Syncthing

Setup

Syncthing as TrueNAS App

In TrueNAS

• Create syncthing dataset, type Generic (not samba!)
  • Owner probably needs to be 1000:1000
• Add app
  • UID GID 1000
  • Config storage > Host path > choose created dataset
  • E.g. 4 CPUs, 8196 MB

Syncthing as Docker container

Stack config: https://github.com/one137/dockerhost-stacks/blob/main/stacks/40-syncthing.yml

Stream ports 22000 tcp/udp in NPM and add NPM to the syncthing default network.

Post install

In Syncthing UI

• Actions, Settings:
  • Set device name: truenas-st
  • Set GUI auth
  • Edit Folder Defaults:
    • Folder Path: ~/data
    • Ignore Patterns: // #include .stglobalignore
    • Advanced: Folder Type: Receive Only
• Add Remote Device
  • Choose e.g. IZD4XXX
  • Sharing: Auto-accept
  • Accept new device (truenas-st) from other device (IZD4XXX) and check folders to sync
  • Once syncs finished, uncomment line in “ignore patterns”

For a secondary LAN syncthing instance behind a docker bridge, consider disabling Settings > Connections > traversal/discovery/relaying and specifying its address (IP of the host :22000) in the primary instance.
