Synology NAS > how not to re-build library every day

[AndyF]

Hi JetAir,

only a stupid idea - try to set a fixed IP-Address to runeaudio. If I switch to DHCP, my NAS sometimes is unavailable at startup. It seems, mounting occurs before runeaudio get a suitable IP-address.

regards, Andy

Dears, in a very advance I want to say big THANKS for your advises.
And additionally I want to say SORRY for the fact that I’M SO STUPID ((((((

How resolved > while checking answer on every your question and proposal, I realized the following:
• In the MPD settings screen, what is your 'Auto Update' setting? Enabled or Disabled?
>>> Here was the main trick. It was YES (because in the notes it was mentioned that this helps to have NEW/UPDATED files become visible).
In reality, based on my practice, this rebuilds library after every start up. And here was the issue. Now I put is as Disables and at least 2 rounds of ON/OFF it was OK.

And here answers on your questions and proposals. May be in the future it could help other colleagues in quite similar situations.

• Does MPD really completely forget the library on restart, or is it just very slow to refresh (i.e. several minutes)? There's a known issue - a workaround is here: rune-ui-is-slow-t6829-10.html#p28023
> Looks like YES,

• Do you Update or Rebuild the library?
> I was pressing both. I, honestly saying, don’t recognize what is the difference because it took the same time for both options.

• I assume you're using the latest version of Synology DSM (currently DSM 6.2.2-24922 Update 2 for both my DS212 and DS918+). Is the NAS generally responsive? Try installing something like foobar2000 on your PC, and pointing it at your NAS's music library - does the library refresh in only a few minutes? Do you have many other Synology apps running?
> Yes, I have the latest DSM
> It’s responsive. I used foobar to chech USB DAC’s input and it worked OK (can’t say perfectly, because sound was not as pure as with DIGI+ and with my previous Pioneer N-30)
> As for refreshment of the library > for Pioneer N-30 it doesn’t take time as all. Looks like it serves as DLNA client (correct?) and very fast reads all the folders.

• In DSM's Control Panel > File Services > Advanced, are SSDP and WS-Discovery activated?
> SSDP – YES
> WS – no as it mainly to have folders visible via Windows File manager, but I prefer to mount NAS folders as network disks.

• In DSM's Control Panel > Indexing Service > Indexed Folder, is the 'music' folder set with File Type 'music'?
> YES.

• Do you have the Synology Drive Admin Console installed on your NAS? If so, is 'Intelliversioning' switched off? How many versions are set for the 'music' folder? (from memory I recall the default number is quite high - 32 or something like that). Try reducing the number to 4.
> Not sure. At least I was not overloading NAS with additional APPS. The main purpose for my second NAS (414) was
> Become a source for music (and via mobile App in the car as well)
> Synology Moments to have unified storage for photos in initial resolution
> … so no any additionals tasks for it.


- The actions which you carried out show that the MPD music library is created properly and is correctly saved. The only way I know which would delete the library contents is to mount the NAS with no music files present. I suspect that somehow the NAS is mounted correctly, but its contents only become visible after a delay.
> Here looks it’s visible. At lease all mobile applications (DS File, DS Music, my Laptop) show good speed and full visibility of the folders) + I checked on previous equipment (Pioneer N-30 and Foobar)

- Just to eliminate other potential problems, could you look in the Sources UI, click on your NAS mount, then in the NAS Mounts UI click on 'Advanced Options'. Could you report the value shown in the 'Mount flags' field?
> Can’t find it now. Lost me notes. But I remember, that I it was abs std. I erased it, but then it was automatically restored to pretty default settings.

Hi JetAir,

You're very welcome, and I'm glad the problem is fixed. Please don't feel that you need to apologise - there's no such thing as a stupid question!

In my setup I have MPD Auto Update set to Off, and at least for me Rune starts up pretty quickly (with a library of almost 1,000 albums / 11,500 tracks). It's worth remembering that whenever MPD updates its library it has to work pretty hard - it interrogates the metadata embedded in every audio file it finds in the 'Source' location, and builds its own database describing where everything is, and each track's artist, composer, album title etc.. In reality it's not necessary to do this every time Rune starts up - in my own case I generally process music in batches (e.g. converting CDs to lossless library files), and I only do an MPD Library Update when a batch is finished.

I hope you enjoy Rune - it's a great product, and IMHO the best open-source network music system out there!

Peace and friendship,
englishtim

P.S. I see from your signature that you're a fellow Celestion SL6 owner. I've had mine from new since 1983, and I absolutely love them!
