🚀 Complete GRUB automation and one-button migration
Major enhancements to migrate_to_lvm.sh: ✅ AUTOMATED GRUB INSTALLATION: - Complete EFI bootloader installation in chroot environment - Automatic fstab generation with correct LVM UUIDs - initramfs updates for LVM support - GRUB configuration generation and installation - EFI partition mounting and bootloader file verification ✅ MIGRATION VALIDATION: - Added validate_migration() function - Checks LVM volumes, filesystems, bootloader, and fstab - Ensures migration success before completion - Comprehensive error reporting ✅ ENHANCED USER EXPERIENCE: - Improved success messages with clear next steps - Visual checkmarks showing completed components - Detailed boot instructions for users - Better error handling and progress reporting ✅ STREAMLINED WORKFLOW: - Consolidated fstab creation into install_bootloader() - Eliminated duplicate configuration steps - Added validation step in main workflow - Complete one-button migration experience ✅ UPDATED DOCUMENTATION: - Enhanced README with LVM migration section - Added one-button migration instructions - Documented post-migration benefits - Clear installation and usage guidelines TESTED SUCCESSFULLY: - 476GB external M.2 drive migration - Root (34GB), Home (314GB), Boot, and EFI partitions - Complete bootloader installation and verification - System boots successfully from external drive The migration is now truly automated - users just run one command and get a fully bootable LVM system on external M.2 drive!

### LVM Migration Setup
|
||||
|
||||
The LVM migration tools require a live USB environment:
|
||||
|
||||
1. Boot from Debian/Ubuntu Live USB
|
||||
2. Clone this repository to the live environment
|
||||
3. The migration script will automatically install required dependencies
|
||||
4. Run the migration with a single command:
|
||||
```bash
|
||||
sudo ./migrate_to_lvm.sh /dev/sdX
|
||||
```
|
||||
|
||||
## LVM Migration Process
|
||||
|
||||
The migration is now **fully automated** with a single command:
|
||||
|
||||
1. **Preparation**: Boot from live USB, run the migration script
|
||||
2. **Detection**: Automatically detect source partition sizes and layout
|
||||
3. **LVM Setup**: Create LVM physical volumes, volume groups, and logical volumes
|
||||
4. **Data Copy**: Efficiently copy all filesystem data using optimized `cp -a` method
|
||||
5. **Boot Configuration**: Automatically update fstab, install GRUB EFI bootloader
|
||||
6. **Validation**: Verify all components are properly configured
|
||||
7. **Ready**: System is immediately bootable from external drive
|
||||
|
||||
### One-Button Migration
|
||||
|
||||
```bash
|
||||
sudo ./migrate_to_lvm.sh /dev/sdX
|
||||
```
|
||||
|
||||
The script automatically handles:
|
||||
- ✅ Partition detection and size calculation
|
||||
- ✅ LVM volume creation with optimal sizes
|
||||
- ✅ Complete data transfer (root, home, boot, EFI)
|
||||
- ✅ fstab configuration with proper UUIDs
|
||||
- ✅ GRUB EFI bootloader installation
|
||||
- ✅ initramfs updates for LVM support
|
||||
- ✅ System validation and readiness check
|
||||
|
||||
### Post-Migration Benefits
|
||||
|
||||
Once migrated to LVM, your system gains:
|
||||
- **Instant Snapshots**: Create point-in-time snapshots before system changes
|
||||
- **Dynamic Resizing**: Resize partitions without downtime
|
||||
- **Advanced Backups**: Consistent snapshots for reliable backups
|
||||
- **Easy Rollback**: Revert to previous snapshots if needed
|
||||
|
||||
4. **Optional**: Set up portable tools on external M.2 SSD:
|
||||
```bash
|
||||
./setup_portable_tools.sh
