Unable to SSH to nodes, plz help

[Nicholas Chernosky]

Got myself the clusterhat 2.5 with a raspberry pi 4, and 4 rpi zero 2w. I booted it up initially and it worked fine, able to ssh in right out of the box with default 64bit lite images for the zeros and the 64bit CNAT desktop version for the pi4.

The issue came up when I found a larger 128gb SD card in my desk and decided I'd rather have that for a bit more storage, flashed the image on there, and once I boot up I can't SSH in. So I figure there must be some automatic clusterhat setup on first boot or something and reflash all 5 SD cards, still SSH does not work, no route to host. Since then I've tried every guide on setup I can find, reflashed cards and started from scratch a few times, but ever since second boot I haven't been able to SSH into the nodes at all, and I have no clue why, kind of at a loss here.

Hi, 

The issue came up when I found a larger 128gb SD card in my desk and decided I'd rather have that for a bit more storage, flashed the image on there, and once I boot up I can't SSH in.

Are you able to connect locally with a keyboard/monitor to the controller to check it's booting up and on the IP you're trying to connect to (also checking you enabled SSH when writing the images)?

Please also remember it will take a while when using a 128GB SD card to resize the filesystem on the first boot.

Chris.

Which version of pi os are you using?

 

If previous to bookworm, try touching /boot/ssh on each pi zero card image.

If bookworm, then touch /boot/firmware/ssh

 

See if that helps as it would enable the ssh.  If did re-flash each card, then you may also have to create the userconf.txt with username:encrypted password on it on each image also.
