Recently I have upgraded my good old Synology DS411slim to newer, bigger model - DS918+. I kinda started to run out of free space (1TB 2.5” x4) and decided to invest some money into new box and new drives.

There is an official guide how you can do migration with disk swipe, but as I wanted to move my data to new drives I just decided I would try to rsync everything. And BTW there is a screen command if you would like to run in the background that can be found on synocommunity.

Long story short I had poor experience with rsync - tweaking settings on both end (disabling compression, tinkering with used crypo algo and so on) yielded rather disappointing results - transfer up to 10MB/s and almost 100% CPU utilization on my old NAS.

Weirdly enough I had much better luck with simply mounting CIFS resources in my new nas from my old nas directly in DistStation File Manager (Tools -> Mount Remote Folder -> CIFS shared folder). That doubled transfer speed and lowered CPU usage ~2x times. So far so good.

Aside from standard packages like PhotoStation (and btw if you move your photos directory it should just work) I also had SickChill (previously SickRage and before that SickBeard as apparently there was some fight over the project) and transmission that I wanted to move.

My goto solution were packages from synocommunity, but I noticed my new box have great support for Docker - Synology provides official Docker package. So I decided to give it a try.

New stack

After some research I ended up with Medusa (as replacement for SickChill), Radarr (for managing movies collection), Jackett (that acts as proxy between medusa and radarr and various private torrent trackers) and rutorrent (as replacement for transmission as radarr don’t have unpack rar archives capabilities).

Hopefully for me there is a linuxserver community that released all the images that I needed, so basically half the work as done. Opensource ftw 💪.

I’m using three virtual volumes on my synology:

Sample docker compose will look something like this:

---
version: "2"
services:
  radarr:
    image: linuxserver/radarr
    container_name: radarr
    environment:
      - PUID=1024
      - PGID=100
      - TZ=Europe/Warsaw # or whatever your timezone is
    volumes:
      - /volume1/docker/radarr:/config
      - /volume3/video/movies:/movies
      - /volume2/torrent:/downloads
    ports:
      - 7878:7878
    links:
      - jackett
      - rutorrent
    mem_limit: 1g
    restart: unless-stopped
  jackett:
    image: linuxserver/jackett
    container_name: jackett
    environment:
      - PUID=1024
      - PGID=100
      - TZ=Europe/Warsaw
    volumes:
      - /volume1/docker/jackett:/config
    ports:
      - 9117:9117
    mem_limit: 512mb
    restart: unless-stopped
  rutorrent:
    image: linuxserver/rutorrent
    container_name: rutorrent
    environment:
      - PUID=1024
      - PGID=100
    volumes:
      - /volume1/docker/rutorrent:/config
      - /volume2/torrent:/downloads
    ports:
      - 9091:80 # so you can access rutorrent on port 9091 on your synology
      - 5050:5000
      - 51413:51413
      - 6881:6881/udp
    mem_limit: 512mb
    restart: unless-stopped
  medusa:
    image: linuxserver/medusa
    container_name: medusa
    links:
      - jackett
      - rutorrent
    environment:
      - PUID=1024
      - PGID=100
      - TZ=Europe/Warsaw
    volumes:
      - /volume1/docker/medusa:/config
      - /volume2/torrent:/downloads
      - /volume3/video/tv:/tv
    ports:
      - 8081:8081
    mem_limit: 1g
    restart: unless-stopped
