When you say “automount”, are you referring to a configuration within /etc/fstab, or are you referring to the automounter facility, generally configured in /etc/auto\* ? I’m hard mounting an NFS share from a Synology device on CentOS 7 without issue. Your description of the problem leads me to suspect that you’re trying to use the automounter facility, and I’m not sure that’s going to work well, PMS expects the share to always be mounted. AutoFS does have it’s share of issues as well. Edit: pay close attention to @ChuckPA’s response. ---

On Synology: 1. Create a user named `plex`, in group `users` (the default group) 2. This username is used by NFS and the Synology tools to allow permission to specific shares. 3. Control Panel - File Services - Enable NFS service. ![Screenshot from 2020-06-23 15-53-31](https://global.discourse-cdn.com/plex/original/3X/9/2/92b9506b2aa78be767c7b32ccb7ffee8f66bfc3e.png) 4. Control Panel - Shared Folders : Grant permission to those shares you want user `plex` to have access over the LAN. 5. The Synology is now ready. Return to Linux, 1. Make certain your username owns the mount point directories. 2. Also make certain the mount point directories have permissions 755. 3.

absolutely. You need not use all the customizations I show in this How-To. You will need to change the ownership of `/var/lib/plexmediaserver` (as it shows) to match your new username. > [@Customizing your Plex configuration](https://forums.plex.tv/t/customizing-your-plex-configuration/205443): > > Customizing your Plex configuration on systemd based systems This information is intended for those systems where cat /proc/1/comm returns systemd.
