- Fixed integer expression errors in size calculations - Improved partition detection to avoid 'not a block device' errors - Added proper device cleanup before wiping to fix 'device busy' issues - Implemented smart space allocation for same-size drives - Added robust partition table handling with retry logic - Changed VG name to 'migration-vg' to avoid conflicts - Script now properly calculates sizes: 56GB root + 404GB home + 8GB swap + 2GB boot = 470GB total - Tested with 476GB drives - fits perfectly with optimal space utilization

=== LVM MIGRATION OPTIONS ===
|
|
|
|
You now have TWO migration options on this USB stick:
|
|
|
|
OPTION 1: IMPROVED LVM MIGRATION (Recommended)
|
|
File: improved_lvm_migration.sh
|
|
- Fixes the boot issues from the previous failed attempt
|
|
- Properly configures initramfs with LVM modules
|
|
- Better GRUB configuration for LVM
|
|
- Handles LUKS + LVM combination correctly
|
|
- More robust error handling
|
|
|
|
OPTION 2: SIMPLE 1-TO-1 CLONE (Fallback)
|
|
File: direct_clone_backup.sh
|
|
- Creates exact copy without LVM conversion
|
|
- Use if LVM migration still has issues
|
|
|
|
=== WHAT WAS WRONG WITH PREVIOUS LVM MIGRATION ===
|
|
|
|
The original migrate_to_lvm.sh failed because:
|
|
❌ Initramfs missing LVM modules
|
|
❌ Poor GRUB LVM configuration
|
|
❌ LUKS + LVM combination issues
|
|
❌ Insufficient boot verification
|
|
|
|
=== IMPROVEMENTS IN NEW LVM SCRIPT ===
|
|
|
|
✅ Proper initramfs LVM module inclusion
|
|
✅ Correct GRUB configuration for LVM
|
|
✅ Better LUKS + LVM handling
|
|
✅ Boot configuration verification
|
|
✅ More robust error recovery
|
|
|
|
=== USAGE INSTRUCTIONS ===
|
|
|
|
1. Boot from this USB stick (Debian Live)
|
|
|
|
2. For LVM migration (recommended):
|
|
sudo ./improved_lvm_migration.sh
|
|
|
|
3. For simple clone (if LVM fails):
|
|
sudo ./direct_clone_backup.sh
|
|
|
|
4. Verify boot readiness:
|
|
sudo ./verify_boot_readiness.sh
|
|
|
|
5. If needed, repair issues:
|
|
sudo ./boot_repair_tools.sh
|
|
|
|
=== EXPECTED RESULTS WITH IMPROVED LVM ===
|
|
|
|
✅ Boots properly asking for LUKS password
|
|
✅ No reset loops or boot failures
|
|
✅ Full LVM functionality (snapshots, resizing)
|
|
✅ Proper initramfs with LVM support
|
|
✅ Working GRUB configuration
|
|
|
|
The improved script addresses all the issues that caused

the boot failure shown in your screenshot.
