions also seem fine.

I also just confirmed the image SHA-256.

It must be the sd card. That's my second to fail on the same Pi. It's a Sandisk Ultra 16GB. I'll have a try another brand.

Try surveillance-grade cards. I've been using WD Purple QD101 cards for many years and no issues.

I've used Sandisk Ultra for my players for years with no fails. If you've had another card fail in that Pi, is it worth considering if the Pi might be at fault? Maybe the SD card slot is damaging the card?

I consider that a high failure rate for uSD cards. I’ve used SanDisk and Samsung cards for years and had only one fail for reasons other than my own stupidity.

Are your cards genuine SanDisk? Are you using an official RPi power supply? (Probably, but I have to ask )

Unfortunately, MPD is a lousy debugging tool, since mostly it just reports the last file it succeeded with. In any case, it’s curious that your Pi Zero with its old release of moOde is reading the whole library.

Your might want to look at the system journal (journalctl with its various options) to see if there are any suggestive errors or warnings. (I’m away from my systems so can’t post any examples.)

BTW - you don’t have to use a uSD card to contain moOde. I prefer using stubby USB flash drives like the 16 GB SanDisk Ultra Fit. It’s only 7.50USD list, very robust, and easy to flash on any host at hand without searching for an available uSD-to-USB card reader (which always go missing just when I need one. I blame this on my cat.)

Regards,
Kent

PS - I see Robert beat me to it. Next time I won’t stop midway to brew a coffee!

Thanks for the tips.

I am using the official RPi power supply and genuine Sandisk cards (from Amazon).

I just formatted it as Fat32 and ran h2testw, which writes and reads from every sector of the drive. It found no errors.
So I imaged again but the same thing happened as before.

I need to order a new drive (this time, I'll try usb) and test again.

So the problem may have something to do with Samba and my router vs moode. I see these errors using journalctl

I'm google searching but haven't found out what's going on yet. Interesting the searching for "kernel: CIFS: VFS: bogus file nlink value 0" brings up people with Fritzboxes.

I previously had an issue that I needed to add noserverino in the mount settings to get samba version >=2 working

[TheOldPresbyope]

“FritzBox” has come up a number of times in the forum but we in the USA have no experience with their products.

Even though some of my routers of old could provide SMB access to a drive I prefer setting up a separate server but that’s just me.

Good luck.

In Library Config > Remote NAS Source you can see the default Samba mount flags

Code:

ro,noserverino,cache=none,dir_mode=0777,file_mode=0777
