📘 NFS Permissions Fix -Boot Script

Purpose

Ensure that a mounted NFS share has correct ownership and permissions for Docker containers every time the server boots.

1. Create a Permission Fix Script

Create a simple script that will reset ownership and permissions on the NFS mount point after boot.

bash
sudo nano /usr/local/bin/fix-nfs-permissions.sh

Paste inside the script:

#!/bin/bash
# Fix NFS ownership
chown -R youruser:yourgroup /srv/nfs-mount
chmod -R 775 /srv/nfs-mount

(Replace youruser and yourgroup with your actual username and group.)

2. Make the Script Executable

sudo chmod +x /usr/local/bin/fix-nfs-permissions.sh

3. Create a systemd Service

Create a small service that runs the script automatically at boot:

sudo nano /etc/systemd/system/fix-nfs-permissions.service

Add this content:

[Unit]
Description=Fix NFS Permissions at Boot
After=network.target nfs-client.target remote-fs.target

[Service]
Type=oneshot
ExecStart=/usr/local/bin/fix-nfs-permissions.sh

[Install]
WantedBy=multi-user.target

4. Enable and Start the Service

# Reload systemd to recognize the new service
sudo systemctl daemon-reload

# Enable it to start at every boot
sudo systemctl enable fix-nfs-permissions.service

# Run it now without rebooting (optional)
sudo systemctl start fix-nfs-permissions.service

🚀 Summary

  • Creates a simple fix script for NFS permissions
  • Automates it via systemd on every reboot
  • Useful for Docker setups that rely on consistent NFS access

🛠️ Useful Commands

# Check service status
sudo systemctl status fix-nfs-permissions.service

# Manually trigger the script
sudo /usr/local/bin/fix-nfs-permissions.sh

Tip: You can combine this technique with your Docker container volumes to ensure permissions stay stable even after a server or NFS reboot! 🎯
