External drive not visible in Plex

[Draculya]

Hi,

I have a RPi 5 and added an external drive which has the files that I want to add to Plex, but when I try to create a library, I can’t navigate to it or force plex to see it.
I mapped as a drive in Windows without any issue and I’m able to access the drive in Linux, but Plex can’t.

Any thoughts?

Thx in advance,

Hi,

Thx for the reply but the drive is connected to the Raspberry Pi 5 via usb and mounted under media/user/“drive label” but plex is unable to see the files in it.
If I use my Windows machine which also has PMS, it can via the smb share,

The drive is fornatted as exFat.

I understand and that’s all superficial / immaterial.

as I posted.

For your case, where I show /run/media, you have /media (this is a Redhat / Debian difference with the automounter)

H again,

Thx for the help
It worked perfectly

Hi,

Sorry to bother again but after PMS been able to access the drive, I can’t make any changes to it remotely or within the Raspberry PI OS/Debian 12.

The owner of the folder /mnt/xxxxx is root and even changing chmod to all users, after mounting again the folders of the drive are set to the user root and I can’t change their permissions

[ChuckPa]

A few things:

1. Always make certain of the permissions of the mount point directory BEFORE the drive is mounted.

2. exFAT and NTFS, being Microsoft filesystems, don’t show up in Linux as you expect.
   – They have no sense of ownership and always owned by root (the system)
   – They have no sense of ‘chmod’ permission bits. They use Microsoft ACLs - which Linux doesn’t support

Now you need to change how the drive is mounted and emulate what Microsoft is doing.

Here’s the How-To.

Ownership/permission problem with automounting exfat drive

What’s important to remember,

1. You want your UID to own the media
2. You want Plex’s GID to be the assigned group so it can read the media.
