Permissions issues with Plex in Docker on Synology NAS

Server Version#: 1.21.1.3830

ok, almost at my wits end and the wife is getting frustrated. I recently did a fresh install of Plex using the official Plex docker image. I’m on a Synology RS1619xs+. Currently almost everything seems to be working without issue with one exception. I do not seem to have the ability to either delete media (the option to allow deletions is checked in PMS), or record Live TV. At this point I have made the assumption it has to do with permissions I have not setup correctly. I do have a Plex user account created which I have set the PGID and PUID in the environment and believe I have verified the user has read/write permissions to the root plex folder within docker (and inherited permissions beneath that). Yet I still can’t seem to get these to items to work. Logs are attached for review. (I’m not the best at reading these logs and didn’t see anything related to permissions, but I might just be missing it). I have read other threads which are similar to my issue, but non of those have seemed to pan out for me. Any and all assistance in solving my issues is greatly appreciated (especially by my wife).

thanks!

So as an update I tried this:

Automating Linux permissions using inheritance (Helps DVR) - Plex Media Server / Desktops & Laptops - Plex Forum

That unfortunately did not seem to help. @ChuckPa, I can imagine you are probably slammed, but if you have a moment to assist with this since you are the individual who comes up in all my searches for this problem, I would greatly appreciate your assistance.

Docker , on Synology, is a pain.

You don’t have access to the UID/GID (which you need) to make it work.
You don’t have HW transcoding without hand crafting udev rules.

DSM 7 is going to be worse from what I know now of the native app.

Looking to your best interests, can I get you to reconsider?
Native has HW transcoding
Native will auto migrate to DSM 7 at installation.
plus a few other nice things I’ve added since the DSM 6 days

you know what, based on your expert opinion, I would actually be happy to switch back. Can I simply re-install and move the database files over?

If you recreate the same structure the DSM 6 installer does,

And make certain user plex is the owner of all the files in the Library/Application Support/Plex Media Server path (including subdirs and files),

It will be fine.

The DSM 6 package installer will set the shared folder ACLs.

To give a head’s up to DSM 7, I only ask:

  1. Don’t play with the UID/GID (plex:users)
  2. Don’t hard set Linux permissions as it terminates the ACLs.

Obeying these two conditions will make transition to DSM 7 require ONE step (which it will prompt you for)
