HawkXP71 15 Posted October 7, 2021 Share Posted October 7, 2021 DSM 7, Synolology 918+ My libraries dont seem to update when new media is added. Ill drop a couple of new MKV files into appropriate directories, and until I manually "Scan Library Files" the new media isnt picked up. I do have "Enable Real time monitoring" checked. What should I look for in the log file? Or do I need to enable a debug flag to help track this down? Link to comment Share on other sites More sharing options...

HawkXP71 15 Posted October 7, 2021 Author Share Posted October 7, 2021 Going through the thread now. Thanks. I followed your thread for migration to DSM 7, this should probably be added to the information there. I am not seeing any inotify type messages in the log, but Ill update the inotify config Link to comment Share on other sites More sharing options...

HawkXP71 15 Posted October 7, 2021 Author Share Posted October 7, 2021 I did a reboot of the Emby server (not the NAS box) to confirm I was getting inotify messages, and I was 021-10-07 09:08:06.241 Error LibraryMonitor: Error in Directory watcher for: /volume2/video/Movies *** Error Report *** Version: 4.6.4.0 Command line: /volume2/@appstore/EmbyServer/system/EmbyServer.dll -programdata /var/packages/EmbyServer/var -ffdetect /var/packages/EmbyServer/target/bin/ffdetect -ffmpeg /var/packages/EmbyServer/target/bin/ffmpeg -ffprobe /var/packages/EmbyServer/target/bin/ffprobe -nolocalportconfig -ignore_vaapi_enabled_flag -pidfile /var/packages/EmbyServer/var/EmbyServer.pid -updatepackage emby-server-synology7_{version}_x86_64.spk -noautorunwebapp Operating system: Linux version 4.4.180+ (root@build15) (gcc version 7.5.0 (GCC) ) #41890 SMP Thu Jul 15 03:43:42 CST 2021 Framework: .NET Core 3.1.13 OS/Process: x64/x64 Runtime: volume2/@appstore/EmbyServer/system/System.Private.CoreLib.dll Processor count: 4 Data path: /var/packages/EmbyServer/var Application path: /volume2/@appstore/EmbyServer/system System.IO.IOException: System.IO.IOException: The configured user limit (8192) on the number of inotify watches has been reached, or the operating system failed to allocate a required resource.

kaj 146 Posted October 7, 2021 Share Posted October 7, 2021 @HawkXP71 You should make a scheduled task in Synology to do this on every reboot (of the NAS, not Emby), then you shouldn't encounter any problems in the future 1 Link to comment Share on other sites More sharing options...

Ninko 24 Posted October 17, 2021 Share Posted October 17, 2021 Might seem a silly question, but isn't this something that should be fixed within emby? Link to comment Share on other sites More sharing options...

But it is a platform/OS issue not a Emby issue. I guess in theory Emby could script update inotify for you but I don't believe Emby should be modifying system files like this. 1 Link to comment Share on other sites More sharing options...
Ninko 24 Posted October 17, 2021 Share Posted October 17, 2021 Oh right ok, didn't know that. Is this a bug that was introduced in DSM 7.0 or was it always there? Link to comment Share on other sites More sharing options...

No it has always existed in I believe all Linux/MacOS platforms. It is just these standards inotify values are not large enough. Link to comment Share on other sites More sharing options...
Ninko 24 Posted October 17, 2021 Share Posted October 17, 2021 If I was to turn real time monitoring off in emby would that stop the errors in the log? I assume the scheduled task of scanning media library would continue working? Link to comment Share on other sites More sharing options...

It only affects Real Time Monitoring and has no effect on Library scans. But is a easy fix provided above or here. Link to comment Share on other sites More sharing options...

Agreed, Emby shouldn't be run as a user that has access to sudo type commands so it would be difficult to do because of permissions. Only a system admin should be making changes like this to the system, even though it's a trivial change. Link to comment Share on other sites More sharing options...
FrostByte 3481 Posted October 17, 2021 Share Posted October 17, 2021 Maybe this should be in the kb? This seems to come up every week and we're always linking to an old thread for someone to sift through. There are a couple ways to fix it with me preferring to use a bootup task to change both values, but maybe cayars can use one with a little explanation of why/what. 1 Link to comment Share on other sites More sharing options...
cayars 3518 Posted October 17, 2021 Share Posted October 17, 2021 (edited) I have been meaning to add this info to the KB. There seems to be a couple different ways to do this. For example you use the GUI to set this on startup and I tend to use a "sudo" command to make a permanent change. I seem to recall this working slightly different on a couple OSes as well but can't remember specifics right now. It probably wouldn't hurt to start a new thread to ask a few people to try changing this value using specific commands to make sure it sticks on restart to verify commands that work and keep updating the KB as we go. Gotta start somewhere. Edited October 17, 2021 by cayars 1 Link to comment Share on other sites More sharing options...

WHile Emby shouldnt be run as a admin normally, during setup it should be fine to have that level of permissions. I dont see why on install, it couldnt verify the value, and on startup log a message saying the message is too small. Link to comment Share on other sites More sharing options...
cayars 3518 Posted October 18, 2021 Share Posted October 18, 2021 Not possible to do on many OSes. For example part of DSM 7 update forbids this from taking place. That's why the user ends up having to do the migration vs our setup scripts (we tried). Link to comment Share on other sites More sharing options...

Two possible suggestions to easy the issue. 1) In the log, for known issues like this, put a link to the knowledge base page. So if someone is reviewing their log and see an error that concerns them, they can simply click it, and learn how to fix the issue. 2) On the dashboard page, add a "Run a Checkup" button. When clicked, it would analyze the log files looking for known issues. Then list them with their likely solutions (or links to them). Link to comment Share on other sites More sharing options...
