Successfully Migrated: Raspiblitz from 1TB to 2TB Drive ✅
To fully clone a Raspiblitz drive – including applications, data, and Lightning channels – 1:1
🕒 Duration: approx. 2 hours
🖥️ System: Linux PC / Ubuntu Desktop
🔌 Equipment: Active USB hub, e.g. this one
Step-by-Step Guide 🔧
1. Preparation
- Properly shut down the Raspiblitz.
- Disconnect the external 1TB drive.
2. Cabling
- Connect the USB hub to the power supply and to the Linux PC.
- Enable two ports, first plug in the old 1TB drive, then the new 2TB drive.
3. Check Devices
lsblk
Example output:
sda 931.5G # Source: old drive sdb 1.8T # Target: new drive
4. Clone the Drive (1:1)
sudo dd if=/dev/sda of=/dev/sdb bs=4M status=progress
➡️ Fully clones the old drive to the new one, bit by bit.
5. Flush Write Cache
sudo sync
➡️ Ensures that all data is actually written to the drive.
6. Disconnect & Reconnect Drives
- Unmount both drives (e.g. via file manager or
umount
). - Reconnect only the newly cloned drive.
7. Check Size
lsblk
➡️ The new 2TB drive will initially show only the old (1TB) size.
8. Expand Partition with GParted
sudo apt install gparted gparted
- Select the new drive.
- Extend the partition to full size using the slider.
- Apply the changes and wait for the process to finish.
9. Reconnect & Reboot
- Connect the new drive to the Raspiblitz.
- Start the Raspiblitz – everything should work as before, just with more space.
- It’s best to securely wipe the old drive now.
🏁 Conclusion
The migration went smoothly. dd
creates an exact 1:1 copy, and gparted
makes full use of the new drive’s storage.
