Step 1: Mount the 1TB SSD

• Prepare the 1TB SSD: You’ll need to format it with a filesystem like BTRFS.

sudo mkfs.btrfs -f /dev/sdX

• Mount the 1TB SSD:

sudo mkdir /mnt/home
sudo mount /dev/sdX /mnt/home

Step 2: Move Data from /home (512GB SSD) to /mnt/home (1TB SSD)

• Move the data: You can use rsync to move the data from the old /home to the new SSD. This ensures permissions and data are properly copied.

sudo rsync -avh --progress /home/ /mnt/home/

This command will recursively copy everything from /home on the 512GB SSD to /mnt/home.

• Check that the data has been copied:

ls /mnt/home

Step 3: Update the Mount Point for /home

sudo vim /etc/fstab

Add or modify the line for /home to:

UUID=<UUID of 1TB SSD>  /home  btrfs  defaults  0  0
