TrueNAS Administration Guide#

The complete UNAS-Pro backup architecture, schedules, TrueNAS node configuration, and recovery procedures are documented in Unifi UNAS-Pro Backup Strategy.

1. TrueNAS Scale: Initial Setup & Security#

Virtual Machine Configuration (Proxmox)#

• Initial Setup: Create the VM. Add a second virtual disk (10GB) for apps and home directories.
• Post-Login: Verify the Time Zone is accurate.
• Duplicate Serial Error: If Proxmox reports Disks have duplicate serial numbers, add serials manually in the PVE host:

  nano /etc/pve/qemu-server/212.conf
  # Add serial strings:
  scsi0: Storage:vm-212-disk-0,discard=on,size=32G,ssd=1,serial=PROX-001
  scsi1: Storage:vm-212-disk-1,discard=on,size=1G,ssd=1,serial=PROX-002

Datasets & Users#

1. Datasets: Create HP3-10Gb-Apps-HomeDirs. Add sub-datasets Apps (Type: Apps) and HomeDirs (Type: Generic).
2. Standard User: Create user marc for SMB shares.
3. Sync User: Create backupuser. Set a home directory, uncheck Samba authentication, and do not set a password.
4. Admin Hardening: - Create user marcoue with full admin rights.
   • Upload SSH keys and enable 2FA for marcoue.
   • Disable the default truenas_admin account once verified.

SSH Hardening#

sudo nano /etc/ssh/sshd_config
# Modify/Add:
PermitRootLogin prohibit-password
PubkeyAuthentication yes

sudo systemctl restart sshd

• Services: Go to System > Services > SSH and disable “Allow Password Authentication.”

2. System & Networking Optimization#

Startup Scripts & Cron#

• Cron Shutdown: (System Settings > Advanced)
  • Command: /sbin/shutdown -h now
• Init Scripts: (Post Init)
  • Command: iperf3 -s -d
• Session Timeout: (Access > Configure) Set to 2147482.

Host Identification & Email#

• Hostname/NetBIOS: Set to HP2TrueNAS.
• Gmail OAuth/SMTP: - Use OAuth login if available.
  • SMTP: smtp.gmail.com | Port: 25 or 587.
  • Use an App Password from 1Password.

3. Data Protection & Replication#

Periodic Snapshots (Source)#

• Path: Data Protection > Periodic Snapshot Tasks.
• Settings: Uncheck “Recursive” (unless needed). Uncheck “Taking Empty Snapshot.”
• Schedule: Daily at 08:30, retention 7 days.

Replication Task (Remote Server Pull)#

1. Source: Different System.
2. Connection: New SSH (Semi-Auto).
3. Settings: Admin: marcoue, User: backupuser. Enable passwordless sudo.
4. ZFS Commands: Check “Use Sudo for ZFS Commands.”
5. Schedule: Every hour at 08:45.

4. Syncthing Deployment#

TrueNAS Scale Implementation#

1. System Settings > Advanced > Sysctl:
   • Var: fs.inotify.max_user_watches | Value: 524288.
2. Apps > Advanced: Disable “Host Path Safety Check.”
3. App Setup: Install Enterprise Version. Use Host Path for storage (e.g., /mnt/HP1-4TBSSD-Raid0/HP1Storage).

5. Hardware-Specific Configurations#

Mac Pro Auto-Restart (After Power Outage)#

cd /sys/bus/pci/devices/0000:00:1f.0
sudo chmod -R 777 config
setpci -s 0:1f.0 0xa4.b=0

Wake-on-LAN (WOL) Persistence#

Create a systemd service to ensure WOL stays active:

UniFi Device SSH Configuration#

This guide covers hardening and configuring SSH access for UniFi consoles (UDM-SE, UNVR, UNAS-Pro) and management of secondary devices like Switches and Access Points.

1. Console Configuration (UDM-SE, UNVR, UNAS-Pro)#

SSH Key Setup#

1. Edit the authorized keys file to add your public keys:

nano .ssh/authorized_keys

# Restart the service
systemctl restart sshd

Install Tailscale#

For complete subnet advertising (10.1.0.0/16), exit node setup, and route approval guidelines, see the Tailscale Guide.

UPS Tools (Network UPS Tools) Setup Guide#

This guide covers the installation of a NUT Server on a central VM (230) and the configuration of NUT Clients (Proxmox nodes) to ensure graceful shutdowns across your infrastructure.

1. NUT Server Installation (VM 230)#

1.1. Prerequisites & Software#

# Verify USB visibility (Ensure USB passthrough is configured in Proxmox)
lsusb

# Install NUT suite
apt update && apt install nut nut-client nut-server -y

1.2. Ubuntu 24.04 (NUT 2.8.1) Library Fix#

If USB scanning fails on Ubuntu 24.04, create the following symlinks:

Wake-on-LAN (WOL) Configuration & Inventory#

This guide covers how to enable, persist, and verify Wake-on-LAN (WOL) across Linux nodes and Proxmox hosts, followed by a comprehensive MAC address inventory for the local and remote clusters.

1. Verification & Manual Activation#

Check WOL Support#

Use ethtool to check if your network interface supports the “Magic Packet” (designated by the letter g).

# Replace eno5 with your actual interface name
ethtool eno5 | grep Wake-on
