|
||||
1. **Path Traversal Protection**
|
||||
- Validates all tape paths
|
||||
- Blocks `..` and `/` in patterns
|
||||
- Ensures operations stay within `/opt/mhvtl/`
|
||||
|
||||
2. **Input Validation**
|
||||
- Barcode prefix: max 6 characters
|
||||
- Tape count: 1-100 limit
|
||||
- Media type: whitelist validation
|
||||
- Density: whitelist validation
|
||||
|
||||
3. **Sudo Configuration**
|
||||
- Limited sudo access for www-data
|
||||
- Only specific commands allowed
|
||||
- No password required for allowed operations
|
||||
|
||||
4. **Error Handling**
|
||||
- Graceful error messages
|
||||
- Partial success reporting
|
||||
- Detailed error logs
|
||||
|
||||
### Sudoers Configuration
|
||||
|
||||
File: `/etc/sudoers.d/mhvtl`
|
||||
|
||||
```bash
|
||||
# Allow www-data to manage mhvtl
|
||||
www-data ALL=(ALL) NOPASSWD: /bin/systemctl restart mhvtl
|
||||
www-data ALL=(ALL) NOPASSWD: /bin/systemctl start mhvtl
|
||||
www-data ALL=(ALL) NOPASSWD: /bin/systemctl stop mhvtl
|
||||
www-data ALL=(ALL) NOPASSWD: /bin/systemctl status mhvtl
|
||||
www-data ALL=(ALL) NOPASSWD: /bin/rm -rf /opt/mhvtl/*
|
||||
|
||||
# Same for apache (RPM-based systems)
|
||||
apache ALL=(ALL) NOPASSWD: /bin/systemctl restart mhvtl
|
||||
apache ALL=(ALL) NOPASSWD: /bin/systemctl start mhvtl
|
||||
apache ALL=(ALL) NOPASSWD: /bin/systemctl stop mhvtl
|
||||
apache ALL=(ALL) NOPASSWD: /bin/systemctl status mhvtl
|
||||
apache ALL=(ALL) NOPASSWD: /bin/rm -rf /opt/mhvtl/*
|
||||
```
|
||||
|
||||
### Command Generation
|
||||
|
||||
The `mktape` command is executed as:
|
||||
|
||||
```bash
|
||||
mktape -l <library> -m <barcode> -s <size_MB> -t <type> -d <density>
|
||||
```
|
||||
|
||||
**Example:**
|
||||
```bash
|
||||
mktape -l 10 -m CLN000100 -s 2500000 -t data -d LTO6
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
### CRUD Test Results
|
||||
|
||||
```bash
|
||||
=== CRUD TEST ===
|
||||
1. CREATE: ✅ success:true
|
||||
2. READ: ✅ "name":"CRUD000001", "name":"CRUD000002"
|
||||
3. DELETE: ✅ success:true
|
||||
4. VERIFY: ✅ Only CRUD000002 remains
|
||||
```
|
||||
|
||||
### Performance
|
||||
|
||||
- **Create 1 tape**: ~1 second
|
||||
- **Create 10 tapes**: ~3 seconds
|
||||
- **List 100 tapes**: <1 second
|
||||
- **Delete 1 tape**: ~1 second
|
||||
- **Bulk delete 50 tapes**: ~3 seconds
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Issue: "Permission denied" when creating tapes
|
||||
|
||||
**Solution:**
|
||||
1. Check www-data is in vtl group: `groups www-data`
|
||||
2. Check /opt/mhvtl permissions: `ls -ld /opt/mhvtl`
|
||||
3. Restart Apache: `systemctl restart apache2`
|
||||
|
||||
### Issue: "Failed to delete tape"
|
||||
|
||||
**Solution:**
|
||||
1. Check sudoers file: `cat /etc/sudoers.d/mhvtl`
|
||||
2. Test sudo access: `sudo -u www-data sudo rm -rf /opt/mhvtl/TEST`
|
||||
3. Check tape exists: `ls /opt/mhvtl/`
|
||||
|
||||
### Issue: Tapes not showing in list
|
||||
|
||||
**Solution:**
|
||||
1. Click "🔄 Refresh List" button
|
||||
2. Check browser console for errors (F12)
|
||||
3. Verify API is accessible: `curl http://localhost/mhvtl-config/api.php`
|
||||
|
||||
### Issue: "Invalid density" error
|
||||
|
||||
**Solution:**
|
||||
Use one of the supported densities:
|
||||
- LTO5, LTO6, LTO7, LTO8, LTO9
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Naming Convention**
|
||||
- Use meaningful prefixes (BACKUP, ARCHIVE, TEST, etc.)
|
||||
- Keep prefixes short (3-6 chars)
|
||||
- Use consistent numbering scheme
|
||||
|
||||
2. **Tape Organization**
|
||||
- Group tapes by purpose (prefix)
|
||||
- Use sequential numbering
|
||||
- Document tape usage in external system
|
||||
|
||||
3. **Deletion Safety**
|
||||
- Always confirm before bulk delete
|
||||
- Test patterns with small sets first
|
||||
- Keep backups of important data
|
||||
|
||||
4. **Performance**
|
||||
- Create tapes in batches (10-50 at a time)
|
||||
- Use bulk delete for cleanup
|
||||
- Regular cleanup of unused tapes
|
||||
|
||||
## Future Enhancements

||||
|
||||
- [ ] Edit tape properties (size, type)
|
||||
- [ ] Tape usage statistics
|
||||
- [ ] Export tape list to CSV
