Compute Node not in database
While working on Lab 3.4 I tried to remove the "compute-node" from the Compute Hosts, but I couldn't find it in the database. The SQL select shows only one host "devstack-cc", but the other compute host "compute-node" is still listed in the BUI. What am I doing wrong?
mysql> select * from compute_nodes;

Another question on the preconfigured lab links: When I click on them I am supposed to get a preconfigured environment, right? Just to rule out I made a mistake while working up to that point ...

P.S. I tried to upload a screenshot of the BUI to this post. This seems to have failed with an error "Warning! - Failed to move file."0

Thank you for the feedback. I was able to reproduce the issue you are seeing, the compute node has not been added to the cluster as it should have been. I am contacting the infrastructure team to fix it.0
