gogginguy 4 Posted February 24, 2025 Posted February 24, 2025 Occasionally, some (but not all) of my libraries which have had movies added from an external hard-drive cannot be found. (If I try to play one movie, I get "no compatible streams". The only remedy is to restart the Emby server, which necessitates re-scanning. Again, not every library has this problem, just a few -- but if it does affect a library, every movie from the external drive cannot be played. The big headache from this is that movies I've added to a Collection, which get afflicted by this glitch, gets removed and I have to manually add these movies again. I thought that perhaps the drive was entering in a mode (sleep or something), but a couple of facts don't support this: First, I can read from the drive anytime but it doesn't clear up the library's access. Second, only some libraries have this happen (as mentioned above). All movies in all libraries that have movies added from the drive would all be inaccessible, so this is most likely to be something with Emby. I've gone as far as I can go with the non-Emby end of things. Is this a known issue? Thanks in advance, -Wes
Luke 42077 Posted February 25, 2025 Posted February 25, 2025 Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. Thanks!
gogginguy 4 Posted February 25, 2025 Author Posted February 25, 2025 (edited) This isn't a playback issue. This is a "things disappearing from the library" issue. It's impossible to know when this happens exactly as it is something I notice perhaps days later, a may take weeks to appear. This only happens with the external drives. I'd just like to know if this is a known issue. Edited February 25, 2025 by gogginguy

Happy2Play 9780 Posted February 25, 2025 Posted February 25, 2025 Probably need to see server log and maybe even with debug enable for when it happens but does sound like a odd issue as it should affect the entire drive not specific files. But can only be something specific to your setup. 1
gogginguy 4 Posted February 25, 2025 Author Posted February 25, 2025 When I setup the external drive, it could "see" but not navigate into the directories until I changed something with the permissions or something -- I don't remember and I don't have any notes about it (unlike me). Please let me know how best to enable debug. I'll have to fix things manually, and then check it each day until it happens again. Thanks
Happy2Play 9780 Posted February 25, 2025 Posted February 25, 2025 A server log would be the first step when issues happen. Then we may need you to enable debug logging is nothing is seen. But your issue does not make much sense so far.
gogginguy 4 Posted February 25, 2025 Author Posted February 25, 2025 Add to the particulars that a) the linux system restarts on it's own from time-to-time. I will have to see if there's a causation there. b) the server is a docker'd container which does not start upon reboot. I do it manually with each linux restart. Neither should make any difference, but best to note.
gogginguy 4 Posted February 26, 2025 Author Posted February 26, 2025 (edited) It happened again. I restored from the previous day's backup. Perfect. I added all of my 4K movies to a Collection named "4K". It listed 49 in the Collection. Just now, I checked and "4K" only has 46. The three missing movies all come from the same external drive directory /home/4KMOVIES/Drama. What log files would you like to see? Edited February 26, 2025 by gogginguy

So it could be the current embyserver.txt or the previous one.

Happy2Play 9780 Posted February 26, 2025 Posted February 26, 2025 (edited) OT: you need to adjust inotify also. 2025-02-26 01:52:10.925 Error LibraryMonitor: Error creating FileSystemWatcher for: 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. Looks like we only have a how to for Synology from Linux forum. Looks like you need to adjust instances instead of watches. fs.inotify.max_user_watches=1048576; fs.inotify.max_user_instances=4096; Edited February 26, 2025 by Happy2Play
gogginguy 4 Posted February 26, 2025 Author Posted February 26, 2025 I don't know Synology, but will try different settings anyway. To answer: 33 libraries (18 have /storage/4KMOVIES/<library> mapped) The others are not mapped to that external drive.
Happy2Play 9780 Posted February 26, 2025 Posted February 26, 2025 @Lukeor @sa2000may have to help with the validateChildren error on all those libraries then.

This is really nothing to worry about. It just means that the folder was offline or not available during the time of the library scan: 2025-02-26 07:30:57.291 Error App: Error in validateChildren for 33254 /storage/walter/OTHER MOVIES/damaged System.IO.DirectoryNotFoundException: System.IO.DirectoryNotFoundException: Could not find a part of the path '/storage/walter/OTHER MOVIES/damaged'. Whatever the case may be, the server couldn't reach the folder, but the library scan can handle this and keep going and scan other things.
Luke 42077 Posted February 28, 2025 Posted February 28, 2025 Quote The only remedy is to restart the Emby server, which necessitates re-scanning. Why does restarting the server result in re-scanning? Did you set that up?

Who were you talking to when you said it's nothing to worry about? I worry. I worry I have to re-do things. Each time. Why is it going "offline"? I installed inotify and changed these settings: fs.inotify.max_user_watches=1048576 fs.inotify.max_user_instances=4096 Committed them and confirmed: sysctl -p cd /proc/sys/fs/inotify/ cat max_queued_events ;cat max_user_instances ;cat max_user_watches Then rebooted. This morning, I get this: 16:24:31.928 /storage/4KMOVIES/Sci-Fi/2001- A Space Odyssey [imdbid=tt0062622]/Featurettes/2001: The Making of a Myth.mkv: No such file or directory (same with the movie: No such file or directory)

Is it permanent mount ? And is ":" in a filename supported on the filesystem that you have running?

I do it manually with each linux restart There may be docker aspects to how external drives need to be mounted It does not seem to be an Emby issue Initially you had 128 inotify limit which meant you would need to do manual or time scheduled scans to find any added media And all the errors were I/O Errors, eg System.IO.IOException: System.IO.IOException: Input/output error : '/storage/4KMOVIES/Drama/Karate Kid [imdbid=tt0087538]' Edited March 4, 2025 by sa2000
gogginguy 4 Posted March 4, 2025 Author Posted March 4, 2025 "are the permissions being set automatically correct" -- yes, the movies get added and play just fine. "And is ":" in a filename supported on the filesystem" -- yes (and this is happening to more than just this title) "Is it permanent mount" yes -- as much as external storage can be. "I am not a linux expert" then, I'm guessing you know even less about docker. Thanks for playing. 1

gogginguy 4 Posted March 6, 2025 Author Posted March 6, 2025 Nope. I'm restarting the container each morning just to save me the headache until I can get a line on a possible fix.
