New movies not automatically added

General Discussions
1

New movies are not shown when I add to movie folder.
I had to manaully scan all library and wait long time in order have it appear

In the past when I added a file the scan started automatically and in few second I could see the file.
No setting changed, see attached

On what platform is that Plex Media Server of yours?
Linux based system (e.g. most NAS devices) have an OS configuration on how many folders can be monitored. If I remember correctly, the default in somewhere around 80k folders.
If you have a large library you can end up beyond that threshold.

If that applies to your setup you can update the related settings for your OS.

Thanks for reply, I have installed the server on a Win10 PC, the media files are on two external 4 Tb NAS HDD
I have 4202 movies and some TV series
Problem still persit, I added couple of movies yesterday and I could not see them until I performed a full scan

From what I remember automatic library scans don’t work on network drives.

I see, it is also stated: Note : In most cases, this should work for content on local filesystems. It will generally not work for network shares mounted via SMB, NFS, AFP, or similar.

Most of the cases! I have to figure out what has happened as before my vacation everything was working fine, probably a sofware update on my NAS. Thanks a lot!

SMB/CIFS supports directory change notifications, and Windows servers support directory change notifications really well.

Samba also supports directory change notifications, but … it’s not uncommon for smaller NAS appliances to have issues with it. And cross-platform … weirdness. Sometimes they won’t notify when there’s a change within a subdirectory, for instance. Or will notify if the change came from the same client, but not if it came from elsewhere. Etc.

Have you recently added a bunch of media? You mentioned 4000+ items.

“Have you recently added a bunch of media? You mentioned 4000+ items.”

Not really, 4000 media have been added in the last 2 years since I started using Plex.
Now I add 2-3 media a week, when new movies are available…

Random brainfart:
if the SMB directory change check of SAMBA (which is the software that all those Linux-based NAS devices are using to offer Windows-compatible network shares) is relying on Linux inotify events, you may still have to check if you’ve exceeded the default folder count on your machine for inotify: Increase the number of directories Linux can monitor (Notify)

That’s clever, @OttoKerner.

I looked to confirm. Samba checks for inotify.h on Linux, and uses it when “kernel change notify = yes”.

@giabett, does your NAS give you the option to modify sysctls or tunables, as per @tom80H’s first link? Or to add a startup script? Or get to a CLI prompt?

Here is a HowTo for Synology NAS’s Synology FAQ - Questions, Answers, and a few How-To's

That’s very … Synology … of them.

ChuckPA has instructions for QNAP too.

Can I be of any help?

Thanks, for me the situation is quite clear, it is a NAS problem related to the file numbesr, so nothing to do with Plex. I will figure out how to solve the problem.

14

It’s the number of folders, not the number of files.

Well, I wrote a scipt, that can run on linux based share server (eg. a QNAP NAS) to catch new files added, and makes an HTTP call for PLEX to force scan on that folder.

    sleep 1
    else
    url="http://"$PlexIP":32400/library/sections/"$PlexFolderKey"/refresh?path="$path"&X-Plex-Token="$PlexToken
    prev_path=$path
    curl $url
    fi

sleep 1

done

Save this code to an “anything.sh” file, and run it.
It helps for me :slight_smile:
