Very subtle points is all you forgot:
- set the base permissions on the directories themselves, before you mount up the media.
- probably forgot to extend read-only permission into your media.
Contrary to the information provided from that other web site, Plex only needs READ permission.
It needs Read-Write if you’re going to use DVR/LiveTV and have it record directly into your main media storage. Most of us keep DVR separate since it’s largely transient. We move it manually if we really want to keep it
This having been said,
two steps:
sudo find /plexmnt -type d -exec chmod 755 {} \;
sudo find /plexmnt -type f -exec chmod 644 {} \;
This allows you to retain permission and full R/W as the Owner but grants Read-only permission to the diretories and files in /plexmnt
Now give it a spin
