LVM Migration Setup Instructions
|
||||
===============================
|
||||
|
||||
1. Boot from this USB stick into live system
|
||||
2. Open terminal and run: sudo -i
|
||||
3. Run: /media/*/migration_tools/bootstrap.sh
|
||||
OR manually follow these steps:
|
||||
|
||||
Manual Setup:
|
||||
1. Update packages: apt update
|
||||
2. Install tools: apt install -y lvm2 cryptsetup rsync parted pv grub-efi-amd64
|
||||
3. Load modules: modprobe dm_mod dm_crypt dm_snapshot
|
||||
4. Create workspace: mkdir -p /tmp/lvm-migration && cd /tmp/lvm-migration
|
||||
5. Copy migration scripts from external drive or USB
|
||||
6. Run: ./migrate_to_lvm.sh
|
||||
|
||||
Drive Configuration (adjust as needed):
|
||||
- Internal drive: /dev/nvme0n1 (source)
|
||||
- External M.2: /dev/sdc (target)
|
||||
- USB stick: /dev/sdb (tools)
|
||||
|
||||
Important Notes:
|
||||
- This will DESTROY all data on the external M.2 drive
|
||||
- Internal drive remains unchanged as backup
|
||||
- External M.2 will become bootable LVM system
|
||||
- Update BIOS boot order after migration
