Teaching and learning resources • Re: Gap in "How to build a Raspberry Pi Cluster"

There is a Gap in the Guide on "How to build a Raspberry Cluster" https://www.raspberrypi.com/tutorials/c ... -tutorial/

When setting up the first compute node there is a missing command. Right after creating the boot image there should be this command:

Code:

echo "/mnt/usb/rpi1/boot/firmware /mnt/usb/tftpboot/6a5ef8b0 none defaults,bind 0 0" >> /etc/fstab

I went through the Guide and was stuck here a bit until I had a look further on how to add all the next compute nodes and found the command that was missing in the Guide section for rpi1

Code:

echo "/mnt/usb/rpi2/boot/firmware /mnt/usb/tftpboot/54e91338 none defaults,bind 0 0" >> /etc/fstab

I changed that to the command like above and then the rpi1 was able to boot. Before it was requesting the boot files over TFTP but was not getting an answer because /mnt/usb/tftpboot/6a5ef8b0 was empty.
