TV (TV Shows)
Movies (Movies)
Music (Music)
Podcasts (Music)
and the latter two music libraries will not update when files are added. I have to manually refresh the library.
Pretty straightforward repro for this problem: if I watch the log (Plex Media Server.log) and open a terminal and create a file in the TV directory:
> cd /volume1/Plex/TV > touch foo
the server log immediately shows
Library section 2 (TV Shows) will be updated because of a change in /volume1/Plex/TV
and same result for the Movie library. However if I run this test on the music libraries . . . nothing. And of course nothing if I actually add mp3 files to those directories.
Any ideas? This is super-frustrating. I don’t see anything else interesting in the logs.
If the total number of directories monitored by PMS exceeds the Linux default maximum of 8192, PMS will not be able to monitor directories encountered beyond that point without tuning the kernel slightly.
You need to count the total number of directories currently in use. Either use FileStation or do it at the shell.
Then , once you have the total and if over 8192, this procedure applies to you:
You will need to enable SSH access to the Synology and the 3 commands, adjusted to your system of course, as I show in the Example above
Once complete, Restart PMS
