Proxmox LXC Storage Mounts#

What Was Established#

• SMB/CIFS shares can be integrated into Proxmox via CLI or the Web GUI.
• GUI integration is recommended for Proxmox-native features (backups, ISOs, templates) and automatic retention management.
• LXC containers can directly mount Proxmox storage paths using mp0/mp1 directives in the container config file.
• Separate CIFS storages should be used for media vs. backups to maintain clean separation of concerns.

Key Decisions#

• Storage Content Types: For media-only CIFS shares, select Container templates, ISO images, or Disk image. Explicitly avoid Containers and VZDump backup file to prevent Proxmox from treating the media share as a system storage.
• Subdirectory Configuration: Leave the Proxmox storage subdirectory field blank to mount the root of the SMB share, enabling flexible navigation to specific subfolders (e.g., Documents/Movies).
• Jellyfin Path Targeting: Point Jellyfin directly to the specific media subfolder (e.g., /media/synology/Documents/Movies) rather than the mount root.

Current Configuration#

• LXC Config Path: /etc/pve/lxc/<CT-ID>.conf (e.g., /etc/pve/lxc/100.conf).
• Mount Syntax: mp0: /mnt/pve/<Storage-ID>,mp=/media/<mount-name>
• Permission Mapping (for unprivileged containers):

  lxc.idmap: u 0 100000 65536
  lxc.idmap: g 0 100000 65536
  lxc.idmap: u 1000 1000 1
  lxc.idmap: g 1000 1000 1
  lxc.idmap: u 1001 101001 64535
  lxc.idmap: g 1001 101001 64535

• Jellyfin Setup: Dashboard → Libraries → Add Media Library → Folders: /media/synology/Documents/Movies.

Historical Notes#

• Conversation date: 2025-11-07.
• Focuses on resolving LXC mount visibility and permission issues for Jellyfin on a Synology NAS.
• No major infrastructure changes flagged; patterns remain valid for Proxmox 8.x.

Open Questions#

• None.
