Mount the Synology NFS share to your LXC

Summary: Mount Synology NFS → Proxmox Host → Bind to LXC

Phase 1: NFS Setup on Synology DSM 7

1. Enable NFS Service
   • Control Panel → File Services → NFS tab
   • Check "Enable NFS service"
   • Set Maximum NFS protocol: NFSv4
   • Click Apply
2. Configure NFS Permissions for Obsidian Share
   • Control Panel → Shared Folder → Obsidian → Edit
   • Go to NFS Permissions tab → Create
   • Server or IP address: 192.168.1.24 (or use 192.168.1.0/24 for subnet)
   • Privilege: Read/Write
   • Squash: Map all users to admin
   • Security: sys
   • Check: Enable asynchronous
   • Check: Allow connections from non-privileged ports
   • Check: Allow users to access mounted subfolders
   • Note the Mount Path: 192.168.1.40:/volume1/Obsidian

Phase 2: Mount NFS on Proxmox Host

On Proxmox host (192.168.1.5):

# 1. Install NFS client tools
apt update
apt install nfs-common -y

# 2. Create mount point
mkdir -p /mnt/synology-obsidian

# 3. Mount NFS share (using NFSv3 for compatibility)
mount -t nfs -o vers=3,rw 192.168.1.40:/volume1/Obsidian /mnt/synology-obsidian

# 4. Verify mount
ls -la /mnt/synology-obsidian
ls -la /mnt/synology-obsidian/Notes

# 5. Make mount persistent (survive reboots)
echo "192.168.1.40:/volume1/Obsidian /mnt/synology-obsidian nfs vers=3,rw,relatime 0 0" >> /etc/fstab

Phase 3: Bind Mount to Unprivileged LXC

On Proxmox host:

# 1. Stop the LXC
pct stop 10300

# 2. Add bind mount to LXC config
echo "mp0: /mnt/synology-obsidian,mp=/obsidian" >> /etc/pve/lxc/10300.conf

# 3. Start LXC
pct start 10300

# 4. Verify inside LXC
pct enter 10300
ls -la /obsidian
ls -la /obsidian/Notes
exit

Phase 4: Configure n8n File Access

Inside n8n LXC (10300):

# Edit n8n service file
nano /etc/systemd/system/n8n.service

# Add this line in the [Service] section:
Environment=N8N_RESTRICT_FILE_ACCESS_TO=/obsidian;/root/.n8n-files

# Save and restart
systemctl daemon-reload
systemctl restart n8n
systemctl status n8n

Key Details for Your Setup

• Synology IP: 192.168.1.40
• Synology Share: /volume1/Obsidian
• NFS Export Path: 192.168.1.40:/volume1/Obsidian
• Proxmox Host Mount: /mnt/synology-obsidian
• LXC ID: 10300
• LXC IP: 192.168.1.24
• LXC Mount Point: /obsidian
• Vault Path in LXC: /obsidian/Notes
• NFS Version Used: NFSv3 (vers=3)

Verification Commands

# On Proxmox host - check NFS mount
mount | grep synology
ls -la /mnt/synology-obsidian/Notes

# View LXC config 10300- n8n on proxmox
cat /etc/pve/lxc/10300.conf | grep mp0

# Inside LXC - check mount
pct enter 10300
ls -la /obsidian/Notes
df -h | grep obsidian

This setup keeps your Google Drive as primary, syncs hourly to Synology via Cloud Sync (bidirectional), and makes the files accessible to n8n via NFS.
