12/28/2023, 7:07 PMHi @salmon-city-57654, thanks for getting back on this. role of the Harvester Node. As we added more nodes, Management nodes are now compute nodes and some compute nodes are management nodes. We want to control which nodes can be Management Nodes for Harvester Cluster.

Bumping this up in case anyone else has any idea to promote the node to Management manually.

01/04/2024, 2:02 AMIf you use kubectl to get nodes, then edit one, you cna change these roles. I am not sure if it is the right place or not, but would be a good start.

01/04/2024, 2:05 AMYeah, i found this code and controller. It doesn’t get rid of etcd even you remove the label from rest of the nodes

01/04/2024, 2:15 AMHi @rapid-iron-53423, did you mean you would like to promote the specific node to master?

01/04/2024, 2:29 AMNow, we only promote the worker node to the master node at the first three nodes. Could you help to create a GH issue for this?
salmon-city-57654
01/04/2024, 2:30 AMI thought you could manually modify the node label as @brainy-whale-97450’s suggestions. That should be worked.

rapid-iron-53423
01/04/2024, 2:31 AMYeah, that worked partially, as i shared in the screenshot etcd still stays on all the nodes

salmon-city-57654
01/04/2024, 2:31 AMI thought that’s a good point. We need to provide a way to let users change the node roles.
r
rapid-iron-53423
01/04/2024, 2:32 AMI will open GH issue with more details to troubleshoot or a possible documentation as there is already controller which is responsible for upgrading the node roles.

01/04/2024, 2:33 AMActually, we are working on a similar concept. hope we can give enough mechanisms for the DR design.

That would be great, thanks!

01/04/2024, 2:34 AMBTW, if you move a node to etcd. You might need to care about the taint. Or some workload would be deployed on it.

01/04/2024, 2:37 AMWe have a feature that will let the user set up the etcd (only) node when installation. This might introduce some mechanism to allow users to control the node role changing.
