Mounting Calypso NAS on Concord NUC

This guide covers mounting the Calypso NAS media share on the NUC for Plex access.

Prerequisites

  1. Verify Tailscale connectivity:

    ping 100.103.48.78  # Calypso's Tailscale IP
    
  2. Install CIFS utilities:

    sudo apt install cifs-utils -y
    

Setup

1. Create Mount Point

sudo mkdir -p /mnt/nas

2. Create Credentials File (Secure)

sudo nano /root/.smbcredentials

Add:

username=Vish
password=REDACTED_PASSWORD

Secure the file:

sudo chmod 600 /root/.smbcredentials

3. Add to /etc/fstab (Persistent Mount)

sudo nano /etc/fstab

Add this line:

//100.103.48.78/data/media /mnt/nas cifs credentials=/root/.smbcredentials,vers=3.0,uid=1000,gid=1000,file_mode=0755,dir_mode=0755,_netdev,x-systemd.automount 0 0

4. Mount

sudo mount -a

5. Verify

ls -la /mnt/nas
# Should show: movies, tv, music, etc.

Troubleshooting

Mount fails on boot

The _netdev and x-systemd.automount options ensure the mount waits for network. If issues persist, check that Tailscale starts before mount:

sudo systemctl status tailscaled

Permission issues

Ensure uid=1000,gid=1000 matches the user running Plex/Docker.

Slow performance

See Network Performance Tuning for SMB optimization.

Performance Notes

  • SMB over Tailscale: ~139 MB/s (1.1 Gbps) - sufficient for 4K streaming
  • Direct LAN access: Best for 4K remux playback
  • NFS alternative: Not recommended over Tailscale (slower than SMB in testing)
