4.5 SSD Mount

An NVMe SSD is pre-installed in the onboard computer. To use the SSD, you need to initialize the partition, mount it, and register it in /etc/fstab so it mounts automatically after reboot.

Partition Initialization

1. SSD Partition Initialization

   sudo /sbin/parted /dev/nvme0n1 mklabel gpt --script
   sudo /sbin/parted /dev/nvme0n1 mkpart primary ext4 0% 100% --script
   sudo mkfs.ext4 /dev/nvme0n1p1

2. Create Mount Directory and Temporary Mount

   sudo mkdir -p {mount path}
   sudo mount /dev/nvme0n1p1 {mount path}
   sudo chmod 777 {mount path}

Permanent Mount

1. Check UUID

   sudo blkid /dev/nvme0n1p1

   Example output:

   /dev/nvme0n1p1: UUID="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" BLOCK_SIZE="4096" TYPE="ext4"

2. Register Permanent Mount in /etc/fstab

   # Backup existing fstab
   sudo cp /etc/fstab /etc/fstab.bak
   
   # Add entry to fstab (replace {UUID} with the value from above)
   echo 'UUID={UUID}  {mount path}  ext4  defaults,nofail  0  2' | sudo tee -a /etc/fstab

3. Apply and Verify Mount

   # Unmount temporary mount and remount via fstab
   sudo umount {mount path}
   sudo mount -a
   
   # Verify mount
   df -h | grep {mount path}

   If mounted successfully, the {mount path} path and its capacity will be displayed. The SSD will be automatically mounted after reboot.
