Mount Storage into LXC & VM#

The Plex LXC gets the storage via a direct bind mount. The Docker VM gets it via NFS. Both end up with the same paths: /mnt/media/movies, /mnt/media/tv, and /mnt/media/downloads.

Plex LXC — bind mount#

Bind mounts in LXC containers are configured in the LXC config file on the Proxmox host.

Find the config file at /etc/pve/lxc/<id>.conf (replace <id> with your LXC ID, e.g. 103).

Add these lines:

mp0: /tank/media/movies,mp=/mnt/media/movies
mp1: /tank/media/tv,mp=/mnt/media/tv
mp2: /tank/media/downloads,mp=/mnt/media/downloads

Restart the LXC:

pct stop 103 && pct start 103

Verify inside the LXC:

ls /mnt/media/movies
ls /mnt/media/tv

Docker VM — NFS#

1. Set up NFS on the Proxmox host#

Install NFS server:

apt install -y nfs-kernel-server

Add exports to /etc/exports:

/tank/media  192.168.1.0/24(rw,sync,no_subtree_check,no_root_squash)

Replace 192.168.1.0/24 with your LAN subnet. Apply the export:

exportfs -ra
systemctl enable --now nfs-server

2. Mount NFS inside the Docker VM#

Inside the Docker VM, install the NFS client and create mount points:

apt install -y nfs-common
mkdir -p /mnt/media/movies /mnt/media/tv /mnt/media/downloads

Add to /etc/fstab (replace 192.168.1.50 with the Proxmox host IP):

192.168.1.50:/tank/media/movies    /mnt/media/movies    nfs  defaults  0  0
192.168.1.50:/tank/media/tv        /mnt/media/tv        nfs  defaults  0  0
192.168.1.50:/tank/media/downloads /mnt/media/downloads nfs  defaults  0  0

Mount everything:

mount -a

Verify:

df -h | grep mnt

Result#

Both the Plex LXC and the Docker VM now see the same paths:

/mnt/media/movies
/mnt/media/tv
/mnt/media/downloads

This shared path structure is what allows Sonarr and Radarr to hard-link files from downloads into the final library without copying.
