Error adding new master node to K8S cluster

I’m looking to add a new master node to a K8S cluster. I am getting an error

Error: error attaching node. Error: waiting for etcd members to start

I tried to deauthorize and then re-authorize the node but that didn’t work.

The issue may be that the master node attach operation was initiated before the detach could complete, which can result in having an unstarted member in the etcd when attachMaster is called.
If you remove the unhealthy master’s entry from the etcd, and then try to add the new master to the cluster again, that may resolve the issue.

Thanks for the fix, that worked!

Sure! If it’s of interest, if you’re on our growth or enterprise plans we can handle etcd management for you. We can do the necessary checks and backups, if required, before making any change.
