Enhanced World Deletion

Comprehensive world deletion with configuration purging

Overview

LilWorlds v1.2+ features enhanced world deletion that goes beyond simply removing world files. The deletion process includes comprehensive configuration purging to ensure no orphaned entries remain in your server configuration.

Important: World deletion is permanent and cannot be undone. Always create backups before deleting important worlds.

Configuration Purging Details

Main Configuration (config.yml)

The deletion process removes world references from:

# Before deletion
inventory-groups:
  survival:
    - world
    - myworld        # ← This will be removed
    - world_nether
  creative:
    - creative_world
    - myworld        # ← This will also be removed

world-groups:
  main:
    - world
    - myworld        # ← Removed from here too

# After deletion - myworld completely removed
inventory-groups:
  survival:
    - world
    - world_nether
  creative:
    - creative_world

world-groups:
  main:
    - world

World Configuration (worlds.yml)

Complete world entry removal:

# Before deletion

Best Practices

Before Deletion

Pre-Deletion Checklist:

• ✅ Verify you have the correct world name
• ✅ Check if anyone is currently using the world
• ✅ Create a backup if the world might be needed later
• ✅ Inform other admins/players about the deletion
• ✅ Document the reason for deletion

Deletion Strategy

# Recommended deletion workflow
deletion-workflow:
  1. Announce planned deletion to players
  2. Create backup if world has value
  3. Move players out of world
  4. Unload world temporarily to test
  5. Verify no issues with world offline
  6. Proceed with deletion
  7. Monitor for any issues post-deletion

Regular Maintenance

Schedule regular cleanup:

# Weekly cleanup script
#!/bin/bash
echo "Starting weekly world cleanup..."

# Remove temporary worlds older than 7 days
/world remove --pattern "temp_*" --older-than 7d

# Clean up orphaned configurations
/worlds cleanup --config

# Remove unused backup worlds
/worlds cleanup --backups --keep 10

echo "Cleanup completed!"

Troubleshooting

Common Issues

Deletion Fails

Symptoms: World deletion command fails or hangs

Solutions:

• Check if players are still in the world
• Verify sufficient disk space for operations
• Check file permissions on world folder
• Try unloading world first: /world unload myworld
• Check console for specific error messages

Configuration Not Purged

Symptoms: World still appears in config files after deletion

Solutions:

• Manually edit configuration files
• Use /worlds reload to refresh configs
• Check for syntax errors in config files
• Verify purge-config: true in settings

Players Not Evacuated

Symptoms: Players remain in world during deletion

Solutions:

• Manually teleport players: /tp @a spawn
• Check spawn world is loaded and accessible
• Verify teleportation permissions
• Use /world unload myworld --force if needed

Recovery Procedures

If deletion goes wrong:

1. Stop Server Immediately

   Prevent further damage by stopping the server

2. Assess Damage

   Check what was actually deleted vs. what should have been

3. Restore from Backup

   Use file system backups to restore deleted content

4. Fix Configuration

   Manually restore configuration entries if needed

5. Test Thoroughly

   Verify everything works before allowing players back
