RTM (inotify) doesn't seem to be working on Diskstation 7.1

[Manp82 0]

So, i'm running Emby server on my DS414 on the latest 7.1 update available and everything seems to be working amazingly for the most part.

The issue is basically that real time monitoring on my library folders doesn't seem to be working.

I'm running the latest non beta version of emby server 4.10.1.0 but the same behaviour with real time monitoring was happening on the previous 4.9.5.0.

everything seems to be set up the right way:

- RTM enabled on my libraries

- i have the script running on startup setting increased inotify values:

/sbin/sysctl -w fs.inotify.max_user_watches=1048576
/sbin/sysctl -w fs.inotify.max_user_instances=4096

and checking the values from ssh returns what was set:

root@DiskStation:~# cat /proc/sys/fs/inotify/max_user_instances
4096
root@DiskStation:~# cat /proc/sys/fs/inotify/max_user_watches
1048576

- google suggested running this commad to check which processes are actually using inotify and it doesn't seem that emby is actually using it:

admin@DiskStation:~$ sudo find /proc/*/fd -lname 'anon_inode:inotify' 2>/dev/null | cut -d/ -f3 | xargs -I '{}' ps -p '{}' -o pid,comm                          PID COMMAND
    1 systemd
  PID COMMAND
10947 Plex Media Serv
  PID COMMAND
13053 synoindexscand
  PID COMMAND
15712 session_watcher
  PID COMMAND
 1850 dbus-daemon
  PID COMMAND
 1861 dbus-daemon
  PID COMMAND
 1988 syslog-ng
  PID COMMAND

  PID COMMAND
 2926 synoscheduled
  PID COMMAND
 6164 avahi-daemon
  PID COMMAND
 6888 synocrond
  PID COMMAND
 8137 crond

- logs suggest Emby is watching my media folders:

2026-10-07 16:36:41.396 Info LibraryMonitor: Watching directory with new FileSystemWatcher for /volume1/video/film for item 4
2026-10-07 16:36:48.539 Info LibraryMonitor: Watching directory with new FileSystemWatcher for /volume1/video/serie tv for item 6007

- the emby user have read/write permission on the folders and i'm pretty sure they're set correctly since it can write metadata and .jpg files to every movie folder just fine.

- Plex is able to update its library with no issue as sson as a new file is added.

- with a manual or scheduled library scan Emby picks up the new files with no issues.

 

yet Emby doesn't want to pick new files when added either automatically by radarr or manually by me.

log attached was taken on a fresh start of the emby server after a reboot of the host nas and after coping a new .mkv file to one of the monitored folders.

any help would be greatly appreciated.

Perhaps nevermind... you did mention you had a script running.

Yes, that’s the first thing i checked even tho i have no inotify related errors in the logs.

i had that script running on startup for god knows how long, I don’t even remember why i added it but it was already there when i noticed RTM wasn’t working.

thanks for your reply.
