AutoNAS - Unified AutoNAS Management Tool

Usage: $0 <command> [options]

DISK OPERATIONS:
  attach <uuid|name|mount>   - Attach configured disk
  detach <uuid|name|mount>   - Detach configured disk
  import <uuid> <source> <dest> [script] - Run background import (internal use)
  reload                     - Reload AutoNAS configuration

CONFIGURATION MANAGEMENT:
  add [uuid]                 - Add new disk configuration
  remove [uuid|name|mount]   - Remove disk configuration
  list                       - List all configured disks
  test [uuid|name|mount]     - Test disk configuration
  show                       - Show available disks

MAINTENANCE:
  status                     - Show system status
  debug enable               - Enable debug mode (verbose logging)
  debug disable              - Disable debug mode
  debug status               - Show current debug status
  
Examples:
  $0 attach f6ac3d86-5681-4b33-bc64-aa272b333057
  $0 add 8765-4321
  $0 list
  $0 show
