Disk Configuration for Jetson Orin (JetPack 6.2)

Portable SSD (exFAT)

On JetPack 6.2, the exFAT file system is not recognized by default. Therefore, you need to perform the following steps to enable exFAT support, ensuring that your portable SSD formatted with exFAT can be properly read and written.

To enable exFAT support on your system, follow these steps:

1. Install the required packages:

   sudo apt install exfatprogs exfat-fuse
   

2. Create a mount point for the SSD:

   sudo mkdir -p /media/T7
   

3. Mount the SSD:

   sudo mount -t exfat-fuse /dev/sda1 /media/T7
   

4. Create a symbolic link to make exFAT mounting more accessible:

   sudo ln -s /usr/sbin/mount.exfat-fuse /sbin/mount.exfat
   

NVME M.2 SSD

1. Identify the device

   # identify the device
   lsblk
   

   Assuming you identify the disk /dev/nvme0n1, this is the device we will mount.

2. Create the partition

   Create a new partition using parted:

   sudo parted /dev/nvme0n1 --script \
     mklabel gpt \
     mkpart primary ext4 0% 100%
   

   Replace /dev/nvme0n1 with the device name identified in step 1.

3. Format the partition

   sudo mkfs.ext4 /dev/nvme0n1p1
   

   Again, replace /dev/nvme0n1 with your actual device name from step 1.

4. Get the partition UUID

   sudo blkid /dev/nvme0n1p1
   

   Replace /dev/nvme0n1p1 with the correct partition name identified in the previous steps. The output will look like this:

   /dev/nvme0n1p1: UUID="4849c3c4-3362-4e89-8457-b4b7d1804602" BLOCK_SIZE="4096" TYPE="ext4" PARTLABEL="primary" PARTUUID="b72a3784-c4ba-454c-98f1-01822c4a695f"
   

5. Create mount point

   Create the directory where the drive will be mounted:

   sudo mkdir -p /media/Data
   

6. Modify /etc/fstab

   sudo gedit /etc/fstab # nano is not available on JetPack 6.2
   

   Add the following line to the end of the file:

   UUID={the UUID you get from the previous command}  /media/Data  ext4  defaults,nofail,x-systemd.device-timeout=10  0  2
   

   Replace {the UUID you got from the previous command} with the actual UUID from step 4.

7. Mount and validate

   Mount all filesystems and check if the new drive is mounted correctly:

   sudo mount -a
   df -h | grep /media/Data
   

   Ensure that /media/Data shows up as the mount point.

8. (optional) Adjust user access

   # Adjust ownership and group
   sudo chown -R cairlab:cairlab /media/Data
      
   # Create a group for data users
   sudo groupadd datausers
   sudo usermod -aG datausers cairlab
      
   # (Optional) Add other users to the group if needed
   # sudo usermod -aG datausers {user_name}
      
   # Change ownership of the mounted directory to root and datausers group
   sudo chown root:datausers /media/Data
      
   # Set read/write permissions for all users
   sudo chmod 777 /media/Data
      
   

This ensures proper access control and permissions for the directory and mounted device.
