I have an issue that has been going on for roughly 3 months now of the 10 months my server has been running on my Synology DS1019+. I noticed movies were slowly disappearing from my plex library, once I ran webtools I found a ton of movies missing from plex, and was able to do the plex dance, or in most cases simply move them out of the library folder to a folder not seen by plex and then back in, where a scan would trigger and they would reappear.
Most of the missing movies seem to disappear from plex after they have been updated to a higher quality version by radarr, but in some cases new movies simply dont show up in plex, even after forcing a manual scan. The most recent movie to receive an update from radarr and disappear from plex is Captain American: Winter Soldier, probably visible in the logs.
Permissions, on Synology, are very delicate. This is because Radarr and Sonarr only understand Linux permissions but Synology is ACL based.
On Synology, best permissions are either:
a. Assign no permissions in Radarr/Sonarr and let Control Panel - Shared Folders - Permissions tab handle it
b. Assign 755 for directories and 644 for files.
Thanks, my radarr media naming was the same except for “clean title,” I was using “title.” My sonarr naming was still default with file quality included. I changed it to match, but had not checked it prior because I have experienced none of my current woes with TV files.
As far as permissions, plex has read only access for both data folders on 2 different volumes per the shared folder manager in DSM.
This way, when I realize I’ve manually named a bunch of manual imported discs incorrectly, I can rename all of them in one shot. IMHO, part of the standard toolkit for when curating media.
Reset my permissions according to this guide, I will see if that helps.
I do not use filebot, I rely on radarr/sonarr for all renaming, which has worked flawlessly until I started running into these issues recently.
I just added 6 movies to my collection via radarr, upon completion only 5 were detected by Plex. I ran a manual scan which did not find the missing movie, I had to remove it from the target directory and place it back in before plex detected it.
Yes I’m sure, if I have been away from my setup for a few days I run webtools and it shows me (in my case) the list of movies that once existed in plex, were upgraded by radarr and no longer show up in plex. The plex dance fixes the issue, a manual scan does not.
Issue is still occuring, last night an old movie I had in plex was upgraded to a higher quality by radarr, today it was simply missing from plex, but present in the media folder.
If I were to wipe PMS off my Synology, leaving the media folders and then reinstall PMS, what all would I lose? Just play history? I don’t know what else I can try. Radarr is behaving correctly, the media is where it needs to be, and is labeled correctly, permissions reset.
I figured out the issue. Plex has permissions as appropriate for the shared folder, radarr creates a folder for each movie, which it grants plex access to, BUT once the movie is renamed and moved into that folder, it does not grant plex permission to view the specific file. If I take the movie folder out of the shared folder and place it back in it resets the permissions all the way down to the file level, including adding plex permissions.
I believe the fix resides somewhere in radarr “set permissions,” ill have to dig a bit further.
EDIT For those that may find this post in the future, the issue resides within the setup of docker containers for radarr/sonarr, somewhere along the line my setup went sideways a bit probably regarding puid/pgid etc, the bandaid fix is to have radarr assign permissions 777, but it certainly does not treat the underlying issue.
