[ClusterHAT]

Hi,

does anyone know what are all of the commands within clusterctrl and formats

clusterctrl help # Or -h ,--help, /? should show the commands

There's also a bit of information at the top of the file itself which you can see on https://github.com/burtyb/clusterhat-image/blob/master/files/usr/sbin/clusterctrl

 

im wondering do to this,

root@Host:/home/pi# clusterctrl savepos 1234
Invalid order
Error: Unable to find Cluster CTRL device with that order

 

clusterhat:1
clusterctrl:False

Looking at the output of status you have a clusterhat rather than a clusterctrl device (Triple/Single/Stack) so you wouldn't be able to use savepos.

If you want to power the Pi Zeros on after the controller Pi has started up you can do this using crontab, sadly I can't find the official RPi docs on using cron but you should be able to add it by doing this.

sudo crontab -e

When it asks which editor you want to use you'll probably want to select nano, then go to the end of the file and add this line.

@reboot sleep 30 && /usr/sbin/clusterctrl on

To exit nano and save the file press Ctrl-X, Y and then press Enter.

When you next restart the controller Pi it should then start up the Pi Zeros ~30 seconds after it has started up.

Chris.
