Hello,
After initializing with region+rack my controller is reported as “Region Controller” only, hence my images status are always "Waiting for rack controller(s) to sync ", I guess as I do not have a rack controller …
“Error:Unable to start the pod discovery process. No rack controllers connected.”
how can I guess this sorted?
Thanks
Hi, could you please provide which version of maas you’re using, exact steps you’ve taken to initialize it, and also if you see errors in /var/snap/maas/common/logs/{regiond,rackd}.log?
Hi ack,
Thanks for the reply, I have installed MAAS 3.0 using snap as described in the installation documentation (https://maas.io/docs/snap/3.0/ui/maas-installation), then used the test db (maas-test-db).
looking at the logs regiond.log doesn’t show any but rackd.log is reporting this:

192.168.122.1 is actually the KVM bridge interface used to created the KVM guest instances “virt-install --name guest1-ubuntu --memory 2048 --vcpus 2 --disk size=8 --network=bridge:virbr0 --pxe --os-variant ubuntu20.10” as I followed the “give me an example of MAAS” guide (https://maas.io/docs/snap/3.0/ui/give-me-an-example-of-maas)
Also this is running on a freshly installed Ubuntu 21.04
Best Regards,
Ok, I’v got it I think 69 is TFTP, I installed a tftp server while following these instructions: http://jefflane.org/v2/technology/setting-up-kvm-to-pxe-boot-virtual-machines-from-a-local-tftp-server/
So I guess MAAS has it’s own built in TFTP server
Thanks for pointing in the right direction
