# NAS Mount Setup Guide for Fedora 42

## Quick Setup Instructions

Your NAS IP: `192.168.68.51`
Mount Point: `/mnt/share/media`

### Prerequisites (Already Installed)
- `cifs-utils` - for SMB/CIFS mounting
- `nfs-utils` - for NFS mounting

### Option 1: Automated Setup (Recommended)

Run the interactive setup script:
```bash
./setup-nas-mount.sh
```

This script will:
- Test both SMB and NFS connectivity
- Guide you through the setup process
- Create persistent mount configuration
- Set up systemd mount units for reliable boot mounting

### Option 2: Manual SMB/CIFS Setup

1. **Test SMB shares first:**
   ```bash
   # List available shares (you'll need NAS credentials)
   smbclient -L 192.168.68.51 -U your_username
   ```

2. **Create credentials file (if using authentication):**
   ```bash
   sudo tee /etc/nas-credentials << EOF
   username=your_nas_username
   password=your_nas_password
   domain=WORKGROUP
   EOF
   sudo chmod 600 /etc/nas-credentials
   ```

3. **Test mount:**
   ```bash
   # With credentials
   sudo mount -t cifs //192.168.68.51/share_name /mnt/share/media -o credentials=/etc/nas-credentials,uid=$(id -u),gid=$(id -g),iocharset=utf8

   # Or for guest access
   sudo mount -t cifs //192.168.68.51/share_name /mnt/share/media -o guest,uid=$(id -u),gid=$(id -g),iocharset=utf8
   ```

4. **Add to /etc/fstab for persistence:**
   ```bash
   # Backup fstab first
   sudo cp /etc/fstab /etc/fstab.backup

   # Add entry (with credentials)
   echo "//192.168.68.51/share_name /mnt/share/media cifs credentials=/etc/nas-credentials,uid=$(id -u),gid=$(id -g),iocharset=utf8,noauto,user 0 0" | sudo tee -a /etc/fstab

   # Or for guest access
   echo "//192.168.68.51/share_name /mnt/share/media cifs guest,uid=$(id -u),gid=$(id -g),iocharset=utf8,noauto,user 0 0" | sudo tee -a /etc/fstab
   ```

### Option 3: Manual NFS Setup

1. **Check available NFS exports:**
   ```bash
   showmount -e 192.168.68.51
   ```

2. **Test mount:**
   ```bash
   sudo mount -t nfs 192.168.68.51:/path/to/export /mnt/share/media -o rw,hard,intr
   ```

3. **Add to /etc/fstab:**
   ```bash
   echo "192.168.68.51:/path/to/export /mnt/share/media nfs rw,hard,intr,rsize=8192,wsize=8192,timeo=14,noauto,user 0 0" | sudo tee -a /etc/fstab
   ```

### Systemd Mount Unit (For Reliable Boot Mounting)

Create `/etc/systemd/system/mnt-share-media.mount`:

```ini
[Unit]
Description=Mount NAS Media Share
After=network-online.target
Wants=network-online.target

[Mount]
What=//192.168.68.51/share_name
Where=/mnt/share/media
Type=cifs
Options=credentials=/etc/nas-credentials,uid=1000,gid=1000,iocharset=utf8

[Install]
WantedBy=multi-user.target
```

Enable it:
```bash
sudo systemctl daemon-reload
sudo systemctl enable mnt-share-media.mount
sudo systemctl start mnt-share-media.mount
```

### Common Commands

- **Mount manually:** `sudo mount /mnt/share/media`
- **Unmount:** `sudo umount /mnt/share/media`
- **Check mount status:** `df -h /mnt/share/media`
- **Test systemd mount:** `sudo systemctl start mnt-share-media.mount`

### Troubleshooting

1. **Check connectivity:**
   ```bash
   ping 192.168.68.51
   ```

2. **Test SMB connection:**
   ```bash
   nc -zv 192.168.68.51 445
   ```

3. **Test NFS connection:**
   ```bash
   nc -zv 192.168.68.51 2049
   ```

4. **Check mount logs:**
   ```bash
   journalctl -u mnt-share-media.mount
   ```

5. **Verify fstab syntax:**
   ```bash
   sudo mount -a
   ```

### Security Notes

- Credentials file should have 600 permissions (readable only by root)
- Consider using NFS over SMB for better performance on Linux
- Use `noauto` in fstab to prevent boot delays if NAS is unavailable
- The `user` option allows regular users to mount/unmount

### Integration with Your Backup Scripts

Your `backup-media.sh` script already references `/mnt/share/media/backups`, so once the NAS is mounted, your backups will automatically work with the NAS storage.

Make sure your backup script has proper error handling for when the NAS is not mounted:

```bash
# Add this check to your backup scripts
if ! mountpoint -q /mnt/share/media; then
    log_error "NAS not mounted at /mnt/share/media"
    exit 1
fi
```
