Compute nodes don't show when verifying operation

Hello, I've been trying to setup a multi-node OpenStack cloud by following https://docs.openstack.org/devstack/latest/guides/multinode-lab.html (https://docs.openstack.org/devstack/l...). The installation works fine but when I try to verify the operation afterwards with openstack compute service list on my control node, my compute nodes don't show up. Any ideas what my mistake could be?

Thanks, Lauritz

The controller only knows those compute nodes where nova-compute was able to register. Check the nova-compute logs on the compute nodes for registration failures:

journalctl -u devstack@n-cpu

Thank you for the help. Apparently my error was not waiting until the controller was stacked before stacking the compute nodes. I had some additional trouble because the FLOATING_RANGE in my local.conf files was overlapping with the addresses of the actual machines.

Thanks again!

What below command returns when running on a compute node? su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
