Summary

dqlite is crashing when add master node to a cluster

What Should Happen Instead?

joined successful

Reproduction Steps

I’m trying to create a high availability (HA) cluster with 6 servers—3 master nodes and 3 worker nodes. I was able to successfully join the worker nodes, but when I tried to join a master node, I received the message ‘Successfully joined the cluster.’ However, the node isn’t actually joining, and I can see that the dqlite service is restarting continuously.
I’m using Ubuntu 22.04, and I’ve also tried with Ubuntu 20.04. reinstall a few times with different versions, nothing helps

Hi @sharonrosha, could you please share the inspection report tarballs of the two nodes that are involved? Is there anything else on the logs? Are all nodes on the same subnet? Is this issue reproducible? If so, what is the microk8s version?
