Server Version#: 1.21.3.4021
Player Version#: Web 4.51.1
It appears that in the last ~1 week my Plex server has lost the ability to automatic scan folder as I change them.
The largest thing that I did recently was migrate Volumes on Synology. I added Volume 2 and made it my main volume. To move the App install locations, I followed the instructions here: https://veducate.co.uk/synology-moving-a-package-between-volumes/
So Plex now lives on Volume 2 with all apps, and the media is on that same volume in its own folder. Around this time, (though I am not sure if immediately following) it appears that PMS server lost the ability to automatic scan. Manual scanning works fine and it is able to record/add manually/do pretty much everything else ok.
I was thinking maybe a whole refresh of PMS would fix the issue, so I deleted the entire Plex Share/user/everything from plex and reinstalled again on Volume 2, but the same result after letting it rebuild libraries overnight. I find this particularly annoying as a I have a separate script that runs on another computer and converts automatically with handbrake the recorded media from MPEG to MKV.
I was not able to find anything on the forums about PMS having an error with automatic scanning on the most recent versions so it leads me to believe it was something that I did.
Has anyone run into a similar synology issue before, and if so what did you do to solve?
Good point, I had seen that number crop up before but forgot to look before posting.
I did test and it appears I am under the limit:
I should do some cleanup there anyways as I donāt think I should have that many folders, but I donāt think itās hitting that 8192 directory limit yet.
Synology is normally displayed on a white background and a text-based āfind | wcā command doesnāt print in such verbose text. That also looks like a windows āDirā command ?
Correct, that was using a dir /w /s command from a windows computer that has access to the media folder.
I just ran, the find | wc command on the same folder just through SSH on the Synology box and it showed a different result:
I also just checked the Synology properties itself and it only shows 1770 folder for the same media folder.
Looking in the Plex share ā not appropriate unless you put media there (which you shouldnāt do) ā but if you did, add the specific media-containing folders to the list below.
letās now qualify that find command and get an accurate result since youāre ok with using the SSH command line (some arenāt)
If you use /volume1/media and /volume2/media for all your media files,
then
find /volume1/media /volume2/media -type d -print | wc -l
You can add as many directories as you want before the -type command.
Use that number and follow the rest of the procedure as Iāve shown in the How-To
Got it, I think I misled you in my previous answer. Wasnāt using the Plex share for media storage, just a separate shared folder where all media is (in two folders: Movies, TV Shows) that is an SMB share that windows can see.
In any case, I ran the find command as you showed above through SSH on that same top level folder where all media is stored and got the result of 7576. This was higher than I expected, so I went through some folders and did a little tidying and ended up with 7314.
I am still not 100% sure that the folder limit is the problem here, but I will do the how-to in any case since clearly I will be nearing that limit soon.
One thing that will trip you up (it did me until I beat the heck out of it and proved it)ā¦
Server (share) side network share changes are not reflected through the notify.
On Linux, if the local file system changes, the kernel sees it and reacts.
However, if those changes are made on a remote host, independent of THIS kernel, it will not know it changed.
Is everything on the Synology or is there data elsewhere off-Syno?
Regarding those two directories you show.
7576 + 7314 = 14890 which is greater than 8192.
Am i reading this correct? You have Plex indexing media in both shared folders?
If I am correct, then I suggest you set the user_watches to 32768 to allow room for growth. 32K worth of notify slots = a little over 16 MB. The default is 4 MB of memory so itās not a big increase.
So I believe any changes I make to these two folders via Windows through SMB will be reflected on the Synology filesystem and therefore plex (and indeed this is how Iāve had the media conversion script working since like 2018).
Regarding those two numbers I sent, they were both on the same XXXXXX-Media folder that I sent here, so are not added. (Sorry for being confusing) I ran the find command once before and once after deleting some empty folders with the the -Media subfolders. So the result of the find command on the XXXXXX-Media folder and all subfolders is 7314.
I am going to try the How-To now in any case and will report back.
EDIT:
Tried the increase, rebooted synology and moved some items around. No change.
I did want to add that this new volume is btrfs whereas the old one that I moved the files from ext4. Based on a quick google that shouldnāt cause any problems for plex.
Updated today to Version 1.21.3.4046.
Afterwards, I added a new piece of media and Plex was able to recognize, scan and add the media to the library. Good news!
However, I attempted to move an episode of a show out of the scanned media folders, and that did not trigger an automatic scan which is something that it used to do.
I did make sure that automatically empty trash after each scan was enabled, but it just seems like files being removed is not triggering a scan.
Iām not sure I understand what you mean.
It seems to react in that when I click on the tv episode/movie it is listed as āunavailableā and will not play, but the normal action of removing it from the library does not appear to happen. If I put the file back, plex is again perfectly happy.
However, after some additional testing, Iāve noticed that this is only happening for certain media. Some shows if I delete an episode, plex sees this, partial scans folder, and empties trash. Not for others though.
Thank you both again for you help so far. @trumpy81 I followed your steps as listed above (twice actually for fear I did it wrong the first time).
However, I am still seeing the sort of half removal I talked about before.
For example:
The Great North, a Fox broadcast show I recorded from Plex DVR (and subsequently converted to MKV).
If we look in the Synology File Station, I have moved S01E03 away someplace else that Plex canāt see.
From past experience, if I were to scan the library manually this would remove itself, but itās been ~45 minutes since I removed it and it still shows in this state after several plex player refreshes.
PMS will get confused because Synology uses them interchangably .
Best results is to go into Settings - Server - Network - Show Advanced
Select which adapter (192.168.1.168, or 192.168.1.169) you want as the Preferred adapter for PMS
Next:
Permission denied errors . User Plex doesnāt have access to the media. Specifically looks like Synology dropped permission for user Plex on the /volume2/Reekris-Media shared folder. (it does this often in DSM 6)

Once that happens , there is a bunch of secondary errors. I suggest taking care of this first.
So just for fun, I created an additional test Share Folder from scratch on Volume2.
Owned by the account I use, and Plex RW permissions.
Made a folder called Shows2, dumped a few shows in there, and added it to the TV library in Plex.
Works perfectly. Anything I add/move/delete is instantly recognized and treated appropriately including emptying trash.
EDIT: I suppose barring anything else its not the end of the world to make āTest-Mediaā the new plex folder and just fire the old one into the sun.
