Synology Administration Guide#

1 Syncthing Deployment#

1.1 Synology DSM Implementation (Docker)#

1. Inotify Limit:

   echo "fs.inotify.max_user_watches=204800" | sudo tee -a /etc/sysctl.d/90-override.conf
   sudo sysctl -p /etc/sysctl.d/90-override.conf

2. User IDs: Use Task Scheduler to run id > /volume1/docker/id.txt to find UID/GID (e.g., 1027/100).
3. Docker Compose Highlights:

   environment:
     - PUID=1027
     - PGID=100
     - TZ=America/New_York
   volumes:
     - ./config:/config
     - /volume2/HP3Storage:/volume2/HP3Storage

1.2 Standard .stignore Patterns#

Create a .stignore file in the root of the sync folder:

(?i)#recycle
@eaDir
.DS_Store
.stfolder
.stignore
$RECYCLE.BIN
Thumbs.db
Desktop.ini
.SynologyWorkingDirectory

2 Storage & Maintenance Commands#

2.1 iPerf3#

sudo -i
synogear install
iperf3 -s -p 11111

2.2 Locked Folder Cleanup#

Remove Synology metadata directories when cleaning up a locked folder:

Immich & Photo Management Guide#

1. Synology Photo Workflow#

Album Creation#

1. In Synology Photo:
   • Move images from Personal space to Shared Space.
   • Create an album with the moved images.

2. Immich Management#

External Libraries & Albums#

1. Scan Libraries: Settings > Administration > External Library > Scan All Libraries.
2. Monitor Progress: Jobs > Check when the job is finished.
3. Create Album: Main page > Albums > Create Album > Select Photos.
4. Sharing: Share with Nadine.

Backup Strategy#

• MacStudio: Use Carbon Copy Cloner to sync HP1 Photos to UNAS.
• UNAS: Backup the Immich folder from UNAS to HP1, HP7, and HP11.

3. Cloudflare Zero Trust: Mobile App Bypass#

Setup Cloudflare bypass access to allow the Immich mobile app to connect without manual Google Auth browser prompts. Reference: Cloudflare Tunnel Guide

Syncthing Installation & Configuration Guide#

1. #truenas TrueNAS Scale Installation#

Increase Inotify Limit#

For real-time file watching on large datasets, increase the inotify limit in the TrueNAS backend.

1. Go to System Settings > Advanced > Sysctl.
2. Add New Sysctl:
   • Variable: fs.inotify.max_user_watches
   • Value: 524288
   • Description: Increase inotify limit for Syncthing.
3. Verify persistence via Shell:

cat /proc/sys/fs/inotify/max_user_watches

App Deployment#

1. Apps > Settings > Advanced: Disable “Host Path Safety Check” (if using existing datasets).
2. Catalog: Search for and install the Syncthing Enterprise version.
3. Storage Configuration:
   • Type: Host Path
   • Host Path: /mnt/HP1-4TBSSD-Raid0/HP1Storage (or your specific data path).
   • Mount Path: HP1Storage
4. Access: Open the Web UI at http://[IP]:31000. Set an Admin password immediately.

2. Synology DSM Installation (via Docker)#

Increase Inotify Limit#

1. Connect via SSH and run:

echo "fs.inotify.max_user_watches=204800" | sudo tee -a /etc/sysctl.d/90-override.conf
echo 204800 | sudo tee /proc/sys/fs/inotify/max_user_watches

Identify User IDs (PUID/PGID)#

To avoid permission issues, run the container as your specific user.
