Accessing nodes' filesystems

With tpi it's possible to access filesystems of nodes by booting them as a Mass Storage Device (MSD).

  1. Execute a command with a desired node number:
    tpi advanced msd --node 1
  2. Wait for the device to reboot, which should take around 10 seconds.
  3. Create a directory for mounting, if needed:
    mkdir /mnt/raspios
  4. Mount one or more desired partitions:
    mount /dev/sda1 /mnt/raspios
  5. Perform any applicable read or write operations:
    vi /mnt/raspios/config.txt
  6. Unmount the device and reboot:
    umount /dev/sda1
    tpi power off -n 1
    tpi power on -n 1
