ROON is updating the library every 24 hours on my Rescan is setup to Only at startup.
Before this version ROON was scanning my library at startup and then adds the new songs to the library. But now the scan is very slow, it is counting up and then counting down. Every time there is a scan there are new songs added to the library and my library was not modified.
My music library is on a Qnap NAS with about 96 000 songs
Since I have ROON my setup is unchanged, same computer et same NAS and I never had an issue before.
I tried removing the storage location and clean the library but the same update loop reoccurs.
Yesterday I recreated the storage location and started a new scan and today after 24 hours the scan was finished but the audio analyse was about done for 60% of the database and a new scan occurs. Now when I go in the clean up library section where the 3 items where reset to zero yesterday, now I have ‘Clean up 71765 files’… this number is changing with the new scan…
I don’t know what is the problem but there is something wrong…
Welcome to the forum! If you temporarily disable the QNAP as a watched storage location and copy a few media files over to your iMac (100-200 or so), does the same behavior occur for those files or is the issue limited to the QNAP share? It would be good to clarify this so we know in which direction to search, thanks!
Finally the bug is that I setup ROON to do the automatic rescan at startup but ROON force a rescan at every 24 hours.
To rebuild the ROON database and finish the background audio analysis it took 3 days because of the force rescan at every 24 hours. The rescan abort the audio analysis and the program have to rescan witch files are not analyzed and restart the process.
When everything is complete (about 2.5 days) the scan takes about 1h.
My ROON Core and my QNAP are both on the same gigabit switch.
But at every 24 to 48 hours ROON detects that all the library is (deleted ou modified).
I think the problem comes from the Multimedia Console App in my QNAP that is also scanning the same library of music. I don’t know if they changed something in the way they are scanning the files but it was ok in the past. Since then I have made several software and firmware updates on my QNAP. For now I disabled the App to see if everything is stable for a couple of days.
That didn’t solved the problem. ROON was not running for a couple of days and when I restarted it in the overview page the number of tracks started to go down from 96k to 300. Now the scan is adding the tracks back to the database but it will take like 2-3 days.
I don’t know what is wrong but it wasn’t doing that in the past with the same setup and hardware.
Does your QNAP NAS support a USB connection to the Core? If you could temporarily try connecting via USB instead of having it on the switch, I wonder if this behavior would be the same with the different connection type.
I’m using a TP-LInk C2300 router and a TP-Link TL-SG108 switch. The router, the iMac and the Qnap TS-453A are all connected directly to the switch.
The core is running on a iMac and I only start it when I need it, it seems that if I keep the core running all the time everything is ok (no delete of the database and rebuild after). But if I stop the core and start it again after a couple of days then there is a delete and rebuild of the database.
Thanks for this info, that’s interesting to note. Could you reproduce this issue and let me know the exact local time + date it occurs at? I wonder if logs would show any additional info, and I can enable diagnostics mode for your account after you let me know the time/date of occurrence.
Thanks for letting me know that timestamp! I have gone ahead and activated diagnostics mode for your Core and what this action does is next time the Core is online, it will automatically upload a log-set to our servers for analysis. Once these logs are received, I will request QA to review them to see if they contain further clues.
I started the core this morning at 6:25 and everything went ok.
I then stopped the core after the scan about 7:30 - 8:00.
I restarted the core a little bit later and force a rescan. (My auto rescan interval is at 24h).
This second scan reset my database and is still recreating the database at this time … 20:20
The folder with all my songs didn’t changed between the two scans.
