Recent Issues and Solutions

Segmentation Fault Resolution (Aug 14, 2025)

  • Issue: Corrupted log_message function in autonas-manager.sh causing segfaults
  • Cause: During refactoring, sync code from cleanup_and_unmount was embedded into log_message function
  • Solution: Repaired log_message function by removing embedded sync code that executed at global scope
  • Status: ✅ RESOLVED - All nodes functioning correctly

Configuration Loss

  • Issue: /etc/pve/autonas/disks.conf configurations disappeared
  • Possible Cause: Unknown - may be related to system cleanup or restart
  • Recovery: Manual reconstruction using lsblk and blkid to identify disk UUIDs
  • Prevention: Regular backups of configuration file

✅ AutoNAS Script Unification COMPLETE! (August 14, 2025)

Successfully Unified: autonas.sh

Deployed on all nodes: - 192.168.2.91 (baobab) - Unified script active - 192.168.2.92 (ebony) - Unified script active - 192.168.2.93 (tapia) - Unified script active

Unified Command Interface:

autonas attach <uuid>       # Disk operations
autonas detach <uuid>
autonas list               # Configuration management  
autonas add [uuid]
autonas show               # Device discovery
autonas status             # System status

Functions Successfully Integrated:

Disk Operations (from autonas-manager.sh): - handle_attach(), handle_detach(), mount_disk(), unmount_disk() - activate_ip(), deactivate_ip(), add_nfs_export(), remove_nfs_export() - handle_camera_import(), run_background_import()

Configuration Management (from autonas-config.sh): - list_disks(), show_available_disks(), validate_uuid(), check_uuid_exists() - get_device_info(), unified parsing and status display

System Integration: - Unified logging with LOG_TAG="autonas" - Single configuration file parsing - Consistent error handling and status reporting

Deployment Results:

✓ Unified AutoNAS script installed
✓ Created 'autonas' command symlink  
✓ Unified script: /usr/local/bin/autonas.sh

Validated Operations:

  • autonas --help ✅ Complete help system
  • autonas list ✅ Configuration display (3 disks shown perfectly)
  • autonas show ✅ Device discovery (6 devices detected)
  • autonas attach 8765-4321 ✅ Camera import process (working)
  • autonas status ✅ System status (working with minor display issue)

Code Reduction Achievement:

  • Before: 699 + 1720 = 2419 lines (two separate scripts)
  • After: ~2100 lines (single unified script)
  • Reduction: ~13% code reduction + eliminated duplication
  • Maintenance: Single script to maintain vs. two scripts

Legacy Scripts Status:

  • autonas-manager.sh ✅ Still available for compatibility
  • autonas-config.sh ✅ Still available for compatibility
  • autonas.shNEW unified interface (recommended)

🔄 Script Unification Analysis (August 14, 2025)

Identified Function Overlaps:

autonas-manager.sh (699 lines) vs autonas-config.sh (1720 lines)

Duplicate Functions:

  1. Configuration Parsing:

    • get_disk_config() vs get_config() - Same functionality
    • parse_config() vs multiple IFS=':' read -r uuid name... patterns
  2. File System Operations:

    • mount_disk() vs mount_disk_config() - Similar mounting logic
    • unmount_disk() vs umount_disk_config() - Similar unmounting logic
  3. Device Detection:

    • Similar UUID validation and device scanning in both scripts

Unification Proposal: autonas.sh

Created unified script skeleton with: - Combined logging system (LOG_TAG="autonas") - Unified configuration parsing - Single command dispatcher: autonas <command> [options] - Core disk operations (attach, detach, mount, unmount) - Configuration management (add, remove, list, test)

Command Structure:

# Disk Operations (from manager)
autonas attach <uuid>
autonas detach <uuid> 
autonas reload

# Configuration (from config)
autonas add [uuid]
autonas remove [uuid]
autonas list
autonas test [uuid]
autonas show

# Maintenance
autonas mount <uuid>
autonas umount <uuid>
autonas status

Benefits of Unification:

  • Reduced Code Duplication: ~40% code reduction estimated
  • Consistent Interface: Single entry point for all operations
  • Simplified Maintenance: One script to debug and update
  • Better Error Handling: Unified logging and error reporting

Implementation Status:

  • ✅ Core manager functions integrated
  • ⏳ Configuration functions need integration (~1200 lines from config.sh)
  • ⏳ Testing and validation required
  • ⏳ Deployment script updates needed

✅ AutoNAS Media Importer Integration Complete!

Key Simplification: Non-Configurable Media Importer (August 14, 2025)

Media importer script is now built-in and non-configurable: - Script path: /usr/local/bin/autonas-media-importer.sh (hardcoded) - Configuration format simplified: UUID:name:IMPORT:IMPORT:temp_mount_point:destination_path - Removed redundant script_path parameter from camera configurations - Updated display logic to show "(built-in, non-configurable)" status

Rationale:

  • autonas-media-importer.sh is a core component with deep system integration
  • Making it configurable would require extensive testing and validation
  • Single, well-tested importer ensures consistent behavior across all cameras
  • Simplified configuration reduces user error and maintenance complexity

Final Deployment Status (August 14, 2025)

Version Deployed: AutoNAS v2.1 (Optimized & Segfault-Free)

Successfully deployed on all nodes: - 192.168.2.91 (baobab.vad.is.xdev.ro) - NFS Consumer - 192.168.2.92 (ebony.vad.is.xdev.ro) - Storage Provider (ext01) - 192.168.2.93 (tapia.vad.is.xdev.ro) - Storage Provider (ext02)

Key Fixes Deployed:

  1. Segmentation Fault Resolution: Corrupted log_message function repaired
  2. Configuration Recovery: All 3 disk configurations restored with backups
  3. Architecture Optimization: Simplified system with removed orphan components
  4. Logging Standardization: Global LOG_TAG system implemented
  5. Boot Scan Service: Fully functional auto-detection at boot

Current System State:

  • ✅ All core functionality working
  • ✅ Configuration backups created with timestamps
  • ✅ No segmentation faults on any node
  • ✅ udev-based reactive monitoring active
  • ✅ SystemD integration optimized

Validated Operations:

ssh -l root 192.168.2.92 'autonas-manager.sh attach f6ac3d86-5681-4b33-bc64-aa272b333057'  # ✅ Works
ssh -l root 192.168.2.93 'autonas-config.sh list'                                           # ✅ Works  
ssh -l root 192.168.2.91 'autonas-manager.sh reload'                                        # ✅ Works

Critical Reminders

  1. Always use root user for AutoNAS operations
  2. Backup configurations before major changes
  3. Test on single node before mass deployment
  4. Monitor logs during operations for early issue detection
  5. Keep development context updated with any architecture changes
