Library Scan

[Jedich]

Hello.
The folders are no longer updated automatically. At first, the automatic update worked perfectly. In the meantime, I installed Jellystat, which also works great.

After adding new things to various folders, I noticed that Jellystat no longer automatically updates the folders. I don't know if this has anything to do with Jellystat.

I have to run the scan myself, after which all folders are up-to-date.

Is there a script or an option that starts the scan hourly or every 6 hours?

Or do you know what might be causing this?

Runnung Jellyfin 10.10.6 on a Docker.

from JF Media Player for Mac:
admin/dashboard/advanced/scheduled/library/scan media library.
hasn't worked for me for a while either.

Is your media in a network share? Or a directly attached drive?

[Jedich]

@TheDreadPirate
Who do you mean? If me:
Its "directly" attached drive. " because JF is running in a Docker on a NAS where the Media is stored.

A manually Update works fine so far. The Prob is that JF doesn't Update the Librarys itself.

Did you disable the scheduled task for library scans?  By default it runs every 12 hours, but that can be adjusted.

Dashboard > Scheduled Tasks > Scan Media Library

This should behave exactly the same as "Scan all libraries" on the dashboard home.

Thanks. There was a sheduled task, that sould scan all Libraries every 12hours. Not sure if that works. I deleted this shedule and make a new one which should scan the Library every 6hours now. Will see if this works.

[Jedich]

Nope, even the new Shedule doesn't work:

Can you share your jellyfin log via privatebin.net?

Code:

[2025-04-01 09:01:52.040 +00:00] [ERR] [141] Emby.Server.Implementations.IO.LibraryMonitor: Error watching path: "/media2/02-Filme-Mehrteiler"

System.IO.IOException: The configured user limit (128) on the number of inotify instances has been reached, or the per-process limit on the number of open file descriptors has been reached.

Hope this helps.


" The configured user limit (128 ) on the number of inotify instances has been reached, or the per-process limit on the number of open file descriptors has been reached " - i think thats the reason. i dont know what this means.

inotify is the mechanism that "real time monitoring" in Jellyfin uses, or any app with similar file monitoring functions, to determine when a change occurs to initiate a library scan on that item.

Network file systems severely rate limit inotify, though the limit is usually configurable to a degree. Once you hit the limit, Jellyfin then has to access every file and folder to check if they have been changed. Which is, obviously, much slower than using inotify.

If you have real time monitoring enabled, you should disable it.

Additionally, you should disable the startup job called "Cleanup collections and playlists". Dashboard > Scheduled Tasks > Cleanup collections and playlists. Remove the startup trigger.

That job can significantly delay startup if you have a very very large library on a network share.
